The term hydrate would mean that the compound contains water molecules. When this compound is heated, the water molecules are lost first which means that what remains would be the dried compound. Therefore, the H2O lost from the hydrate would be 6.00g - 3.27g = 2.73 g.

Answer:

The human body when metabolizing meat, milk or eggs, being high in protein, manufactures uric acid as a metabolite, and releases more urea in the urine.

Uric acid generates an increased retention of liquid or water, that is why people who ingest excessively meat suffer from GOTA disease.

Gout disease is systemic and life-threatening puffiness.

Furthermore uric acid is an organic compound of carbon, nitrogen, oxygen and hydrogen. Its chemical formula is C5H4N4O3. It is found in urine in small amounts.

And urea is defined as a renal parameter from the quantitative point of view; It is a colorless, crystalline chemical compound of formula CO (NH2) 2. It is found abundantly in urine and faeces.

Explanation:

To have an accurate idea of the function of the kidneys, it is sufficient to carry out a simple blood test with determination of Urea and creatinine and an analysis of a urine sample in which the presence of cells (red blood cells and leukocytes) is assessed. and / or proteins (albumin). Today these 2 types of analysis are part of the routine of any analytical study.

ahrayia [7]

Answer:

2.67g of NH4Cl are required

Explanation:

Molarity is an unit of concentration in chemistry defined as the moles of solute (In this case, NH4Cl), per liter of solution.

To prepare 100mL of a 0.50M are required:

100mL = 0.100L * (0.50 moles / L) = 0.0500 moles NH4Cl

As molar mass of NH4Cl is 53.491g/mol:

0.0500 moles * (53.491g / mol) =

<h3>2.67g of NH4Cl are required</h3>
