What is the molarity of 6 moles (mol) of NaCl dissolved in 2 L of water? O A.
2 mol
6L
ОВ.
6L
2 mol
O c.
6 mol
2L
O D.
2L
6 mol

C:  

Explanation:

we can use the molarity equation

so to find M we plug in what we know, which is 6 moles of NaCl and 2 L of water, which gives us:

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
