The following equation shows the formation of water from hydrogen and oxygen.
2H2 + O2 → 2H2O
How many grams of water will form if 10.54 g H2 reacts with 95.10 g O2
Which reactant is the limiting reactant?
Answers
As per the given data, approximately 94.17 grams of water will form when 10.54 g of \(H_2\) reacts with 95.10 g of \(O_2\), and \(H_2\) is the limiting reactant.
To determine the limiting reactant, we need to compare the amounts of each reactant and their respective stoichiometric coefficients in the balanced equation.
Given:
Mass of \(H_2\) = 10.54 g
Mass of \(O_2\) = 95.10 g
First, we need to convert the masses of \(H_2\) and \(O_2\) to moles using their molar masses:
Molar mass of \(H_2\) = 2.016 g/mol
Molar mass of \(O_2\) = 31.9988 g/mol
Number of moles of \(H_2\) = 10.54 g / 2.016 g/mol ≈ 5.229 mol
Number of moles of \(O_2\) = 95.10 g / 31.9988 g/mol ≈ 2.972 mol
Now, let's compare the moles of \(H_2\) and \(O_2\) to their stoichiometric coefficients in the balanced equation:
\(2H_2 + O_2 --- > 2H_2O\)
From the balanced equation, we can see that the stoichiometric ratio is 2:1 for \(H_2\) to \(O_2\). This means that 2 moles of \(H_2\) react with 1 mole of \(O_2\) to produce 2 moles of \(H_2O\).
Based on the stoichiometric ratio, we can calculate the maximum amount of water that can be formed from the given amounts of H2 and O2.
The moles of water formed will be limited by the reactant that produces fewer moles of water. From the stoichiometry, we know that 2 moles of H2 react to produce 2 moles of H2O.
Number of moles of water that can be formed from H2 = 2.229 mol × (2 mol H2O / 2 mol H2) = 5.229 mol
Number of moles of water that can be formed from O2 = 2.972 mol × (2 mol H2O / 1 mol O2) = 5.944 mol
Since the number of moles of water that can be formed from H2 (5.229 mol) is less than the number of moles that can be formed from O2 (5.944 mol), H2 is the limiting reactant.
To find the mass of water formed, we need to multiply the number of moles of water by its molar mass:
Molar mass of H2O = 18.015 g/mol
Mass of water formed from H2 = 5.229 mol × 18.015 g/mol ≈ 94.17 g
Therefore, approximately 94.17 grams of water will form when 10.54 g of H2 reacts with 95.10 g of O2, and H2 is the limiting reactant.

A student produced 1.06 g of NH3 from the reaction of 1.77 g of H2 with 25.7g N2 gas.
N2 + 3H2 → 2NH3
Theoretical yield?
Percent yield?
Answers
The theoretical yield of NH3 is 10.03 g and percent yield is 10.56%
What is the theoretical yield?The theoretical yield is obtained from the eequation if reaction.
The equation of the reaction is given below:
N2 + 3H2 → 2NH3moles of reactants and products:
moles of H2 = 1.77/2 = 0.885 moles
moles of N2 = 25.7/28 = 0.918 moles
moles of NH3 = 1.06/17 = 0.062
From the equation of the reaction, H2 is the limiting reactant
3 moles of H2 produces 2 moles of NH3
0.885 moles of H2 will produce 2/3 × 0.918 = 0.59 moles of NH3
Therefore:
theoretical yield = 0.59 × 17
theoreticalyield = 10.03 g of NH3
Percent yield = 1.06/10.03 × 100%
percent yield = 10.56%

Answers
The temperature reading on Fahrenheit scale is related to the The temperature reading on Celsius scale by a linear equation F = 9/5 C + 32
Data for Fahrenheit temperature scale:
Water freezing point = 32⁰
Water boiling point = 212⁰
Therefore, the scale is divided into 212 - 32 = 180 scales.
Data for Celsius temperature scale:
Water freezing point = 0⁰
Water boiling point = 100⁰
Therefore, the scale is divided into 100 - 0 = 100 scales.
Scale ratio:
C : F = 100 : 180 = 5 : 9
It means each increment of 1⁰ on Celsius scale is equal to an increment of 9/5 degree on Fahrenheit scale. However, we need to add an offset 32⁰ on Fahrenheit scale.
Hence, the reading C⁰ on Celsius scale is equivalent to:
F = 9/5 C + 32

while hydrogen, helium, water, and ammonia can produce the white coloration of jupiter's zones, the brownish color of the belts requires more complex chemistry. group of answer choices
Answers
The white coloration in Jupiter's zones is attributed to hydrogen, helium, water, and ammonia, while the brownish color in the belts involves more intricate chemical processes.
Jupiter's distinct coloration is the result of its complex atmospheric composition. The planet's zones, characterized by their white appearance, are primarily composed of hydrogen and helium, the most abundant elements in its atmosphere.
Additionally, water and ammonia play a role in producing white coloration by contributing to the formation of clouds and condensation. These compounds reflect sunlight, creating the bright zones observed on Jupiter's surface.
However, the belts on Jupiter exhibit a different coloration, appearing brownish in comparison to the zones. The brown hue is attributed to the presence of more complex chemical reactions occurring within the atmosphere.
Scientists believe that the belts contain compounds such as phosphorus, sulfur, and carbon, which interact with solar radiation and atmospheric conditions to produce a distinctive brown color. These compounds likely arise from the planet's lower atmosphere and may be the result of processes such as upwelling or vertical mixing.
The exact mechanisms responsible for the belts' brown coloration are still under investigation, and further research is necessary to fully understand the intricate chemistry behind Jupiter's atmospheric colors.

Describe the feedback loop involving water vapor and temperature. Is it positive or negative?
Answers
Answer:
The feedback loop involving water vapor and temperature is a positive feedback loop. As temperature increases, the amount of water vapor that can be held in the atmosphere also increases. This leads to an increase in the amount of water vapor in the atmosphere, which further amplifies the greenhouse effect and contributes to additional warming.
In other words, warmer temperatures lead to more water vapor in the atmosphere, which traps more heat, causing further warming, and so on. This positive feedback loop can amplify the initial warming effect caused by other factors such as greenhouse gas emissions or changes in solar radiation.
Conversely, if the temperature decreases, the amount of water vapor that can be held in the atmosphere decreases, which can lead to a decrease in the amount of water vapor present in the atmosphere, reducing the greenhouse effect and contributing to cooling. However, this negative feedback loop is weaker than the positive feedback loop described above, and it tends to be dominated by the positive feedback loop under most circumstances.

Answers
The difference in degrees Fahrenheit between the maximum expected temperatures by the end of the century between the lower and higher emissions scenarios can vary depending on various factors and assumptions.
However, in general, the lower emissions scenario is expected to result in a lower increase in global temperatures compared to the higher emissions scenario.
This means that the maximum expected temperature rise by the end of the century under the lower emissions scenario would be lower than that of the higher emissions scenario.
The specific temperature difference would depend on the specific projections and models used, but it highlights the significant impact that emissions reductions can have on mitigating future temperature increases.

The correct IUPAC name for the compound is 5-bromo-1,3-cyclohexadiene.
This is because the bromine atom is attached to the 5th carbon atom in the cyclohexadiene ring. The double bonds are also located between the 1st and 2nd carbon atoms and the 3rd and 4th carbon atoms, hence the "1,3" in the name.
