Wewaii [24]

Answer: SrCl_2(aq)+K_2CO_3(aq)\rightarrow 2KCl(aq)+SrCO_3(s)

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.

A double displacement reaction in which one of the product is formed as a solid is called as precipitation reaction.

The balanced chemical equation is:

SrCl_2(aq)+K_2CO_3(aq)\rightarrow 2KCl(aq)+SrCO_3(s)

________ is an indication of how near the air is to saturation rather than the actual quantity of water vapor in the air.
hjlf

Answer: Relative humidity

Explanation:

Relative humidity (RH) is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at a given temperature. Relative humidity depends on temperature and the pressure of the system of interest. The same amount of water vapor has higher relative humidity in cool air than in warm air. A related parameter to that regard is that of dew point.
