The Equation of Hydrogen and Oxygen Reaction: Understanding the Production of Water

Chemical reactions are the foundation of chemistry, and understanding the stoichiometry of these reactions is crucial in determining the amount of products formed. In this article, we will focus on the reaction between hydrogen and oxygen to produce water, as shown in the equation below:

2H2+O2→2H2O2 H_2 + O_2 \rightarrow 2 H_2O

This equation indicates that 2 moles of hydrogen gas react with 1 mole of oxygen gas to produce 2 moles of water. In this article, we will explore how many moles of water would be produced if 16 moles of oxygen were reacted with excess hydrogen gas.

The reaction between hydrogen and oxygen is a classic example of a combustion reaction. In this reaction, hydrogen gas reacts with oxygen gas to produce water and heat energy. The balanced equation for this reaction is:

2H2+O2→2H2O2 H_2 + O_2 \rightarrow 2 H_2O

From this equation, we can see that 2 moles of hydrogen gas react with 1 mole of oxygen gas to produce 2 moles of water. This means that the ratio of hydrogen gas to oxygen gas to water is 2:1:2.

Now that we have understood the reaction, let's determine how many moles of water would be produced if 16 moles of oxygen were reacted with excess hydrogen gas. To do this, we need to use the concept of stoichiometry.

Stoichiometry is the branch of chemistry that deals with the quantitative relationships between reactants and products in chemical reactions. In this case, we need to use the mole ratio of oxygen gas to water to determine the number of moles of water produced.

From the balanced equation, we can see that 1 mole of oxygen gas produces 2 moles of water. Therefore, if 16 moles of oxygen gas are reacted, the number of moles of water produced can be calculated as follows:

Number of moles of water produced = (Number of moles of oxygen gas) x (Mole ratio of oxygen gas to water) = 16 mol x 2 = 32 mol

However, we need to consider the fact that the question states that excess hydrogen gas is present. This means that the reaction will proceed until all the oxygen gas is consumed, and the hydrogen gas will be in excess. Therefore, the number of moles of water produced will be equal to the number of moles of oxygen gas reacted.

In conclusion, if 16 moles of oxygen were reacted with excess hydrogen gas, the number of moles of water produced would be equal to the number of moles of oxygen gas reacted, which is 16 moles.

The correct answer is C. 16 mol.

This problem requires a good understanding of the concept of stoichiometry and the mole ratio of reactants and products in chemical reactions. It also requires the ability to apply this concept to a specific problem and calculate the number of moles of products formed.

    Q&A: Understanding the Equation of Hydrogen and Oxygen Reaction

In our previous article, we explored the reaction between hydrogen and oxygen to produce water, as shown in the equation below:

2H2+O2→2H2O2 H_2 + O_2 \rightarrow 2 H_2O

We also determined that if 16 moles of oxygen were reacted with excess hydrogen gas, the number of moles of water produced would be equal to the number of moles of oxygen gas reacted, which is 16 moles.

In this article, we will provide a Q&A section to help you better understand the concept of stoichiometry and the mole ratio of reactants and products in chemical reactions.

Q1: What is the mole ratio of hydrogen gas to oxygen gas to water in the reaction?

A1: The mole ratio of hydrogen gas to oxygen gas to water is 2:1:2.

Q2: If 8 moles of hydrogen gas were reacted with excess oxygen gas, how many moles of water would be produced?

A2: To determine the number of moles of water produced, we need to use the concept of stoichiometry. From the balanced equation, we can see that 2 moles of hydrogen gas react with 1 mole of oxygen gas to produce 2 moles of water. Therefore, if 8 moles of hydrogen gas are reacted, the number of moles of water produced can be calculated as follows:

Number of moles of water produced = (Number of moles of hydrogen gas) x (Mole ratio of hydrogen gas to water) = 8 mol x 1 = 8 mol

Q3: If 32 moles of oxygen gas were reacted with excess hydrogen gas, how many moles of water would be produced?

A3: To determine the number of moles of water produced, we need to use the concept of stoichiometry. From the balanced equation, we can see that 1 mole of oxygen gas produces 2 moles of water. Therefore, if 32 moles of oxygen gas are reacted, the number of moles of water produced can be calculated as follows:

Number of moles of water produced = (Number of moles of oxygen gas) x (Mole ratio of oxygen gas to water) = 32 mol x 2 = 64 mol

Q4: If 64 moles of hydrogen gas were reacted with excess oxygen gas, how many moles of water would be produced?

A4: To determine the number of moles of water produced, we need to use the concept of stoichiometry. From the balanced equation, we can see that 2 moles of hydrogen gas react with 1 mole of oxygen gas to produce 2 moles of water. Therefore, if 64 moles of hydrogen gas are reacted, the number of moles of water produced can be calculated as follows:

Number of moles of water produced = (Number of moles of hydrogen gas) x (Mole ratio of hydrogen gas to water) = 64 mol x 1 = 32 mol

Q5: What is the significance of excess hydrogen gas in the reaction?

A5: The presence of excess hydrogen gas in the reaction means that the reaction will proceed until all the oxygen gas is consumed, and the hydrogen gas will be in excess. This is important because it allows us to determine the number of moles of water produced by using the concept of stoichiometry.

In conclusion, the Q&A section provided in this article is designed to help you better understand the concept of stoichiometry and the mole ratio of reactants and products in chemical reactions.
