8 0

Answer:

When two distinct elements are chemically combined for example, chemical bonds form between their atoms, the result is called a chemical compound. Most elements on Earth bond with other elements to form chemical compounds, such as sodium and Chloride, which combine to form table salt.

Which type of lipid is found in the body and is converted into vitamins, hormones, and bile salts?
Illusion [34]

Answer:

C.sterols

Explanation:

Sterols or steroid alcohols are type of lipids. In plants they are present as phytosterols and in animals as zoosterols. They maintain the fluidity of cell membrane, act as signalling molecules and also form the skin oils in animals.

Cholesterol is an important zoosterol. It is a fatty waxy substance. It is present in cell membrane. It is also a precursor for vitamin D. It is precursor for steroid hormones like cortisol and aldosterone. When it is non esterified, it gets converted to bile.

A saline solution contains 0.770 gg of NaClNaCl (molar mass = 58.55 g/molg/mol) in 133 mLmL of solution. Calculate the concentra
lukranit [14]

Answer:

0.104 M

Explanation:

<em>A saline solution contains 0.770 g of NaCl (molar mass = 58.55 g/mol) in 133 mL.</em>

<em />

The molar mass of the solute (NaCl) is 58.55 g/mol. The moles corresponding to 0.770 g are:

0.770 g × (1 mol/55.85 g) = 0.0138 mol

The volume of solution is 133 mL. In liters,

133 mL × (1 L/1000 mL) = 0.133 L

The molarity of NaCl is:

M = moles of solute / liters of solution

M = 0.0138 mol / 0.133 L

M = 0.104 M
