Question

Hydrogen and oxygen react under a specific

set of conditions to produce water according
to the equation
2 H2(g) + O2(g) −→ 2 H2O(g).
How much hydrogen would be required to
produce 8 mol of water?
1. 6.5

2. 5.8

3. 2.8

4. 9.9

5. 6.8

6. 5.5

7. 8

8. 3.7

9. 8.9

10. 9.1

Answer 1

The answer to your question is 3 moles

Step-by-step explanation:

Data

moles of hydrogen = ?

moles of water = 3

Chemical reaction

2H₂ + O₂ ⇒ 2 H₂O

To answer this question we can use proportions and the coefficients of each molecule.

2 moles of Hydrogen ------------------- 2 moles of water

x ------------------- 3 moles of water

x = (3 x 2)/2

x = 6/2

x = 3 moles of hydrogen

HOPE THIS HELPS YOU!!!!!!!!!
