Agas container is initially at 47 mm hg and 77 k (liquid nitrogen temperature.) what will the pressure be when the container warms up to room temperature of 25 c?

181.90 mmHg

In this case, we are given;

Initial temperature, T1 = 77 K

Initial pressure, P1 = 47 mmHg

Final temperature, T2 = 25 °C + 273

                                     = 298 K

We are required to find the final pressure;

Using pressure law;

P2 = (P1/T1)T2

    = (47/77K) × 298 K

    = 181.90 mmHg

Therefore, the new pressure will be 181.90 mmHg

answer; ///(d) the correct answer is double or triple

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.
