Question

balance the chemical equation by selecting the appropriate coefficient for each substance. enter 1 if the coefficient is 1. do not leave it blank. a. sb(s) + cl₂(g) → sbcl₃(s)

Explanation:

Step1: Count atoms

On the left - hand side: 1 Sb atom and 2 Cl atoms. On the right - hand side: 1 Sb atom and 3 Cl atoms.

Step2: Balance Cl atoms

Find the least common multiple of 2 and 3 for Cl atoms. The LCM of 2 and 3 is 6. So, we need 3 \(Cl_2\) (since \(3\times2 = 6\) Cl atoms) and 2 \(SbCl_3\) (since \(2\times3=6\) Cl atoms).

Step3: Balance Sb atoms

After balancing Cl atoms, we have 2 \(SbCl_3\). To balance Sb atoms, we need 2 Sb atoms on the left - hand side.

Answer:

\(2Sb(s)+3Cl_2(g)\to2SbCl_3(s)\)
