In a 1.000 L sealed container at STP you decompose 100 g sodium Bicarbonate if you ignore the volume of the solid products what is the pressure in the container?

Find the volume of HCl gas at STP required to prepare 3.30 L of a 0.129 m HCl solution (assume water density = 1.00 g/mL). Type your numeric answer and submit

A flask contains 0.023 M H₂ gas at a pressure of 180 mmHg. Nitrogen gas (N₂) is added to bring the total pressure of the flask to 1.00 atm at constant temperature. a. What is the temperature of the H₂ gas in the flask? b. What is the concentration of N₂ gas in the flask? c. What are the mole fractions of the N₂ and H2 gases in t flask? d. The mixture of N2 and H2 gas reacts to produce ammonia, NH3, according to the equation below. How many moles of NH3 can be formed from the H2 and N2 in the flask? N2 (g) + 3H2(g) → 2NH3(g) e. Which of the gases in the container would have the highest average kinetic energy? f. Which of the gases in the container would have the greatest average speed?
