Suppose you wanted to know how many grams of KCl would be left if 350mL of a 2.0M KCl solution were evaporated to dryness.
b. How would heating the solution affect the mass of KCl?

52.2g of KCl would be left

The mass of KCl will remain despite the solution is been heated

Explanation:

When you are heating a solution, just the solvent (In this case, water), will be evaporated and, in theory, the mass of KCl will remain despite the solution is been heated.

Now, the mass of KCl that you can obtain from 350mL of a 2.0M solution will be:

Moles KCl:

350mL = 0.350L * (2.0mol / L) = 0.700 moles

Mass KCl -Molar mass: 74.55g/mol-:

0.700mol * (74.55g/mol) = 52.2g of KCl would be left

explanation:

i think option no d is the correct answer

answer: cellular respiration takes in food and uses it to create atp, a chemical which the cell uses for energy. usually, this process uses oxygen, and is called aerobic respiration. it has four stages known as glycolysis, link reaction, the krebs cycle, and the electron transport chain.
