Explanation:
2HCl(aq) + ZnS(s) ⇒ ZnCl₂(aq) + H₂S(g)
<h3>Further explanation </h3>
Equalization of chemical reactions can be done using variables. Steps in equalizing the reaction equation:
- 1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c, etc.
- 2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index (subscript) between reactant and product
- 3. Select the coefficient of the substance with the most complex chemical formula equal to 1
Reaction
HCl(aq) + ZnS(s) ⇒ ZnCl₂(aq) + H₂S(g)
1. give equation
aHCl(aq) + bZnS(s) ⇒ ZnCl₂(aq) + cH₂S(g)
2. make an equation
H, left=a, right=2c⇒a=2c(eq 1)
Cl, left=a, right=2⇒a=2⇒c=1(from eq 1)
Zn, left=b, right=1⇒b=1
So the equation :
2HCl(aq) + ZnS(s) ⇒ ZnCl₂(aq) + H₂S(g)
433.8267 g/mol according to Chemical aid
Activation energy is the energy needed to begin breaking the bonds of reactants and is denoted as option D.
<h3>What is a Reactant?</h3>
These are the substances which take part in a chemical reaction and result in the formation of the product.
The activation energy is required as it breaks the bonds of the reactant thereby resulting in the product being formed. This therefore makes it the most appropriate choice.
