2H2 + O2 = 2H2O.

The combustion of methane, CH4, releases 890.4 kJ/mol. That is, when one mole of methane is burned, 890.4 kJ are given off to the surroundings. This means that the products have 890.4 kJ less than the reactants.

Combustion of one mole or 16 g of methane gas releases 810 kJ of heat energy. Thus, heat released by the combustion of 22.4 g of methane is 1134 kJ.

Combustion of a substance is its reaction with atmospheric oxygen producing carbon dioxide and water. Combustion of hydrocarbons gases takes places easily and can be burned easily for fuels.

The chemical equation of combustion of methane is written below:

\(\rm CH_{4} + 2O_{2} \rightarrow CO_{2} + 2H_{2}O\)

This is an exothermic process and heat is released from the reaction system.

The heat released by the combustion of one mole of methane is 810 kJ.

molar mass of methane = 16 g/mol

no.of moles in 22.4 g = 22.4/16 = 1.4 g

Thus, heat released by 1.4 moles = 1.4 ×810 kJ =1134 kJ.

Answer:

Group 17/VIIA

Highly reactive

7 electrons in their outer shell

They become stable and have noble gas configurations when they gain one more electron from metal

Explanation:

halogen, any of the six nonmetallic elements that constitute Group 17 (Group VIIa) of the periodic table. The halogen elements are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts).

Due to their high effective nuclear charge, halogens are highly electronegative. Therefore, they are highly reactive and can gain an electron through reaction with other elements.

Halogens are very reactive because they have seven valence electrons and need one more to have eight valence electrons (an octet). They react with metals and other halogens to get an octet. When this happens, the atoms become stable and have noble gas configurations.

The effects of supercritical CO2 (SC-CO2) on the microbiological, sensory (taste, odour, and colour), nutritional (vitamin C content), and physical (cloud, total acidity, pH, and °Brix) qualities of orange juice were studied. The CO2 treatment was performed in a 1 litre capacity double-walled reactor equipped with a magnetic stirring system. Freshly extracted orange juice was treated with supercritical CO2, pasteurised at 90°C, or left untreated. There were no significant differences in the sensory attributes and physical qualities between the CO2 treated juice and freshly extracted juice. The CO2 treated juice retained 88% of its vitamin C, while the pasteurised juice was notably different from the fresh juice and preserved only 57% of its vitamin C content. After 8 weeks of storage at 4°C, there was no microbial growth in the CO2 treated juice.

Explanation:

Polar bonds do not always result in polar molecules; for example, carbon dioxide has polar bonds but is a nonpolar molecule because its bond polarities cancel out due to its linear geometry.

The statement that all molecules with polar bonds are polar molecules is not entirely correct. While it is true that polar bonds occur between atoms with different electronegativities, giving rise to partial positive and negative charges within the molecule, a molecule can still be nonpolar if the polar bonds cancel out each other's effects.

For example, carbon dioxide has two polar bonds between the carbon atom and each oxygen atom, but the molecule is nonpolar because the arrangement of the atoms is linear, with the polar bonds facing in opposite directions and canceling each other's effect. Similarly, tetrachloromethane has four polar bonds between the carbon atom and each chlorine atom, but the molecule is nonpolar due to its tetrahedral geometry, which results in the polar bonds being arranged symmetrically around the carbon atom.

Therefore, it is essential to consider both the electronegativity difference and the geometry of the molecule to determine whether a molecule is polar or nonpolar.

The mass of potassium hydroxide required to neutralize 0.955 moles of sulfuric acid is 107.08 grams.

The balanced equation you provided is for the reaction of potassium hydroxide with sulfur dioxide, not sulfuric acid. The correct equation is:

2KOH(aq) + H2SO4(aq) → K2SO4(aq) + 2H2O(l)

To find the mass of potassium hydroxide required to neutralize 0.955 moles of sulfuric acid, you can use the mole ratio between potassium hydroxide and sulfuric acid in the balanced equation, which is 2:1. That means you need twice as many moles of potassium hydroxide as sulfuric acid to completely neutralize it.

So, the number of moles of potassium hydroxide required is 2 x 0.955 = 1.91 moles.

