The reaction between HCl and NaHCO3 should take place quickly and release gaseous CO2. You will then use the mass lost of the CO2 to determine the amount of NaHCO3 that reacted.
If 1.60 g of CO2 were lost, how many grams of NaHCO3 would have reacted to produce this amount of CO2?
for the reaction 2 no2 g --gt n2 g 2 o2 g3.60 bar of no2 g is initially placed in a 1.00 l container. at equilibrium

Acetylene gas (ethyne; HC?CH) burns in an oxyacetylene torch to produce carbon dioxide and water vapor, and the heat needed to weld metals. The heat of reaction for the combustion of acetylene is -1259 kJ/mol. (a) Calculate the C?C bond energy, and..
The second law states that the entropy of the universe (system and surroundings) increases in a spontaneous process : delta Ssyst + delta Ssurr is greater than or equal to 0.
at a particular temperature, N2O5 decomposes according to a first-order rate law with a half-life of 3.0s. If the initial concentration of N2O5 is 1.0x10^-6 molecules/cm^3, what will be the concentration in molecules/cm^3 after 26.1s
The heat of solution of ammonium chloride (NH4Cl(s)) in water is +14.7 kJ/mol. Calculate the mass (in g) of NH4Cl(s) required to change the temperature of (1.2550x10^2) ml of water from (2.440x10^1) °C to (5.30x10^0) °C.
