nydimaria [60]

Answer:

                     Cp  =  0.237 J.g⁻¹.°C⁻¹

Explanation:

                      Amount of energy required by known amount of a substance to raise its temperature by one degree is called specific heat capacity.

The equation used for this problem is as follow,

                                                 Q  =  m Cp ΔT   ----- (1)

Where;

           Q  =  Heat  =  640 J

           m  =  mass  =  125 g

           Cp  =  Specific Heat Capacity  =  <u>??</u>

           ΔT  =  Change in Temperature  =  43.6 °C  -  22 °C  =  21.6 °C

Solving eq. 1 for Cp,

                                Cp  =  Q / m ΔT

Putting values,

                                Cp  =  640 J / (125 g × 21.6 °C)

                                Cp  =  0.237 J.g⁻¹.°C⁻¹

What is responsible for the formation of a solution?
-BARSIC- [3]
<span>An aqueous solution is produced when a solute dissolves in water. The biggest responsible is the water that is the solvent of substances in smaller proportion as some ions of K +, Na +, Cl -, forming true solutions. Occurs when a solute dissolves in the water solvent, the separation between the substances is atomic, molecular or ionic, depending on the solution.</span>
