How many moles of water are produced when 5 moles of hydrogen gas react with 2 moles of oxygen gas? 2 moles of water 4 moles of water 5 moles of water 7 moles of water

Option (b) is the correct answer.

Explanation:

As it can be seen from the chemical equation, 2 moles of hydrogen reacts with 1 mole of oxygen.

Therefore, 2 moles of oxygen will react with 4 moles of hydrogen. So, oxygen is the limiting reagent and hydrogen is the excess reagent. Therefore, the reaction equation will be as follows.

Thus, we can conclude that 4 moles of water are produced when 5 moles of hydrogen gas react with 2 moles of oxygen gas.

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8
