6 0

Answer:

The enthalpy of the reaction of the reaction asked in the question is 265.2 kJ.

Explanation:

Hg + Cl_2\rightarrow HgCl_2,\Delta H_1 = -224kJ...(1)

Hg + HgCl_2\rightarrow Hg_2Cl_2,\Delta H_2 = -41.2kJ..(2)

Hg_2Cl_2\rightarrow 2Hg + Cl_2,\Delta H_3=?...(3)

(1)+(2)

\Delta H_4=-224kJ+(-41.2kJ)= -265.2 kJ

2Hg+Cl_2\rightarrow Hg_2Cl_2,\Delta H_4=-265.2 kJ...(4)

On reversing the equation (4)we get (3):

\Delta H_4=-265.2 kJ =-(\Delta H_3)

Hg_2Cl_2\rightarrow 2Hg+Cl_2,\Delta H_3=265.2 kJ

The enthalpy of the reaction of the reaction asked in the question is 265.2 kJ.

Explain what is cellular growth and repair? Why is it important?
HACTEHA [7]

Answer:

Cell growth usually refers to cell proliferation, the increase in cell numbers that occurs through repeated cell division. Cell growth can also refer to the enlargement of cell volume, which can take place in the absence of cell division. As living things grow, some cells die or become damaged and need replacements. Some single-celled organisms use a type of mitosis as their only form of reproduction. In multicellular organisms, cell division allows individuals to grow and change by expanding the number of total cells.

Hope this helps!!!

Which describes the products created from fission reactions? Question 3 options:
Ipatiy [6.2K]

<u>Answer:</u> The correct answer is option A.

<u>Explanation:</u>

Nuclear fission reactions are a type of nuclear reactions in which larger nuclei breaks apart into two or more smaller fragment releasing alpha, gamma of beta particles.

There are 3 types of particles that can be released during this process:

1. Alpha particles: These particles are released when a nuclei undergoes alpha-decay process.

_Z^A\textrm{X}\rightarrow _{Z-2}^{A-4}\textrm{Y}+_2^4\alpha

2. Beta particles: These particles are released when a nuclei undergoes beta-minus decay process.

_Z^A\textrm{X}\rightarrow _{Z+1}^{A}\textrm{Y}+_{-1}^0\beta

3. Gamma radiations: these radiations are released when an unstable nuclei gives off excess energy by a process of spontaneous electromagnetic process.

_Z^A\textrm{X}^*\rightarrow _Z^A\textrm{X}+_0^0\gamma

Hence, any of these particles can be released during the process of fission reaction with smaller atoms.

Therefore, the correct answer is option A.
