Question

1. choose all that apply.

the following chemical equation shows the formation of lead (ii) chloride.
pbo(s) + hcl(aq) → pbcl₂(s) + h₂o(l)
which two statements are correct?
pbcl₂ and h₂o are the reactants.
pbcl₂ and h₂o are the products.
pbo and hcl are the products.
pbo and hcl are the reactants.

Explanation:

In a chemical equation, the substances on the left - hand side of the arrow ($
ightarrow$) are reactants, and the substances on the right - hand side are products. For the equation $\ce{PbO}(s)+\ce{HCl}(aq)
ightarrow\ce{PbCl_{2}}(s)+\ce{H_{2}O}(l)$:

• Reactants are $\ce{PbO}$ and $\ce{HCl}$ (left of arrow).
• Products are $\ce{PbCl_{2}}$ and $\ce{H_{2}O}$ (right of arrow).

So the correct statements are " $\ce{PbCl_{2}}$ and $\ce{H_{2}O}$ are the products" and " $\ce{PbO}$ and $\ce{HCl}$ are the reactants".

Answer:

B. $\ce{PbCl_{2}}$ and $\ce{H_{2}O}$ are the products.
D. $\ce{PbO}$ and $\ce{HCl}$ are the reactants.
