How many moles of H2O will be formed from the reaction of 80 g of
NaOH? *
H2SO4 + 2 NaOH = Na2SO4 + 2 H 0

0.5 moles
1 mole
2 moles
4 moles

2 moles of will be formed.

Explanation:

To calculate the moles :

The balanced chemical equation is:

According to stoichiometry :

2 moles of give = 2 moles of

Thus 2 moles of give = of

Thus 2 moles of will be formed.

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).

your answer would be “dry”
