The two types of energy changes that occur are heat and light changes.
0.02 mol NaCl
Explanation:
(0.2M NaCl)×(0.10 L) = 0.02 mol NaCl
Sandblasted: More smooth because all the rough edges are "blasted" away. And slightly smaller because of the loss of the edges.
Non-Sandblasted: Not smooth; rough.
1×10^-4 = 0,0001M
pH = -log[H+]
pH = -log0,0001
pH = 4
Hess's Law of Constant Heat Summation (or just Hess's Law) states that regardless of the multiple stages or steps of a reaction, the total enthalpy change for the reaction is the sum of all changes. This law is a manifestation that enthalpy is a state function.
