a. nitric acid and potassium carbonate. b. sodium bromide and lead nitrate. c. acetic acid and calcium hydroxide. d. calcium nitrate and sodium sulfate. e. ammonium chloride and lithium hydroxide.
Using appropriate equations, explain why combustion of fuels containing sulfur leads to acid rain.
A 250 mL stock solution contains 2.3 M Ca(CN)2. When 100 mL of the stock solution is diluted to 125 mL, how many moles of CN- ions will be contained in the dilute solution.
Suppose that 347 mL of argon is collected over water at 25 ?C and 715 torr. Compute the volume of the dry argon at STP. The water partial pressure at 25 ?C is 23.8 torr.Answer in units of mL
If a bottle of nail polish remover contains 172 of acetone,how much heat would be released by its complete combustion? The density of acetone is 0.788 .
An object made of aluminum has a mass of 8.37g. When it was placed in a graduated cylinder containing 20.0mL of water, the water level rose to 23.1mL. Calculate the density and specific gravity of the object.
Evaporation and its Effects on PCP and Cresol, We are asked to explain the phenomena of how 1 gram of liquid water at 35 degrees C
A piece of sodium metal reacts completely with water as follows. 2 Na(s) + 2 H2O(l) ->2 NaOH(aq) + H2(g) The hydrogen gas generated is collected over water at 25.0°C. The volume of the gas is 295 mL measured at 1.00 atm.
A refrigeration tank holding 5.00 L of Freon gas (C2Cl2F4) at 25°C and 3.00 atm pressure developed a leak. When the leak was discovered and repaired, the tank had lost 76.0 g of the gas.
Radioactive isotopes often occur together in mixtures. Suppose a 190 sample contains , with a half-life of 12 days, and , with a half-life of 4.5 days. If there are initially twice as many calcium atoms as there are barium atoms, what will be the ..
The sulfur and hydrogen in the fuel are completed oxidized to SO2 and H2O. 8% of the carbon is oxidized to CO, and the balance forms CO2. Calculate the dry basis mole fractions of the flue gas
Find the equation for the work of a reversible, isothermal compression of 1 mol of gas in a piston/ cylinder assembly if the molar volume of the gas is given
Explain why the C=C stretching mode gives rise to a rather weak IR band in 1-methylcyclohexane
