Photosyntheis is a biochemical reaction that combines chemicals with biological species to produce energy. Atoms of hydrogen bond with carbon to form glucose.
<h3>What are the reactants and the products of the light reaction?</h3>
Carbon dioxide and hydrogen are the reactants that are used from the environment by the plants to make energy. Glucose and oxygen are the products.
The hydrogen atoms from the environment are absorbed by the plants and are combined with the carbon dioxide to yield glucose or sugar molecules for energy.
Therefore, option B. hydrogen and carbon dioxide react to produce glucose.

Explanation:
First, we will calculate the entropies as follow.
J/K mol
As, 
= 298 K, 
= 373.8 K
Putting the given values into the above formula we get,
J/K mol
= 
= 18.5 J/K mol
Now,
= 
= 94.2 J/mol K
Also,
= 
= 33.4 J/K mol
Now, we will calculate the entropy of one mole of methanol vapor at 800 K as follows.
= (126.8 + 18.5 + 94.2 + 33.4) J/K mol
= 272.9 J/K mol
Thus, we can conclude that the entropy of one mole of methanol vapor at 800 K is 272.9 J/K mol.
ΔH=MCΔT
ΔH=100 x 4.2 x 4
ΔH=1680
ΔH per mole = ΔH ÷ moles
ΔH per mole = 1680 ÷ 0.02
<span>ΔH per mole= 84000Jmol
</span>84000 ÷ 1000 = 84KJmol
its exothermic as heat is given out into the solution
Answer:
Explanation:
[ H⁺] = 3.5 x 10⁻⁶ M .
[ H⁺] [ OH⁻] = 10⁻¹⁴
[ OH⁻] x 3.5 x 10⁻⁶ = 10⁻¹⁴
[ OH⁻] = 2.857 x 10⁻⁹ M .
