Question

consider the following diagram of a hypothetical reaction.
which of the following equations best describes the reaction?
choose 1 answer:
a ( x_{2}+2 y \to x_{2} y_{2} )
b ( x_{2}+2 y \to 2 x y )
( 2 x+2 y \to x_{2} y_{2} )
d ( 2 x+2 y \to 2 x y )

Explanation:

Step1: Analyze reactants

The reactants are one molecule of \(X_2\) (two green spheres) and two atoms of \(Y\) (two red spheres).

Step2: Analyze products

The products are two molecules of \(XY\) (each has one green sphere and one red sphere).

Step3: Write the balanced equation

Based on the number of reactant and product species, the balanced equation is \(X_2 + 2Y
ightarrow 2XY\).

Answer:

B. \(X_2 + 2Y
ightarrow 2XY\)
