Consider the following balanced reaction. How many moles of O2 are need to produce 0.956 moles of SO2? Assume excess C3H¬SH.

What mass of H2O is produced when 0. 400 mol of KOH react completely in the following equation? KOH + HCl → KCl + H2O a. 90.2 g b. 18.0 g c. 45.1 g d. 7.21 g

I have attached an image. Thank you.

Balance the following equation. What is the sum of the coefficients in the balanced equation? KCIO;(s) + P(s) - P,O10(s)+ KCI(s)

(4) for the reaction : 2 NaHCO3 → Na₂CO₂ + H₂O + CO₂ Find the mass of Sodium Carbmate that reacted from 1.56g of heated Sodium Hydrogen Carbonate

Balance, and when needed, completethe following chemical reactions, and attribute each to a corresponding reaction type (decomposition, double replacement, single replacement, combination (synthesis), combustion): SO2 + O2 --> SO3
