Is there enough info to calculate the pressure of gas if the barometric pressure is 755 torr and if so what is the answer. If not, how would you derive the answer if you had all of the parts to the problem?
Calculate the partial pressures of the gases if the total pressure is 2.00atm at a given temperature.
When doing the kinetic trial, Peyton mistakenly omitted the starch solution from the kinetic trials. How will this omission change the appearance of the resultant solution (from mixing solutions A&B) from that of a correctly completed expiernment?..
Three gases (8.00 rm g of methane, CH_4, 18.0 g of ethane, C_2H_6, and an unknown amount of propane, C_3H_8) were added to the same 10.0 L container.
A sample of gas with a mass of 1.58 occupies a volume of 941 at a pressure of 753 and a temperature of 16. What is the molar mass of the gas.
a student measured 50.0 ml of a salt water solution (density=1.021 g/ml) into a flask. The Cl minus in the measured sample required 16.67 ml of 1.0466 M AgNO3 solution to reach the end point.
the addition of bromine to an equimolar mixture of cis- and trans-2-butene generates only three stereoisomers. Explain.
