1 mol of Ca(OH)2 is placed in 2 L of water and stirred. At equilibrium, at a certain temperature, 0.0180 mol of Ca(OH)2 dissolves. What is Keq? (Assume, the volume of the solution is the same as the initial volume of water.)
Keq=[Ca2+)[OH]^2
Nitrogen gas when combined with hydrogen gas forms ammonia gas according to the following equation N2(g)+3H2(g)->2NH3(g) deltaHrxn=-56 kJ.
7.80 g of CuNO3 is dissolved in water to make a 0.720 M solution. What is the volume of the solution? Answer should be in mL.
When the reaction 2 H2S g ~ PCl3 + Cl2 is carried out at 1065 degrees celcius, Kp = 0.012. Starting with pure H2S at 1065degrees, what must the initial pressure of H2S be if the equilbrated mixture at this temperature is to contain 0.250 atm of H2..
Lidocaine is thought to bind to receptors in its methylated form. identify in writting the atoms or groups in the compound that could be involved in its binding to a receptor via- hydrogen bonding (1 example)
A 0.484g sample of impure NH4Br is treated with 25.00mL of 0.2050 M NaOH and heated to drive off the NH3. The unreacted NaOH in the reaction mixture after heating required 9.95mL of 0.0525 M H2C2O4 to neutralize.
If 72.4 kJ of heat is supplied to a 842 g block of metal, the temperature of the metal increases by 9.0°C. Calculate the specific heat capacity of the metal in J/g·°C.
How much A would have been extracted into ether if the orginal aqueous solution had been extracted once with a 500-mL portion of ether? What percentage of A would have been extracted by the ether?
The pH of a 0.010 mol L-1 solution of a weak monoprotic acid is 2.09 at 25oC. What is the pKa for this acid
What is the molarity of the hydrochloric acid solution. A sample of natural gas is 85.2% methane, CH4, and 14.8% ethane, C2H6, by mass. What is the density of the mixture at 18 ? and 771 mmHg
An "empty" container is not really empty if it contains air. How may moles of nitrogen are in an "empty" two-liter cola bottle at atmospheric pressure and room temperature (25 C)? Assume ideal behavior. the partial pressure of nitrogen in air at 1..
ammonia undergoes autoionization by the transfer of a proton: 2NH3 NH4+ + NH2-, K = 1×10^-33 at -50°C Since ammonia is better proton acceptor than water, the ionization of acids is relatively enhanced in liquid ammonia. For example, acetic acid i..
Silver chloride will precipitate out of solution, leaving an unsaturated solution of AgCl. D) Nothing will happen since NaCl and AgNO3 are both soluble compounds.
