what is the partial pressure of carbon dioxide in a container that holds 5.0 moles of co2, 3.0 moles of nitrogen and 1.0 moles of hydrogen and has a total pressure of 1.05 atm
Answers
The partial pressure of carbon dioxide in the container is 0.525 atm.
The partial pressure of a gas is the pressure that it would exert if it occupied the entire volume of the container by itself at the same temperature.
To calculate the partial pressure of carbon dioxide (CO2) in this mixture, we need to first calculate the mole fraction of CO2, which is the ratio of the number of moles of CO2 to the total number of moles in the mixture:
X_CO2 = n_CO2 / (n_CO2 + n_N2 + n_H2)
X_CO2 = 5.0 mol / (5.0 mol + 3.0 mol + 1.0 mol)
X_CO2 = 0.5
Next, we can use the mole fraction to calculate the partial pressure of CO2 using Dalton's law of partial pressures:
P_CO2 = X_CO2 * P_total
P_CO2 = 0.5 * 1.05 atm
P_CO2 = 0.525 atm

The Kelvin temperature of sample of 650 cm sample of ammonia gas is doubled what is the new volume of the gas
Answers
Answer:
1300cm3.
Explanation:
Step 1:
Data obtained from the question.
Initial temperature (T1) = K
Initial volume (V1) = 650 cm3
Final temperature (T2) = double the original = 2K
Final volume (V2) =..?
Step 2:
Determination of the new volume of the gas.
The new volume of the gas can be obtained by using Charles' law as follow:
V1/T1 = V2/T2
650/K = V2/2K
Cross multiply
K x V2 = 650 x 2K
Divide both side by K
V2 = 650 x 2K /K
V2 = 650 x 2
V2 = 1300cm3.
Therefore, the new volume of the gas is 1300cm3
The new volume of the gas is 1300cm³.
Calculation for volume:Given:
Initial temperature (T₁) = K
Initial volume (V₁) = 650 cm3
Final temperature (T₂) = double the original = 2K
To find:
Final volume (V₂) =?
Determination of new volume:
V₁/T₁ = V₂/T₂
650/K = V₂/2K
K x V₂ = 650 x 2K
V₂ = 650 x 2K /K
V₂ = 650 x 2
V₂ = 1300cm³
Therefore, the new volume of the gas is 1300cm³.

Emissions of sulfur dioxide by industry set off chemical changes in the atmosphere that result in acid rain. The acidity of liquids is measured by pH on a scale from 0 to 14. Distilled water has a pH of 7.0 and lower pH values indicate acidity. Theory suggests that the pH of rain varies among rainy days according to a normal distribution with a mean of 5.4 and a standard deviation of 0.5. The random sample of 21 days gives a sample standard deviation of 0.8. You would like to test if the population standard deviation is indeed 0.5 as the theory suggests. At alpha equals 0.05, what is the test statistic and what are the critical values? The test statistic: 53.76. Critical values: 9.591 and 34.170. The test statistic: 53.76. Critical values: 10.283 and 35.479. The test statistic: 51.20. Critical values: 10.283 and 35.479. The test statistic: 51.20. Critical values: 9.591 and 34.170.
Answers
The main answer to the question is: The test statistic is 51.20 and the critical values are 9.591 and 34.170.
To explain the main answer, we are conducting a hypothesis test to determine if the population standard deviation of the pH of rain is indeed 0.5, as suggested by the theory. The null hypothesis (H0) is that the population standard deviation is 0.5, while the alternative hypothesis (H1) is that the population standard deviation is not 0.5.
In this case, we are given a random sample of 21 rainy days, and the sample standard deviation is 0.8. To test the hypothesis, we need to calculate the test statistic, which is given by the formula: test statistic = [(sample standard deviation) - (hypothesized standard deviation)] / (sample standard deviation / sqrt(sample size)).
Plugging in the values, we get: test statistic = [(0.8 - 0.5) / (0.8 / sqrt(21))] = 51.20.
To determine the critical values, we need to look at the critical region associated with the given significance level (alpha) of 0.05. Since this is a two-tailed test, we divide the significance level by 2, resulting in an alpha of 0.025 for each tail. Using the degrees of freedom (n-1), which is 20 in this case, we can consult the t-distribution table or use a statistical software to find the critical t-values. For an alpha of 0.025 and 20 degrees of freedom, the critical t-values are approximately ±2.093.
Converting the t-values to critical values using the formula: critical value = (hypothesized standard deviation) + (t-value * (sample standard deviation / sqrt(sample size))), we get: critical values = 0.5 + (2.093 * (0.8 / sqrt(21))) = 9.591 and 0.5 - (2.093 * (0.8 / sqrt(21))) = 34.170.
Therefore, the correct answer is: The test statistic is 51.20 and the critical values are 9.591 and 34.170.

