If the partial pressure of a gas over a solution is doubled, how has the concentration of gas in the solution changed after equilibrium is restored? If the partial pressure of a gas over a solution is doubled, how has the concentration of gas in the solution changed after equilibrium is restored? The concentration of gas in the solution would half. The concentration of gas in the solution would double. The concentration of gas in the solution would triple. The concentration of gas in the solution would not change.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.

pv=nrt

explanation:

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
