WebOct 19, 2024 · First, we will write the balanced equation of reaction properly CH₄ (g) +4Cl₂ (g) → CCl₄ (g) + 4HCl (g) This means that, 1 mole of CH₄ would react with 4 moles of Cl₂ to yield 1 mole of CCl₄ and 4 moles of HCl Now, we will determine the number of moles of methane and that of chlorine gas present. From the question, mass of methane = 19.2 g Webd = 4 (HCl) Substitute Coefficients and Verify Result Count the number of atoms of each element on each side of the equation and verify that all elements and electrons (if there are charges/ions) are balanced. SiCl4 + 4 H2O = H4SiO4 + 4 HCl
