An ideal gas is allowed to expand from 8.40L to 12.6L at constant temperature. By what factor does the volume increase. The pressure will increase by same factor or decrease by same factor.
what is the order of increasing stability: Li2,Li2+,Li2-?
Proceeds at a certain temperature until the partial pressures of H2O, H2, and O2 reach 0.0800 atm, 0.00500 atm, and 0.00200 atm respectively.
If the Ksp of Fe(OH)2 is 7.9 × 10-16, what is the maximum [Fe2+] that can coexist with these solutes in the solution?
Calculate the % yield of Al2(SO4) from the reaction: 2Al(OH)3(s) + 3H2SO4(aq) -> Al2(SO4)3(s) + 6H2O(l) given that 205 g of Al(OH)3 react with 751 g of H2SO4 to yield 252 g Al2(SO4)3.
80.0 of is initially at room temperature (22). A chilled steel rod at 2 is placed in the water. If the final temperature of the system is 21.5, what is the mass of the steel bar?
You dissolve 650.0 g of sugar (C12H22O11) in 726 mL of water. The density of wat is 1.00 g/mL.
the addition of bromine to an equimolar mixture of cis- and trans-2-butene generates only three stereoisomers. Explain.
With what minimum speed must Fran leave the ground in order to lift her center of mass 1.95 m and cross the bar with a speed of 0.70 m/s?
What is the Ce 3+ concentration in a solution formed by combining 50.0 mL of 0.0500 M Ce 3+ with 50.00 mL of 0.150 M IO3-? The solubility-product constant for Ce(IO 3 )3 = 3.2 x 10 E-10.
Consider a glass of 171 mL of water at 29°C. Calculate the mass of ice at -15°C that must be added to cool the water to 10°C after thermal equilibrium is achieved.
the resulting mixture has (pb2+)i=1.0x10^-3M, (so4^-2)i=1.0x10^-4 for pbso4 ksp=1.3x10^-8. compare qsp to ksp and decide whether a precipitate will form.