The F factor is integrated into the bacterial chromosome in all or most cells of an Hfr strain but in only a few cells in an F+ strain.
Answers
The F factor is integrated into the bacterial chromosome in all or most cells of an Hfr strain but in only a few cells in an F+ strain. Option d is correct.
Hfr strains of bacteria are different from F+ strains because the F factor is integrated into the bacterial chromosome in all or most cells of an Hfr strain but in only a few cells in an F+ strain. This means that Hfr strains are capable of transferring chromosomal genes during conjugation, while F+ strains are not.
During conjugation, the Hfr cell transfers a copy of its chromosomal DNA to the F- cell, but it is usually incomplete because the process is interrupted before the entire chromosome can be transferred. This results in a recombinant F- cell with new genes but still lacking the F factor. In contrast, an F+ cell can transfer only the F factor to an F- cell, not chromosomal genes. Thus, Hfr strains are an important tool for mapping bacterial chromosomes and studying gene transfer. Hence Option d is correct.

There are 120.0 mL of O2 at 700. 0 mmHg and 15⁰ C. What is the number of grams present?
Answers
Answer:
0.1498 g of O2.
Explanation:
The Behavior of Gases => Ideal Gas Law.
The ideal gas law is a single equation that relates the pressure, volume, temperature, and the number of moles of an ideal gas, which is:
\(PV=nRT,\)where P is pressure in atm, V is the volume in liters, n is the number of moles, R is the ideal gas constant (0.082 L*atm/mol*K), and T is the temperature in the Kelvin scale.
So we have to convert pressure from 700.0 mmHg to atm, volume from 120.0 mL to L, and 15 °C to K.
Let's convert pressure taking into account that 1 atm equals 760 mmHg, like this:
\(700.0\text{ mmHg}\cdot\frac{1\text{ atm}}{760\text{ mmHg}}=0.9211\text{ atm.}\)Remember that 1 L equals 1000 mL, so 120.0 mL would be equal:
\(120.0\text{ mL}\cdot\frac{1\text{ L}}{1000\text{ mL}}=0.1200\text{ L.}\)And the conversion from °C to K is just sum °C with 273, so 15 °C in K is:
\(K=\degree C+273=15\degree C+273=288\text{ K.}\)Finally, we can use the ideal gas formula, solving for 'n' (number of moles) and replacing the data that we have, as follows:
\(\begin{gathered} n=\frac{PV}{RT}, \\ \\ n=\frac{0.9211\text{ atm}\cdot0.1200\text{ L}}{0.082\frac{L\cdot atm}{mol\cdot K}\cdot288\text{ K}}, \\ \\ n=4.680\cdot10^{-3}\text{ moles.} \end{gathered}\)Now, the final step is to convert 4.680 x 10⁻³ moles of O2 to grams using the molar mass of O2 that can be calculated using the periodic table, which is 32 g/mol. The conversion will look like this:
\(4.68\cdot10^{-3\text{ }}moles\text{ O}_2\cdot\frac{32\text{ g O}_2}{1\text{ mol O}_2}=0.1498\text{ g O}_2.\)The answer would be that there are 0.1498 g of O2.

