Consider the following gas phase reaction: CH4(g) + 2O2(g)CO2(g) + 2H2O(g)

If 3.98 liters of CH4(g) gas at 121°C and 0.591 atm is used, what volume of O2(g) gas at the same temperature and pressure will be consumed? L?

What volume of H2O(g) gas at the same temperature and pressure will be produced? L?

Which of the following signs of a chemical reaction are observed in the reaction of potassium with water? precipitate formed temperature change smell produced gas produced color change

Match the mixture with the substance// i really need on this guys (it’s a pic btw)

For each of the following compounds, write the formula then predict whether it would be a strong, weak, or non-electrolyte when placed in di water. for the ionic compounds only, put (s) or (aq) after the forrmula formula strong, weak or non electrolyte? a calcium hydroxide b. silver carbonate c. lead(ii) sulfate d. phosphorus trifluoride e. sodium phosphide f barium sulfate g. strontium acetate h. zinc nitrate
