<span>The answer to your question is letter A. study how cholesterol is broken down in the body. Biology is a study of life which deals with cells, organelles, and other essential parts of the body or organism. Chemistry is a study about chemicals and how it reacts to natural state. In studying about cholesterol in the body, the presence of biologist and chemists will study how the body reacts with the chemicals and substances that were stored in the cholesterol.</span>
2 hydrogens and an Oxygen
From the given chemical equation we see that 43 kcal of
energy is needed for every 2 moles of NO. First let us calculate the moles of
NO with a molar mass of 30 g/mol.
moles NO = 112 g / (30 g/mol) = 3.73 mol
So the total heat absorbed is:
heat = (43 kcal / 2 mol) * 3.73 mol
<span>heat = 80.195 kcal</span>
Answer:
Most soils have pH values between 3.5 and 10. In higher rainfall areas the natural pH of soils typically ranges from 5 to 7, while in drier areas the range is 6.5 to 9. Soils can be classified according to their pH value: 6.5 to 7.5—neutral
