A 12.0 mL sample of a compound has a density of 1.44 g/mL. What is the weight of the sample in g?
a sample of oxygen at 48 c occupies 622 ml.if this sample later occupies 1252 ml at 55 c and 1.4 atm what was its
How do you find the theoretical mol of HC2H3O2 if you have 33.0 g of acetaldehyde and 16.5 g of oxygen and only produced 18.02 g of acetic acid 2CH3CHO + O2--> 2HC2H3O2
0.300 moles of an unknown monobasic weak acid are added to 1.20 l of water. the resulting solution has a ph of 8.800.
At 25 °C, the equilibrium partial pressures for the following reaction were found to be PA = 1.40 atm, PB = 8.90 atm, PC = 5.10 atm, and PD = 2.50 atm.
Calculate the maximum amount of CO2 that can be produced when 64.0 g of O2 and 64.0 g of CH3 OH are mixed for the reaction 2 CH3OH + 3 O2 → 2 CO2 + 4 H2 O .
Sort the subsequent reactants into one of these three categories- arrhenius/bronsted- lowry acid, arrhenius base, bronsted- lowry base, based upon their actions in the reactions shown
