Question

2 Nal + Pb(NO3)2 2 NaNO3 + Pb12 What are the reactants in this equation?

Answer 1

Answer:

$\boxed {\boxed {\sf A. \ NaI \ and \ Pb(NO_3)_2}}$

Explanation:

In a chemical reaction, the reactants are the substances that start the reaction and change into other substances. The results at the end of the reaction are products.

Typically, the reactants are to the left of the arrow, while products are to the right.

• reactants ⇒ products

We are given this chemical equation:

$2 \ NaI + Pb(NO_3)_2 \rightarrow 2NaNO_3 +PbI_2$

We are asked to find the reactants. Remember, these go into the reaction and are on the left.

$\bold {2 \ NaI + Pb(NO_3)_2 } \rightarrow 2NaNO_3 +PbI_2$

Therefore, the reactants are NaI (sodium iodide) and Pb(NO₃)₂ (lead nitrate). Choice A is correct.

Answer 2

I think it may be A but I’m not to certain
