Answer:
Explanation:
When looking at a chemical reaction, the substance present before the reaction takes place are called the (5)
REACTANT
and the substance produced after the reaction are the (6).
PRODUCT
know through the Law of Conservation of (7)
MATTER
that nothing is created or destroyed. This is reflected in a (8
BALANCED
chemical equation, where the NUMBER OF atoms of each element on each side of the arrow is (9)-
equal
or the same.
REMEMBER: WHEN BALANCING EQUATIONS YOU CANNOT CHANGE THE SUBSCRIPTS OF THE COMPOUNDS, YOU CAN ONLY SHOW BY THE COEFFICIENTS HOW MANY MOLECULES YOU HAVE!
Answer: 4.8 grams of hydrogen is 2.4 moles, and 38.4 grams of oxygen is 1.2 moles. This is exactly the Stoichiometry ratio of the reaction, therefore the two will both completely react giving rise to the same total mass of water.
ΔH = -420.16 KJ when 2.6 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,
1/8 mol of S₈ reacts ΔH = -20.2 kJ
1 mol will react ΔH = -20.2 × 8
= -161.6 KJ
2.6 mol will react ΔH = -161.6 × 2.6
= -420.16 KJ
Thus from the above conclusion we can say that ΔH = -420.16 KJ when 2.6 g of S₈ reacts.
