What is the molarity of ZnCl2 that forms when 25.0 g of zinc completely reacts with CuCl2 according to the following reaction? A
yaroslaw [1]

The ZnCl₂ solution have a molarity of 1.33 M.

Explanation:

We have the following chemical reaction:

Zn (s) + CuCl₂ (aq) → ZnCl₂ (aq) + Cu (s)

number of moles = mass / molar weight

number of moles of Zn = 25 / 65.4 = 0.38 moles

From the chemical equation we see that 1 moles of Zn produces 1 mole of ZnCl₂, so 0.38 moles of Zn will produce 0.38 moles of ZnCl₂.

molarity = number of moles / volume (L)

molarity of the ZnCl₂ solution = 0.38 / 0.285 = 1.33 M

A copper coin with a mass of 6.30 grams changes temperature in the sunshine from 20.0°C to 32.0°C. How much energy is transferre
Mariana [72]

The energy transferred is  28.5  j


<em><u>calculation</u></em>

energy is calculate  MCΔT  formula  where,

M(mass)= 6.30  grams

C(specific heat capacity)= 0.377 j/g

ΔT(change in temperature)= 32.0c- 20 c= 12 c


Energy is therefore= 6.30 g   x 0.377  j/g /c x   12 c =<u>28.5 j</u>

What is the development of lymphocytes compared to other formed elements?
Katyanochek1 [597]
Lymphocytes and the other formed elements are developed from pluripotent stem cells. The pluripotent stem cells generate myeloid stem cells and lymphoid stem cells. Myeloid cells start and complete their development in red bone marrow and give rise to red blood cells, platelets, eosinophils, basophils, neutrophils, and monocytes. Lymphoid stem cells begin development in the red bone marrow, but some are completed in the lymphatic tissues, where they give rise to lymphocytes. The B cell lymphocytes begin and finish in the red bone marrow and the T cell lymphocytes begin in the red bone marrow, but they mature in the thymus.
