Answer:
1.75 atm
Explanation:
When the pressure that a gas exerts on a sealed container changes from 1.75 atm to 2.64 atm, the temperature changes from 315 K to 475 K.
(2.64 atm) x (315 K / 475 K) = 1.75 atm
The pressure and temperature of a gas in a sealed container are directly proportional. An increase in temperature would imply that the pressure also increased.
Water is known as H2O and soil is known as HYG
Answer: B. endergonic, not spontaneous
Explanation:
Endergonic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and
for the reaction comes out to be positive.
The Gibbs equation is:

= Gibb's free energy change
= enthalpy change
T = temperature
= entropy change
A reaction is non spontaneous when
= Gibb's free energy change is positive



Thus the reaction has to be endergonic.
