To determine the mass of water formed in the reaction and compare it to the mass of oxygen and hydrogen that react, we first need to calculate the molar mass of each substance involved.
The molar mass of hydrogen (H2) is 2 grams/mol, and since there are two hydrogen molecules in the balanced equation, the total mass of hydrogen is 4 grams.
The molar mass of oxygen (O2) is 32 grams/mol, so the total mass of oxygen is 32 grams.
Now, considering the balanced equation 2 H2 + O2 -> 2 H2O, we see that two moles of hydrogen react with one mole of oxygen to produce two moles of water.
Using the molar masses we calculated earlier, we know that two moles of hydrogen have a mass of 4 grams, and one mole of oxygen has a mass of 32 grams. Therefore, the total mass of the reactants (hydrogen and oxygen) is 4 grams + 32 grams = 36 grams.
Since the equation states that two moles of water are formed, we can determine its mass by multiplying the molar mass of water (18 grams/mol) by 2. Therefore, the mass of the water formed is 36 grams.
So, in this reaction, the mass of water formed (36 grams) is equal to the mass of oxygen and hydrogen that react (36 grams). This demonstrates the law of conservation of matter, which states that matter cannot be created or destroyed in a chemical reaction.
Now, let's explain the production of water in the reaction. When hydrogen (H2) and oxygen (O2) combine, they react to form water (H2O). This is an example of a synthesis reaction, where two or more substances combine to form a new, more complex substance. In this case, the hydrogen and oxygen molecules combine to form water molecules.
The balanced equation shows that two moles of hydrogen react with one mole of oxygen to produce two moles of water. The coefficients in the balanced equation indicate the ratio in which the substances react and form products. Therefore, for every 2 grams of hydrogen and 32 grams of oxygen, we will get 36 grams of water.
To summarize, the mass of water formed in the reaction is equal to the mass of oxygen and hydrogen that react because of the law of conservation of matter. The balanced equation represents the types of changes occurring in the reaction, and in this case, it is a synthesis reaction. The production of water involves the combination of hydrogen and oxygen molecules to form water molecules.
