Vinegar (acetic acid) in a solution will react with chalk (calcium carbonate) a solid. the rate of the reaction can be determined by how quickly carbon dioxide, one of the products, is produced. which solution of acetic acid will produce the highest reaction rate?

The more concentrated the solution of acetic acid, the highest the reaction rate. Thus, 12M acetic acid will react faster than 5M acetic acid. The more the amount of acetic acid solution, the highest the reaction rate. Increasing the temperature of acetic acid solution also increases the rate of reaction between acetic acid and calcium carbonate. 

Explanation:

b) returns freshwater to the earth.

c) returns freshwater to the earth.c) occurs after condensation.

d) returns freshwater to the earth.c) occurs after condensation.d) roughly equal to the amount of evaporation.

happy to

pls mark as brainliest.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
