13.75mL of a 0.165M solution of aqueous hydrochloric acid were required to fully neutralize a sample of aqueous calcium hydroxide. After the neutralization is completed, all of the water is evaporated to reveal a white crystalline solid. Calculate the number of grams of this solid that are formed.
The final temperature of the water and metal was 25.0 C. Assuming no heat is lost to the surroundings,calculate the specific heat of the metal and estimate its atomic weight
di ethyl ethal is a volatile, highly inflammable organic liquid that is used mainly as a solvebt. the vapour pressure of di ethyl ethal is 4.01mmHg at 18 degree celcius.
Complete and balance the following chemical equation using the smallest whole number coefficients. Assume the reaction takes place in acidic aqueous solution. Use H + to balance charge, not H 3 O +
Nitration of chlorobenzene (C6H5Cl) occurs- faster than nitration of benzene and gives a mixture containing mostly o-and p-chlorobenzene
In combustion studies of the use of H2 as an alternative fuel, HO is sometimes formed in flames by the reaction, H(g) + 1/2 O2(g) HO(g) Use the data below to calculate the value of Kc
in a laboratory, 6.82 g of Sr(NO3)2 is dissolved in enough water to form 0.500 L of solution. A0.100-L sample is 0.0245 M solution of Na2CrO4.
When an ion-selective electrode for X was immersed in 0.0490 M XCl, the measured potential was 0.0470 V. What is the concentration of X when the potential is 0.0620 V?
A water sample contains 118mg/L of bicarbonate ion, 19mg/L of carbonate ion, and has a pH of 9.5. What is the alkalinity of this water expressed as mg/L of CaCO3
The solubility product of PbBr2 is 8.9x10^-6. Determine the molar solubility in the following. (a) pure water (b) 0.20 M KBr solution (c) 0.15 M Pb(NO3)2 solution
calculate the volume of carbon dioxide, measured at 273 k and 1.01 x 10 5 Pa, which would be produced when 1.25 g of calcium carbonate reacts completely with the hydrochloric acid.
One Way of purifying gaseous H2 is to pass it under high pressure through the holes of a metal's crystal structure. Palladium, which adopts a cubic closest packed structure
Calculate the Standard Enthalpies & Standard Entropies for each reactant & product at the temperature given first, then determine the ?H°rxn and ?S°rxn at 1600 K Zr(beta) + O2 = ZrO2(beta) Other information:
