Question

How many grams of H₂ would be formed if 34 grams of carbon reacted with an unlimited amount of H₂O? The reaction is:

C + H₂O → CO + H₂
The atomic mass of C is 12.01 g/mole. The atomic mass of H₂ is 2.016 g/mole. Finish the problem by choosing the correct format for dimensional analysis.

Answer 1

To find the amount of H₂ formed from 34 grams of carbon, we calculate the moles of carbon, and using the molar mass of H₂ and the stoichiometry of the reaction, we find that 5.706 grams of H₂ would be produced.

Step-by-step explanation:

To determine the amount of H₂ formed when 34 grams of carbon reacts with an unlimited amount of H₂O, we use stoichiometry and dimensional analysis. First, we calculate the moles of carbon using its molar mass:

34 g C × (1 mol C / 12.01 g C) = 2.831 moles of C

According to the balanced chemical reaction, 1 mole of C reacts to form 1 mole of H₂, which means 2.831 moles of C would produce 2.831 moles of H₂:

2.831 moles H₂ × (2.016 g H₂ / 1 mol H₂) = 5.706 g H₂

Therefore, 5.706 grams of H₂ would be produced.
