Calculate the number of CO2 molecules (NCO2)in 0.0639 mol of CO2. Express your answer using three significant figures.

Suppose a 250. mL flask is filled with 0.20 mol of H₂S, 1.1 mol of CS2 and 1.2 mol of H₂. This reaction becomes possible: CH₂(g) + 2H₂S (g) = CS₂(g) + 4H₂(g) Complete the table below, so that it lists the initial molarity of each compound, the change in molarity of each compound due to the reaction, and the equilibrium molarity of each compound after the reaction has come to equilibrium. Use x to stand for the unknown change in the molarity of CH4. You can leave out the M symbol for molarity. initial change equilibrium CH4 X H₂S 0 CS2 0 H₂ 0 X S

2 NH3 + 3 CuO → 3 Cu + N₂ + 3 H₂O In the above equation, how many grams of N₂ can be made when 10.9 moles of CuO are consumed? Round your answer to the nearest tenth. If you answer is a whole number like 4, report the answer as 4.0 Use the following molar masses. If you do not use these masses, the computer will mark your answer incorrect.: Element Molar Mass Hydrogen 1 Nitrogen 14 Copper 63.5 Oxygen 16