Answers
A molecule is made up of two or more atoms held together by chemical bonds in a stable association. The atoms may or may not belong to the same element
Molecules refer to groups of two or more atoms that are held together by chemical bonds in a stable association. This bond is formed when the electrons that orbit the atoms' nucleus intermingle. As a result, the atoms' outermost shells fill up with electrons, providing stability to the molecule. The atoms in a molecule may belong to the same element or to different elements.
When they belong to different elements, the molecule formed is called a compound molecule. For example, carbon dioxide (CO₂) is a compound molecule that consists of one carbon atom and two oxygen atoms. The bond between these atoms is formed because the carbon atom requires two more electrons to fill its outer shell while the oxygen atoms require two electrons each to fill their outer shells, resulting in a stable molecule.
Therefore, a molecule is made up of two or more atoms held together by chemical bonds in a stable association. The atoms may or may not belong to the same element.

Using dimensional analysis, the volume that would be required to reach the second endpoint for a HCl and sodium carbonate titration that has a known HCl concentration of 0.1700 M and a known mass of 0.1854 g of sodium carbonate is 14.00 mL.
Given:HCl concentration = 0.1700 MMass of sodium carbonate = 0.1854 gThe balanced chemical equation for the reaction between hydrochloric acid (HCl) and sodium carbonate (Na2CO3) is as follows:2HCl + Na2CO3 → 2NaCl + CO2 + H2OThe reaction is a double displacement reaction where the H+ ions in the HCl react with the CO32- ions in the Na2CO3 to form H2O and CO2. The reaction continues until all of the CO32- ions have reacted with H+ ions.At the equivalence point of the titration, the number of moles of H+ ions is equal to the number of moles of CO32- ions.
Number of moles of Na2CO3 = mass/molar mass = 0.1854 g/105.99 g/mol = 0.001750 molesAccording to the balanced chemical equation, 2 moles of HCl react with 1 mole of Na2CO3.Number of moles of HCl required = 2 × 0.001750 moles = 0.00350 molesMolarity of HCl = moles of HCl/volume of HCl in litersRearranging this equation, we get:Volume of HCl in liters = moles of HCl/molarity of HClVolume of HCl in liters required to react with sodium carbonate = 0.00350 moles/0.1700 M = 0.0206 L = 20.6 mLAt the second endpoint, all of the H+ ions have reacted with the CO32- ions, and there is an excess of H+ ions in the solution.

What neutral atom has a nuclear charge of +9, and a nuclear mass of 19 amu? How many neutrons does it have. How many electrons does it have ?
Answers
The neutral atom with a nuclear charge of +9 and a nuclear mass of 19 amu is fluorine-19. It has 10 neutrons and 9 electrons.
The atomic number of an element is equal to the number of protons in its nucleus. Therefore, if an atom has a nuclear charge of +9, it means it has 9 protons. The nuclear mass of an atom is the sum of its protons and neutrons. Since we know the nuclear mass of this atom is 19 amu, and it has 9 protons, it must have 10 neutrons (19 - 9 = 10).
To determine the number of electrons, we need to know the charge of the atom. Since it is a neutral atom, it has no net charge. This means the number of electrons must be equal to the number of protons, which is 9.
Therefore, the identity of the neutral atom is fluorine-19, with 9 protons, 10 neutrons, and 9 electrons.

Predict the change in enthalpy due to the combustion of 10 g of propane used in a camp stove. The molar enthalpy of combustion of propane is -2043. 9 kj/mol
Answers
To predict the change in enthalpy due to the combustion of propane, we need to use the given molar enthalpy of combustion and convert the mass of propane to moles.
Given:
Mass of propane = 10 g
Molar enthalpy of combustion of propane = -2043.9 kJ/mol
To calculate the moles of propane:
Molar mass of propane (C3H8) = 3 * 12.01 g/mol (3 carbon atoms) + 8 * 1.01 g/mol (8 hydrogen atoms)
Molar mass of propane = 44.11 g/mol
Number of moles of propane = Mass of propane / Molar mass of propane
Number of moles of propane = 10 g / 44.11 g/mol
Number of moles of propane ≈ 0.226 mol
Now, we can calculate the change in enthalpy using the moles of propane:
Change in enthalpy = Number of moles of propane * Molar enthalpy of combustion of propane
Change in enthalpy = 0.226 mol * -2043.9 kJ/mol
Change in enthalpy ≈ -462.19 kJ
Therefore, the change in enthalpy due to the combustion of 10 g of propane is approximately -462.19 kJ. The negative sign indicates an exothermic reaction, meaning that heat is released during the combustion process.
