Question

Can someone please explain this to me as simply as possible i am a little slow

Answer 1

To solve this question we need to use the reaction equation proportion.

The reaction is: 2 H2O -> 2 H2 + O2

The equation tells us that 2 moles of H2O produce 2 moles of H2 and 1 mole of O2.

So, if 2 moles of H2O produce 1 mole of O2

0.5 moles of H2O produce x mole of O2

Here we can do a rule of 3:

2 moles of H2O --- 1 mole of O2

0.5 moles of H2O --- x mole of O2

0.5 x 1 = 2x

x = 0.5/2

x = 0.25 mole

Answer: The number of moles of O2 produced is 0.25 moles.
