Answer:

Mitosis meiosis

Explain:

Mitosis is where the cell splits into 2 more cells (diploid)

Meiosis is where the cell splits into 2, and then split again, making 4 (haploid)

The vapor pressure of pure water at 30°C is 40 torr. If NaCl is dissolved into a sample of water until the total vapor pressure

Dmitry_Shevchenko [17]

Answer:

Mole fraction is 0.2

Explanation:

You have to apply the colligative property about vapour pressure which formula is:

ΔP = P° .Xm

Where ΔP = P° - P

Pressure of vapour from pure solvent (P°) - Pressure of vapour from solution

40 Torr - 32 Torr = 40 Torr . Xm

8 Torr / 40 Torr= 0.2. > Xm

Account for the change when NO2Cl is added using the reaction quotient Qc. Match the words in the left column to the appropriate

ryzh [129]

Answer:

A. Disturbing the equilibrium by adding NO2Cl decreases Qc to a value less than Kc.

B. To reach a new state of equilibrium, Qc therefore increases which means that the denominator of the expression for Qc decreases.

C. To accomplish this, the concentration of reagents decreases, and the concentration of products increases.

Explanation:

Hello,

In this case, for the equilibrium reaction:

$NO_2Cl(g)+NO(g)\rightleftharpoons NOCl(g)+NO_2(g)$

Whose equilibrium expression is:

$Kc=\frac{[NO_2][NOCl]}{[NO_2Cl][NO]}$

The proper matching is:

A. Disturbing the equilibrium by adding NO2Cl decreases Qc to a value less than Kc, since the denominator becomes greater, therefore, Qc decreases.

B. To reach a new state of equilibrium, Qc therefore increases which means that the denominator of the expression for Qc decreases, since the lower the denominator, the higher Qc as it has the concentration of reactants.

C. To accomplish this, the concentration of reagents decreases, and the concentration of products increases, since the reactants must be consumed in order to reestablish equilibrium by shifting the reaction towards the products.

Best regards.
