ΔH = -15.78 KJ when 25.0 g of S₈ reacts.
<h3>What is Balanced Chemical Equation ?</h3>
The balanced chemical equation is the equation in which the number of atoms on the reactant side is equal to the number of atoms on the product side in an equation.
The given reaction balanced equation is:
1/8 S₈(s) + H₂(g) → H₂S(g) ΔH = -20.22kj
Now,
When 1 mol will react, then ΔH = -20.2 × 8
= -161.6 KJ
When 1 mol of S8 = 8 × 32 g
= 256 g
When 256g of S8 react ΔH = -161.6 KJ
When 1 g reacts, ΔH = 
=- 0.63125 KJ
When 25 g reacts, ΔH = - 0.63125 × 25
= -15.78 KJ
Thus from the above conclusion we can say that ΔH = -15.78 KJ when 25.0 g of S₈ reacts.

Answer:
7.01 is the answer of the [H+] of a solution with a pH of 4.78
Answer:
I hope it help you the wavelength is 1.9130E-28
Answer:
20 neutrons
Explanation:
neutrons = mass number - atomic number
mass number = 39, atomic number = 19
neutrons = 39 - 19 = 20
Answer:
a). The products are C6H12O6 O2 and the reactants are CO2 + H20 + (solar (light) energy)
b). The reaction chemical reaction is balanced from the number of moles of reactants and products
Explanation:
Through photosynthesis green plants, some protistans and some bacteria in the presence of energy from sunlight, produce glucose as well as oxygen from carbon dioxide and water.
It is a chemical reaction taking place in green plant to produce food which it uses to survive.
Photosynthesis requires carbon dioxide, water and solar energy in the leaves of a plant for it to take place.
The equation for photosynthesis is as follows: 6CO2 + 6H20 + (solar (light) energy) → C6H12O6 + 6O2
The products are C6H12O6 O2
and the reactants are CO2 + H20 + (solar (light) energy)
The reaction chemical reaction is balanced from the number of moles of reactants and products
