Answer:

1) CO₂

2) 0.2551 g

Explanation:

The balanced reactions are:

CaCO₃ + 2HCl → CaCl₂ + H₂O + CO₂

MgCO₃ + 2HCl → MgCl₂ + H₂O + CO₂

1) The gas produced is CO₂.

2) Calculate mass of CaCO₃:

(0.5236 g) (0.4230) = 0.2215 g CaCO₃

Convert to moles:

(0.2215 g CaCO₃) (1 mol / 100.1 g) = 0.002213 mol CaCO₃

Find moles of CaCO₃:

(0.002213 mol CaCO₃) (1 mol CO₂ / mol CaCO₃) = 0.002213 mol CO₂

Convert to mass:

(0.002213 mol CO₂) (44.01 g / mol) = 0.09738 g CO₂

Calculate mass of MgCO₃:

(0.5236 g) (0.5770) = 0.3021 g MgCO₃

Convert to moles:

(0.3021 g MgCO₃) (1 mol / 84.31 g) = 0.003583 mol MgCO₃

Find moles of MgCO₃:

(0.003583 mol MgCO₃) (1 mol CO₂ / mol MgCO₃) = 0.003583 mol CO₂

Convert to mass:

(0.003583 mol CO₂) (44.01 g / mol) = 0.1577 g CO₂

Total mass of CO₂:

0.09738 g CO₂ + 0.1577 g CO₂ = 0.2551 g CO₂

An analysis of chromosomes in a culture containing mutated cells may show the loss of one or more bases making up the chromosome
ankoles [38]

The answer is; deletion mutation


This type of mutation mostly causes a phenomenon called frameshift mutation whereby the 3-codon sequence reading frame is shifted causing the amino acids translated, downstream of the deletion site, to be altered. This can gravely affect the function of the translated proteins and result in genetic disease.

The binding of a compound to an enzyme is observed to slow down or stop the rate of the reaction catalyzed by the enzyme. Increa
Setler79 [48]

Answer:

The correct answer is A the compound is a competitive inhibitor

Explanation:

Competitive inhibitor competes with the substrate to bind to the active site of the target enzyme and after binding to the active site the inhibitor slow down or stop the reaction catalyzed by that enzyme.

          Competitive inhibitor basically effects the Km value of the enzyme thus decreasing the activity of the later.

           Increasing the substrate concentration displace the inhibitor from the enzyme"s active site thus reducing the inhibitory effects of the later thus increasing the activity of the enzyme.
