Looks like you're missing an answer choice. I have this question on my practice test for AP Chemistry, the correct answer would be KCl.
mass AgCl = 2.23 - 0.80 = 1.43g AgCl
1.43g AgCl / 143g/mol AgCl = 0.01 moles AgCl
- AgCl has a mole ratio of 1:1 so:
moles Ag+ = moles Cl-, therefore Ag+ has 0.01 moles and Cl- has 0.01 moles
- MCl also has a 1:1 ration
moles Cl- = moles M+
- 0.01 moles of M+ and Cl-
0.01 Cl- = x/35.45 = 0.3545g Cl-
mass MCl = 0.74g
0.74g MCl - 0.3545g Cl- = 0.3955g M+
0.3955g M+/x =0.010 mol M+
x= 39.55g M+
K+ has a molar mass of approximately 39.10
Therefore KCl is your answer

Explanation:
The double red program is a program where red blood cells are donated by people . This red blood cells are used for treatment of patients that require red blood cells such as transplant of organs, transplant of tissues, treatment of cancer e.t.c.
Apheresis is a process whereby blood is collected or removed from the body and it undergoes the process of filtration into various components of the blood.
The machine that is used during apheresis collects the human blood and separates it into white blood cells, red blood cells and platelets.
Answer:
evacuate all wildlife from the bay
Explanation:
Algal bloom is a term used to describe the excessive growth of algae species in a water body. This excessive growth or proliferation is as a result of the exposure to nutrient in form of pollutants, a process called Eutrophication.
However, the presence of an algal bloom indicates the pollution of that water body, which will result in the degradation of the pollutants by bacteria. As bacteria acts on the pollutants in the water body, they excessively use the dissolved oxygen of the water body, hence, drastically reducing the oxygen levels of the water. This possess a great threat to aerobic wildlife in the water, which could die as a result of suffocation or anorexia.
Hence, the most important thing to do in a case of noticing an algal bloom in a bay is to evacuate all wildlife from the bay in order to prevent mass death.
Answer:
The leaf discs only float in bicarbonate solution and in the light environment.
Explanation:
The bicarbonate dissolves in water to produce a source of inorganic CO2 in the reaction:
NaHCO3 + H2O → H2CO3 + OH- + Na+
Then, the HCO3- undergoes fixation through several complex steps in order to form a carbohydrate or sugar. These store the converted solar energy in their bonds as chemical energy to be used in metabolism.
Photosynthesis is a chemical process, essential to plant and other primary producers producing energy. Energy in the form of glucose molecules is derived from solar or light energy, water, and inorganic carbon dioxide, while it releases oxygen (from the light reaction). The leaf discs float as O2 gas is produced, making them buoyant.
6CO2 + 6H20 + (energy) → C6H12O6 + 6O2
Carbon dioxide + water + energy= glucose + oxygen