To calculate the mass of potassium hydroxide required, you can use its molar mass, which is 56.11 g/mol:

mass = number of moles x molar mass

mass = 1.91 moles x 56.11 g/mol

mass = 107.08 g

The wavelength of a radio wave with a frequency of 95 x 10^6 Hz can be calculated using the formula:

wavelength = speed of light / frequency

The speed of light is approximately 3 x 10^8 m/s. Substituting the given values:

wavelength = (3 x 10^8 m/s) / (95 x 10^6 Hz)

wavelength ≈ 3.16 m (rounded to 2 significant figures)

Therefore, the wavelength of the radio wave is approximately 3.16 meters.

b)

The molarity (M) of a solution can be calculated using the formula:

Molarity = moles of solute / liters of solution

Substituting the given values:

Molarity = 0.44 mol / 1.12 L

Molarity ≈ 0.39 M (rounded to 2 significant figures)

Therefore, the molarity of the solution is approximately 0.39 M.

We need 9.05 mL of the 0.348 M hydroiodic acid solution to neutralize 13.2 mL of the 0.119 M barium hydroxide solution.

To solve this problem, we will use the balanced chemical equation for the reaction between hydroiodic acid (HI) and barium hydroxide (Ba(OH)2):
2HI + Ba(OH)2 → BaI2 + 2H2O
We can see from this equation that two moles of hydroiodic acid are required to neutralize one mole of barium hydroxide. Therefore, we need to calculate the number of moles of barium hydroxide present in the 13.2 mL of 0.119 M solution:
moles of Ba(OH)2 = volume (in L) x concentration (in mol/L)
moles of Ba(OH)2 = 13.2 mL x (1 L/1000 mL) x 0.119 mol/L
moles of Ba(OH)2 = 0.00157 mol
Since two moles of hydroiodic acid are required to neutralize one mole of barium hydroxide, we need twice as many moles of hydroiodic acid as moles of barium hydroxide:
moles of HI = 2 x moles of Ba(OH)2
moles of HI = 2 x 0.00157 mol
moles of HI = 0.00314 mol
Finally, we can use the concentration of the hydroiodic acid solution to calculate the volume required:
moles of HI = volume (in L) x concentration (in mol/L)
volume (in L) = moles of HI / concentration (in mol/L)
volume (in L) = 0.00314 mol / 0.348 mol/L
volume (in L) = 0.00905 L

The equilibrium constant (K) for the isomerization of glucose-1-phosphate to fructose-6-phosphate at 298 Kelvin is 3.35.

To calculate the equilibrium constant (K), we can use the following formula:

K = e^(-ΔG / (RT))

Where ΔG is the Gibbs free energy change (-5.61 kJ/mol), R is the gas constant (8.314 J/mol K), and T is the temperature (298 K).

First, convert ΔG to J/mol: -5.61 kJ/mol * 1000 J/kJ = -5610 J/mol

Then, plug the values into the formula:

K = e^(-(-5610) / (8.314 * 298))

K = e^(5610 / 2476.972)

K = e^2.263

K = 3.35 (rounded to two decimal places)

The equilibrium constant (K) for the isomerization of glucose-1-phosphate to fructose-6-phosphate at a temperature of 298 Kelvin is 3.35.

Answer:

The molar concentration of a 12% sodium chloride solution is approximately 2.05 M.

To determine the molar concentration of a 12% sodium chloride solution, we need to convert the given percentage concentration into molarity.

First, we need to understand that the percentage concentration refers to the mass of the solute (sodium chloride) relative to the total mass of the solution.

In this case, a 12% sodium chloride solution means that there are 12 grams of sodium chloride in 100 grams of the solution.

To convert this into molar concentration, we need to consider the molar mass of sodium chloride, which is 58.5 g/mol.

We can start by calculating the number of moles of sodium chloride in 12 grams:

Moles of sodium chloride = mass of sodium chloride / molar mass of sodium chloride

Moles of sodium chloride = 12 g / 58.5 g/mol = 0.205 moles

Next, we calculate the volume of the solution in liters using the density of the solution. Since the density is not provided, we assume a density of 1 g/mL for simplicity:

Volume of solution = mass of solution / density

Volume of solution = 100 g / 1 g/mL = 100 mL = 0.1 L

Finally, we calculate the molar concentration (Molarity) by dividing the number of moles by the volume in liters:

Molar concentration = moles of solute / volume of solution

Molar concentration = 0.205 moles / 0.1 L = 2.05 M

Therefore, the molar concentration of a 12% sodium chloride solution is approximately 2.05 M.
