When potassium chloride reacts with oxygen under the right conditions, potassium chlorate is formed:

2 KCI+ 3O2-->KCIO3

Carbon tetrachloride can be formed by reacting chlorine with methane, calculate the enthalpy of reaction.

CH4+2Cl2-->CCl4+2H2

Calculate the heat of reaction: 2 NO(g)+O2(g)-->2NO2(g)

Calculate the AH for the reaction: CS2(/) + 2 O2(g)-->CO2(g) +2 SO2 (g)

97.30g of a mystery compound is added to 500g of water, raising its boiling point to 100.78°C. What is the molar mass of the mystery compound? kb of water = 0.51°C/m

the concentration of a reactant in a reaction decreases from 0.6 mole/L to 0.2 mole/L. in 10 seconds. Calculate the reaction rate.

CONVERTING MOLE TO MASS

Calculate the number of grams of SO2 that could be produced from 3.25 moles of oxygen (moles 02 →

moles SO2 → g SO2). AW of O = 16 9. S = 32.065 g

4FeS + 702 → 2Fe2O3 + 4SO2 (balanced equation)
