Answer:

Explanation:

Determine the treatments you’ll be using on your eggs, and prepare the substances you’ll need. You can make salt-water solutions by dissolving different amounts of table salt in containers of water (e.g. 100g, 200g, 300g of salt (NaCl) per liter). You can make solutions of food coloring by adding a few drops of each color into containers of  

The Eggsperiment with Vinegar solution. The first experiment conducted was the egg placed in vinegar solution which allowed the egg to become soft and bouncy . Vinegar is a weak acid which is 5% acetic acid in water (meaning vinegar is largely just water). The egg has a shell that is made up of calcium carbonate   an air cell forms at the large end of the egg. While the embryo is growing, the shell membranes surround and contain the white or albumen of the egg. The albumen provides the liquid medium in which the embryo develops, and it also contains a large amount of the protein necessary for proper development. I hope this was hopeful

It is necessary to make 225 mL of 0.222 M solution of nitric acid. Looking on the shelf, you see only 16 M nitric acid. How much
nalin [4]

Explanation:

The required concentration of HNO_3 M1 =0.222 M.

The required volume of HNO_3 is V1 =225 mL.

The standard solution of HNO_3 is M2 =16 M.

The volume of standard solution required can be calculated as shown below:

Since the number of moles of solute does not change on dilution.

The number of moles n=molarity *  volume

M_1.V_1=M_2.V_2

V2=\frac{M_1.V_1}{M_2} \\=0.222M x 225 mL / 16 M\\=3.12 mL

Hence, 3.12 mL of 16 m nitric acid is required to prepare 0.222 M and 225 mL of nitric acid.

The ___ fluid compartment consists of fluid contained within all cells in the body and contains 2/3 of the body water in healthy
photoshop1234 [79]

Answer:

intracellular; extracellular

Explanation:

Intracellular fluid compartment is system which includes all the fluid which is enclosed in the cells by the plasma membranes of these cells. It lies in the cells and acts as the principal component of cytoplasm. ICF makes up about 2/3 of total water in human body.

Extracellular fluid is system which surrounds all the cells in body. The fluid has two primary constituents which are - fluid component of blood (known as plasma) and interstitial fluid (IF) which surrounds all the cells except blood. It accounts for other 1/3 of water content of the body.
