A 25.0 mL bubble is realeased from a diver's air tank at a pressure of 4.00 atm and a temperature of 11 C. what is the volume of the bubble when it reaches the ocean surface where the pressure is 1.00 atm and the temperature is 18 C?
a 6.0-g sample of [Ni(H2O)6]Cl2 is dissolved in aqueous solution. If an excess of ethylenediamine (en) is added to the solution, solid [Ni(en)3]Cl2*2H2O forms. What is the theoretical yield of product from the reaction?
What is the value of x in the formula for the hydrate? (hint: remember that x represents the ratio of moles of H2O to moles of hydrate compound, and that moles of hydrate compound equals the moles of anhydrous compound)
What volume of oxygen is required to burn completely 401 cm3 (centimeters cubed) of butane, C4H10 (All substances are gases measured at the same temperature and pressure.)
What is the total volume of gaseous products, measured at 332°C and 732 torr, when an automobile engine burns 100. g C8H18 (a typical component of gasoline)? Answer needs to be in Liters
What mass of AlCl3 can be formed from 5.000 mol NiCl2 and 2.000 mol Al?
A volume of 80.0 ml of H2O is initially at room temperature (22.0 C). A chilled steel rod at 2.00 C is placed in the water. If the final temperature of the system is 21.1 C , what is the mass of the steel bar?
What volume of oxygen gas at 25 degrees Celcius and 1.00 atm is produced from the decomposition of 22.33 mL of a 30.0% (by mass) solution of hydrogen peroxide?
