Answer : The correct option is, (C) lead
Explanation :
Balanced chemical reaction : It is defined as the reaction in which the atoms of individual elements present on the reactant side must be equal to the product side.
As per question, when lead react with bromine then it gives lead bromide as a product.
The balanced chemical reaction will be,
![\text{Lead}+\text{Bromine}\rightarrow \text{Lead bromide}](https://img.qammunity.org/2020/formulas/physics/high-school/6p0mbxlcfovx5n74qdt5jxbi35nnnw1mpx.png)
Or,
![Pb(s)+Br_2(g)\rightarrow PbBr_2(l)](https://img.qammunity.org/2020/formulas/physics/high-school/2xxbd7tt81gp6aijhj37n42zjn7vshe1ow.png)
Hence, the element missing from the following reaction is, lead.
