Question

bacl₂ + li₂so₄ → 2licl + baso₄
the reactants are:
blank and
blank
and the products are
blank and
blank
options: licl, li₂so₄, bacl₂, baso₄

Explanation:

Step1: Identify Reactants

In a chemical equation, reactants are on the left of the arrow. Here, reactants are $\ce{BaCl2}$ and $\ce{Li2SO4}$.

Step2: Identify Products

Products are on the right of the arrow. Here, products are $\ce{2LiCl}$ (simplifies to $\ce{LiCl}$ in terms of formula unit for identification) and $\ce{BaSO4}$.

Step3: Match with Options

Reactants: $\ce{BaCl2}$ (option with $\ce{BaCl2}$) and $\ce{Li2SO4}$ (option with $\ce{Li2SO4}$). Products: $\ce{LiCl}$ (option with $\ce{LiCl}$) and $\ce{BaSO4}$ (option with $\ce{BaSO4}$).

Answer:

Reactants: $\ce{BaCl2}$ (the option with $\ce{BaCl2}$) and $\ce{Li2SO4}$ (the option with $\ce{Li2SO4}$); Products: $\ce{LiCl}$ (the option with $\ce{LiCl}$) and $\ce{BaSO4}$ (the option with $\ce{BaSO4}$)

(If we need to list as per the boxes: Reactants are the box with $\ce{BaCl2}$ and the box with $\ce{Li2SO4}$; Products are the box with $\ce{LiCl}$ and the box with $\ce{BaSO4}$)
