Density of liquid= 
.
so, density of liquid= 
= 1.2 gm/cm³.
Answer:
a. CH3COO⁻.
Explanation:
Hello there!
In this case, according to the given ionization reaction of acetic acid:
CH₃COOH + H₂O --> H₃O⁺ + CH₃COO⁻
Whereas we can evidence how the CH₃COOH is the acid whereas H₂O the base, as the former donates H ions to the latter, which accepts them; we can infer that H₃O⁺ is the conjugate acid, resulting from the base and the a. CH3COO⁻ is the conjugate base, resulting from the acid.

Global cooling was a hypothesis of the looming cooling of the Earth's surface and atmosphere that would take place over a period of substantial glaciation.
It emerged as a result of a drop of temperature during the period of 1940s and 1970s. After this it was realized that it is not a big threat as global warming.
On the other hand, Global warming is the rise in overall temperature of the atmosphere which is caused by greenhouse effect that is as a result of rise in the levels of greenhouse gas emissions such as CFCs and carbon dioxide.
Global warming is a present threat in the society world over with the rise in temperatures and climatic changes taking place, this is the reason why global warming replaced global cooling.
Hello, Brainly User!
As the planet gets warmer, sea level rises for two reasons. First, warmer temperatures cause ice on land like glaciers and ice sheets to melt, and the melt water flows into the ocean to increase sea level. Second, warm water expands and takes up more space than colder water, increasing the volume of water in the sea.
