Answer: Photosynthesis and cellular respiration are related because the reactants for photosynthesis is the products (plus ATP) is cellular respiration. Also the products for cellular respiration is the reactants for cellular respiration.
Explanation:
Alright yo, I just gave this explanation off earlier
Alright dude, Hess' law isn't as complicated as most people think
Take this example
look for the change in enthalpy of A+B-> AB
A + B -> C enthalpy=10 kJ
C -> AB enthalpy=10 kJ
now if you add everything together you come up with
A + B + C --> AB + C enthalpy= 10kJ + 10 kJ= 20kJ
But notice how C is one the left and on the right of that-- so if it's on the left and on the right of the equation, you could just cancel it out
so you get A+B--> AB
tadaaa!! You found the equation you were looking for
and you know that it's enthalpy is= 10kJ + 10kJ= 20kJ
Hope that helps ya fam!
Just pm me if you need more help!
A spontaneous reaction favours the product formation and increases the entropy of the isolated system. The sign of the entropy change will be negative as the product formation is less random.
<h3>What is entropy?</h3>
Entropy is the degree of the disorder or randomness that occurs in the system that lacks available energy and cannot convert the mechanical energy or work.
The entropy of the reaction will be negative as the reactants are present in the gaseous state and the product formed is solid. The product formation was spontaneous and less random.
Therefore, option a. entropy will be negative as product formation is less random.

C. soil. If this isn’t C it’s definitely B.
Answer:
Q = 143,921 J = 143.9 kJ.
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to calculate the absorbed heat by considering this is a process involving sensible heat associated to the vaporization of water, which is isothermic and isobaric; and thus, the heat of vaporization of water, with a value of about 2259.36 J/g, is used as shown below:
Thus, we plug in the mass and the aforementioned heat of vaporization of water to obtain the following:
