How many moles of gas are in a balloon with a volume of 2.14 liters at a temperature of 298 K and a pressure of 1.11 atm?
A system expands in volume from 2.0 L to 24.5 L at constant temperature. Calculate the work (w) if the expansion occurs against a constant pressure of 5.00 atm.
What volume of gas, measured at 690 torr and 40 degrees celcius, is required to form 29g of NaCl?
some people said that the precipitate disappeared and the solution went back to a bright orange/yellow clear colour, what is the chemical equation that describes both these reactions,
What mass of sucrose should be combined with 483 of water to make a solution with an osmotic pressure of 8.50 at 320 ? (Assume the density of the solution to be equal to the density of the solvent.)
What are the masses of CO and CO2 in the tank and what are the partial pressures of each of the three gases at 24C?
Assuming the waste heat of the engine provides all the heat necessary to melt the iceberg, how much work can this do?
If 1.00 g sodium bicarbonate and 1.00 g citric acid are allowed to react, how many grams of carbon dioxide will form?
How many liters of H2 at 23.0C and 733mm Hg are released when 1.98g of Na reacts with unlimited water?
The specific heat of aluminum is 0.21 cal g°C. How much heat is released when a 10 gram piece of aluminum foil is taken out of the oven and cools from 50 to 10 °C?
How many mole of hydrogen gas can be liberated from 85.5 moles of magnesium hydride if the process operates at 80% efficiency
calculate the specific heat capacity of zinc given that a 65.5g sample loses 2008J of heat when cooled from 100.0 degrees celcius to 21.1 degrees celcius.
NaOH + CO2 -→ Na2CO3 + H2O . If the average human body discharges 536 g of CO2 per day, how much NaOH is needed each day for each person in the spacecraft?
