Answer:
The reaction type is Synthesis
Hey there!
Molar mass of nitrogen is 14.007 g.
We have 7 moles.
Multiply 7 by 14.007.
7 x 14.007 = 98.049
7 moles of nitrogen has a mass of 98.049 grams.
Hope this helps!
Hydrogen + oxygen -> water
2H2 + O2 -> 2H2O (balanced)
2 moles of hydrogen gas will react with 1 mole of oxygen to produce 2 moles of water.
following that ratio, 0.734 mole of oxygen must need 0.734 × 2 moles of hydrogen to fully react.
answer is 1.468 moles of hydrogen.
