Calcium reacts with water. This reaction is represented by the balanced equation below. The aqueous product of this reaction can be heated to evaporate the water, leaving a white solid, Ca(OH)2(s).

Ca(s) + H2O(l) ==> Ca(OH)2(aq) + H2(g)

Compare the electrical conductivity of the aqueous product in the reaction to the electrical conductivity of the white solid that remains after the water is evaporated from the solution.

Write the chemical name of the base produced in the reaction.

State one change in reaction conditions that will increase the rate of the reaction.

Sagot :

The aqueous product conducts electricity while the solid does not. Ionic solids do not conduct electricity, but ions dissolved in solution do. The chemical name of the base is calcium hydroxide. Increasing the temperature of the system would increase the rate of the reaction.

Answer:

- Calcium is more conductive than calcium hydroxide.

- Calcium hydroxide.

- Addition of more either calcium or water to the reaction vessel

Explanation:

Hello,

In this case, based on the given reaction and information, calcium's electrical conductivity 0.298 106/(cm*Ω) which is a relatively high value compared to it its base has due to its large insolubility.

In addition, the name of the formed base is calcium hydroxide based on the IUPAC rules.

Moreover, the addition of more either calcium or water to the reaction vessel will generate more calcium hydroxide.
