Answer:
chemonoia
Explanation:
Many people have a strong fear of “chemicals” that belies the evidence. It's called chemonoia – and it may be damaging their health. If you were paranoid, you might think there really was something in the water that's damaged our sense of reason.
The mass of water produced by the reaction of the 23 g of 
is 13.8 g.
The given chemical reaction;
In the given compound above, we can deduce the following;
- molecular mass of = 28 + (2 x 16) = 60 g
- molecular mass of
= 2(18) = 36 g
60 g of --------- 36 g of water
23 g of ------------- ? of water
Thus, the mass of water produced by the reaction of the 23 g of is 13.8 g.
