Question

The reaction of sulfur dichloride (SCl2) and sodium fluoride (NaF) may be represented by the following chemical equation.3SCl 2 ​ +4NaF→S 2 ​ Cl 2 ​ +SF 4 ​ +4NaCl Determine the stoichiometric ratio of NaF to SCl2 in this equation. (Enter the stoichiometric ratio from the balanced equation.)

A) 3 : 4
B) 4 : 3
C) 1 : 1
D) 4 : 1

Answer 1

The stoichiometric ratio of NaF to SCl2 in the given chemical equation is 4:3, representing the amounts in moles of each reactant that reacts with the other.

Step-by-step explanation:

The reaction between sulfur dichloride (SCl2) and sodium fluoride (NaF) is represented by the chemical equation: 3SCl2 + 4NaF → S2Cl2 + SF4 + 4NaCl. To determine the stoichiometric ratio, we look at the coefficients of NaF and SCl2 in the balanced equation. The coefficient in front of NaF is 4, and the coefficient in front of SCl2 is 3. Therefore, the stoichiometric ratio of NaF to SCl2 is 4:3, which corresponds to option B.
