Calculate the number of molecules found in 35 g of Sodium Hydroxide?
Helen [10]

Answer:

5.27*10^23 (rounded to 3 significant figures)

Explanation:

The amount of molecules in one mole of anything is equal to Avogadro's number: 6.022×10^23

To find the number of moles of NaOH in 35 grams of it, do 35 divided by the molar mass (39.997): 35/39.997=0.87506562 moles of NaOH

To find the number of molecules, multiply the moles of NaOH by Avogadro's number: 0.87506562×(6.022×10^23)=5.26964522*10^23

the bond formed between the carboxylic acid group of one amino acid and the amino group of the next amino acid is a(n) bond.
Naya [18.7K]

Peptide bonds are amide connections between two amino acids' -carboxyl and -amino groups.

The covalent link created by the dehydration reaction (loss of a water molecule) between the carboxyl group of one amino acid and the amino group on the next is known as a peptide bond. Peptide bonds are created in polypeptides through a condensation reaction between the carboxyl groups of one amino acid and the amino groups of the following amino acid, all while removing water. When the carboxyl group of one molecule combines with the amino group of the other molecule, releasing a molecule of H2O as a result, a peptide bond is created between the two molecules.

3- Um tipo de nutriente complexo presente
umka21 [38]

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.

How does the understanding of the structure of the atom help you see both unity and diversity in forms of matter?
gtnhenbr [62]
<span>How does understanding the structure of the atom help you see both unity and diversity in forms of matter?</span><span>


Understanding the structure of the atom helps to understand unity in matter because all matter is made up of those very similar atoms. Understanding the structure of the atom helps to understand diversity in matter because matter can be different (solid, liquid, gas, hard, soft, etc) and knowing the structure of the atom can explain these differences.

Hope This Helps! :3</span>
