8. Hydrogen and oxygen gas combine explosively to produce water. Write a balanced chemical equation for this process. If 10 mol of hydrogen reacted with oxygen, what volume of liquid water could be produced?

2H2(g) + O2(g) ==> 2H2O(l)

10 moles H2 will combine with 5 moles of O2 to produce 10 moles liquid water. All of that comes from the equation. How many grams will 10 moles water be? One mole is 18.015 g; therefore, 10 moles must be 180.15 g. If the density of the liquid water is 1.00 g/mL and mass = volume x density, the volume of the water will be ?? mL.

To write a balanced chemical equation for the combination of hydrogen and oxygen gas to produce water, we need to first know the chemical formulas for hydrogen gas (H2) and oxygen gas (O2), as well as the formula for water (H2O).

The chemical equation can be written as:
2H2 + O2 -> 2H2O

In this equation, there are two molecules of hydrogen gas (H2) and one molecule of oxygen gas (O2) on the left-hand side, which react to form two molecules of water (H2O) on the right-hand side.

To calculate the volume of liquid water produced when 10 mol of hydrogen reacts with oxygen, we need to use the concept of stoichiometry, which is the relationship between the amounts of reactants and products in a chemical reaction.

From the balanced equation, we can see that 2 moles of H2 react with 1 mole of O2 to produce 2 moles of H2O.

Therefore, the molar ratio between H2 and H2O is 2:2 or 1:1.

Since we have 10 mol of hydrogen (H2), we can conclude that 10 mol of water (H2O) will be produced.

Now, to find the volume of liquid water produced, we need to know the relationship between moles and volume. This can be determined using the molar volume of a gas at standard temperature and pressure (STP).

At STP, 1 mol of any gas occupies 22.4 liters of volume.

Therefore, if we assume that the gaseous reactants and products occupy the same volume, we can say that 10 mol of water (H2O) would occupy 10 * 22.4 = 224 liters of volume.

Hence, if 10 mol of hydrogen reacted with oxygen, the volume of liquid water produced would be approximately 224 liters.
