Ammonium carbanate decomposes as follows: NH4CO2NH2 (s) --> 2 NH3 (g) + CO2(g).
Starting with only the solid, it is found that at 40 degrees Celsius the total gas pressure is .563 atm. Calculate the partial pressure of NH3 and CO2.
If 18.2 mL of 0.800 M HCl solution are needed to neutralize 5.00 mL of a household ammonia solution, what is the molar concentration of the ammonia.
An aerosol spray can of deodorant with a volume of 320 mL contains 2.8 g of propane gas (C3H8) as propellant. What is the pressure in the can at 20 degrees Celsius?
The results below are from a titration lab utilizing 25mL of .1M acetic acid which was titrated with the NaOH solution of volume and molarity shown below. Please show how to get the correct pH at equivalence to compare with indicator change
Consider the following equibrium: CO(g) + 3H2(g) = CH4(g) + H2(g) Initially, 0.200 mol CO and 0.600 mol H2 are placed in a 2.00 L container.
