Answer:
Explanation:
Strong electrolytes completely ionize when dissolved, and no neutral molecules are formed in solution. Since NaCl is an ionic solid (s), which consists of cations Na+ and anions Cl−, no molecules of NaCl are present in NaCl solid or NaCl solution. The ionization is said to be complete.

Answer:
B. During the light reactions of photosynthesis, water is split, removing electrons and protons, and oxygen gas is released.
Explanation:
In Photosynthesis two phases occurs. They are grouped into light dependent and light independent phase (dark phase) reactions. In the light dependent phase, sunlight is trapped by chlorophyll and water is split into its components ( oxygen, hydrogen ions and free electrons; photolysis). Part of the electrons and the hydrogen ions are picked up by NADP (Nicotinamide adenine dinucleotide phosphate) converting it to NADPH and part of the electrons are used to replenished the photosystems trapping the sunlight.
Answer:
The concentration of dilute solution is 0.72M
Explanation:
According to the given question
V1=30 ml
S1 = 12 M
V2= 500 ml
then S2 =?
we all know that V1S1=V2S2
or S2= V1S1÷V2
or S2 = 30×12÷500
or S2= 360÷500
or S2 =0.72 M.
The concentration of dilute solution is 0.72 M
B) Exothermic
The reaction released heat energy to its surrounding, thus, it was exothermic.
"exo" is to expel or put outside
"thermic" means heat
