How many ml of 12.0 M H2S04 are needed to make 500.0 ml of a 1.00 M solution? What happens to the freezing point and the boiling
lora16 [44]

Answer:

41.66 mL of 12.0 M sulfuric acid are needed.

Explanation:

Concentration of sulfuric acid solution taken =M_1=12.0M

Volume of the 12.0 M Solution = V_1

Concentration of required solution = M_2=1.00M

Volume of required 1.00 M solution = V_2=500.0 mL

M_1V_1=M_2V_2 (Dilution)

V_1=\frac{1.00 M\times 500.0 mL}{12.0 M}=41.66 mL

41.66 mL of 12.0 M sulfuric acid are needed.

The freezing point and the boiling point of a solvent when a non-volatile solute is dissolved in it decrease and increase respectively.

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.

At equilibrium, no chemical reactions take place. true or false
arsen [322]
False. At equilibrium, the rate of forward reaction is equal to the rate of backward reaction. The net concentration of both products and reactants won't change, but the reactions still take place.
