DNA stores a cell’s genetic information. During interphase, unwound chromosomes containing DNA replicate, forming an X-shape. Th

is is still considered one chromosome, but now it has twice as much genetic material.
How does this help explain why daughter cells are identical after mitosis?

Daughter cells are identical after mitosis because they have a copy of the chromosome. Not sure if this helped though

Because during mitosis one mother cell is divided to two daughter cells so we need to replicate the genetic material so we have the same number of chromosomes in both cells. so yeah that’s why they are identical/have the same genetic material. hope this helped

Carbon tetrachloride reacts at high temperatures with oxygen to produce two toxic gases, phosgene and chlorine.CCl4(g) + (1/2)O2
Elodia [21]

Answer : The value of K'_c for the reaction is, 1.9\times 10^{19}

Explanation :

The given equilibrium reactions are:

(1) CCl_4(g)+\frac{1}{2}O_2(g)\rightleftharpoons COCl_2(g)+Cl_2(g)       K_c=4.4\times 10^9

(2) 2CCl_4(g)+O_2(g)\rightleftharpoons 2COCl_2(g)+2Cl_2(g)      K'_c=?

As we know that,  when we are multiplying the equation (1) by 2 then we get the equation (2). Thus, the relation between the two equilibrium constant will be,

K'_c=(K_c)^2

So,

K'_c=(4.4\times 10^9)^2

K'_c=1.9\times 10^{19}

Therefore, the value of K'_c for the reaction is, 1.9\times 10^{19}

Compound 1 has a composition of 46.7 mass % of element A and 53.3 mass % of element B. A and B also form a second binary compoun
Leviafan [203]

A summary of the Law of multiple proportions is that if A and B form more than one compound, and B1 is the amount of element B which reacts with a fixed mass of A in compound 1, and B2 is the amount of B which reacts with the same fixed mass of B to form compound 2, then the ratio B1:B2 will be small whole numbers.

This law is rather simplistic, and given the range of compounds known today the definition of 'small' is now rather large... but, to answer the question:

in compound one 1.14133g of B reacts with 1g of A. (1.14133=53.3/46.7)

g What is the half-life for a particular reaction if the rate law is rate = (1291 M⁻¹*min⁻¹)[A]² and the initial concentration o
Gnoma [55]

Answer:

t_{1/2}=3.10x10^{-3}min=0.186s

Explanation:

Hello,

In this case, for the calculation of the half-life for the mentioned reaction we first must realize that considering the units of the rate constant and the form of the rate law, it is a second-order reaction, therefore, the half-life expression is:

t_{1/2}=\frac{1}{k[A]_0}

Therefore, we obtain:

t_{1/2}=\frac{1}{1291\frac{1}{M*min}*0.250M}\\\\t_{1/2}=3.10x10^{-3}min=0.186s

Regards.
