Answer:
The correct answer is c) polar
Explanation:
Water is a polar chemical compound, formed by the covalent bond between hydrogen and oxygen. There is an electronegative region on the part of the latter and an electropositive one on the part of hydrogen. Each molecule forms a Hydrogen Bridge junction with the oxygen atom of another nearby molecule.
According to the fact that [H+]*[OH-] is always equal Kw

, you can easily find concentration of [H+] by changing from

to

H increases, Kw is constant, therefore

And you will have
![Hence [H+] = 10^-3](https://tex.z-dn.net/?f=Hence%20%5BH%2B%5D%20%3D%2010%5E-3%20%20)
where pH is 3
Answer:
4,000 Kilojoules (2 sig. figs. based on 2 sig. figs. in 75Kg water).
Explanation:
Energy change equation => q = m·c·ΔT
q = total amount of heat flow
m = mass in grams = 75,000 grams
c = specific heat of water = 4.184 joules/gram·°C
ΔT = Temperature change in °C = 22.4°C - 9.8°C = 12.6°C
q =(75,000g)(4.184j/g·°C)(12.6°C) = 3,953,880 joules = 3,954 Kilojoules ≅ 4,000 Kilojoules (2 sig. figs. based on 2 sig. figs. in 75Kg water).
