When 3.5 moles of sodium oxide react, how many moles of sodium hydroxide will be produced? moles NaOH *Report your answer to the
correct number of significant digits!
Na2O + H2O -> 2 NaOH

7 moles of NaOH will produced.

Explanation:

Given data:

Number of moles of sodium oxide = 3.5 mol

Number of moles of sodium hydroxide produced = ?

Solution:

Chemical equation:

Na₂O + H₂O      →     2NaOH

Now we will compare the moles of sodium oxide with sodium hydroxide.

                 Na₂O            :         NaOH      

                    1                 :             2

                  3.5               :         2/1×3.5 = 7

7 moles of NaOH will produced.

the answer is barium and copper bromide
