Answer: The molarity of the base solution is 0.22 M.
Explanation:
According to the neutralization law,
where,
= molarity of 
solution = 0.1994 M
= volume of solution = 38.87 ml
= molarity of 
solution = ?
= volume of solution = Final reading - Initial reading = 36.18 - 1.16 = 35.02 ml
= valency of = 1
= valency of = 1
Therefore, the molarity of the base solution is 0.22 M.

See explanation for details
Explanation:
6) C is false. What is going on there is actually a transformation of mechanical energy to the chemical energy stored in carbon dioxide in the atmosphere. The burning of the fossil fuel produces mechanical energy which is stored in the chemical bonds of CO2 hence the statement is false
7) A is true. Solar energy refers to energy from the sun, this energy is trapped from Tue sun and stored in chemical bonds in glucose, and starch molecules during photosynthesis.
8) C represents the release of carbon dioxide by the burning of fossil fuels.
9) B,C,D, E
B refers to photosynthesis in which plants take in atmospheric carbon dioxide
C refers to the burning of fossil rules which releases atmospheric carbon dioxide
D refers to the dissolution of atmospheric carbon dioxide in water bodies to form carbonates in water.
E refers refers the return of organic carbon to the soil by dead organisms
10) A and C
A shows the conversion of solar energy to chemical energy
C shows the conversion of mechanical energy to chemical energy
Which elements are most reactive?
The alkali metals, found in group 1 of the periodic table (formerly known as group IA), are very reactive metals that do not occur freely in nature. These metals have only one electron in their outer shell. Therefore, they are ready to lose that one electron in ionic bonding with other elements.
Fluorine is the most reactive
A. <span>Sodium is oxidized and chlorine is reduced.</span>
Explanation:
no compound there is considered an acid because this isn't a neutralization reaction ie between an acid and a base ,it didn't even form a salt
