Answer:
The new pressure is 1,52 atm
Explanation:
We use the gas formula, which results from the combination of the Boyle, Charles and Gay-Lussac laws. According to which at a constant mass, temperature, pressure and volume vary, keeping constant PV / T. We convert the unit Celsius into Kelvin:
75°C=273+75=348K ; 103°C=273+103=376K
(P1xV1)/T1=(P2xV2)/T2
(1,65atm x4,54L)/348K= (P2x 5,33L)/376K
0,0215 atmxL/K=(P2x 5,33L)/376K
P2=(0,0215 atmxL/K x 376K)/5,33l= 1,52 atm
I would go with the cell membrane In this case as the cell membrane is like skin

<u>Answer:</u> of the reaction will be negative, of the reaction will be positive and of the reaction will be negative.
<u>Explanation:</u>
Thermodynamic properties are enthalpy change , entropy change and Gibbs free energy
Exothermic reactions are defined as the reactions in which energy is released in the form of heat. The enthalpy change of the reaction comes out to be negative for this kind of reaction.
Entropy change is defined as the change in the measure of randomness in the reaction. It is represented as . Randomness of gaseous particles is more than that of liquid which is further more than that of solids.
For the given exothermic reaction:
As, number of gaseous particles on the product side is more than the number of gaseous particles on the reactant side. So, the entropy change is positive. Hence, is positive.
The above reaction is spontaneous. Thus, the Gibbs free energy will be negative.
For the given reaction:
