CaBr2
Because of the criss cross method of switching the charges
The product of the reaction as it has been shown above is butoxymethane.
<h3>What is a chemical reaction?</h3>
A chemical reaction is an interaction that takes place between two or more chemical substances to yield a product (s). We should note that the reactants are written at the left hand side of the reaction equation while the products are written at the right hand side of the reaction equation. This is how we show reaction on paper.
Having said this, the reaction that have been shown in the question would occur by an SN2 synchronous mechanism to yield butoxy methane product.

Gibb's free energy, ΔG°, is related to the equilibrium constant of the reaction, K, through the equation:
ΔG°= RT(ln K)
By definition, K is the ratio of the equilibrium partial pressure of the products to the reactants, raised to the power of their stoichiometric coefficients, respectively. For this reaction,
N₂ (g) + 3 H₂ (g) → 2 NH₃<span> (g)
the equilibrium constant is
K = [NH</span>₃]²/[N₂][H₂]³
Assuming that the given partial pressures are the equilibrium pressures, then we can substitute them directly:
K = [0.65 atm]²/[1.9 atm][1.6 atm]³
K = 0.05429 atm⁻²
Then, we can using this value to find ΔG. Note that R is the gas constant equal to 0.08206 L-atm/mol-K.
ΔG°= (0.08206 L-atm/mol-K)(298 K)(ln 0.05429 atm⁻²)
ΔG° = -71.244 L-atm/mol
Work done=50J
Heat removed=29J
Now
Hence the internal energy would increase by 21J
Option B s correct
