Problem- Find the temperature of a system after 100 g of Zn metal at 95 degrees C is immersed in 50 g of water at 15 degrees C. The specific heat capacity of zinc is 6.06 cal/molC and the specific heat caacity of water is 1.00 cal/gC
I am need of complete solution for this problem please help- me out to get right solution
how much pv work is done if 88.0 grams of c 2h 4 ethylene and 120 grams of hydrochloric acid hcl are permitted to react
Require to apply to neutralize the acidity that concluded from nitrification and determine how much CaCO 3
for 100 degrees had 2 layers which showed the seperation between ether and water. What would be the problem with running TLC to characterize the distillate samples?
Sleeping pills often contain barbital, which is weakly acidic (pKa = 8.00). For analysis of the barbital content of a sleeping pill, a titration is carried out with strong base. It takes 12.00 mL of 0.200 M base to reach the stoichiometric point.
State the formula of the conjugate base for acid HPO42. State the name of the conjugate base found in part (c). Give as a string. For instance, enter sulfate ion for SO42
In an experiment the FeSCN2+ equilibrium concentration was found to be 0.32 *10-4M in a solution made by mixing 5.00ml of 1.00*10-3 M Fe(NO3)3 solution with 5.00ml of 1.99*10-3 M HSCN solution. The H+ concentration was maintained at 0,500M
A gas cylinder containing 6.38 mol of neon has pressure of 491mmHg at 295k. If 3.22 mol helium is added at constant temp and pressure, what will be the pressure in the cylinder
Calculate the mass of water formed by the complete reaction of 935 g of propane (C3H8) with excess oxygen. (Write a balanced equation)
A student find out the mass percent of Ni is 29.7%, NH3 is 34.4%, and Cl is 35.9% in a compund containing Nickel, ammonia, and chlorine. The empirical formula of the compund is
The ratio of Fe^2+ to Fe^3+ concentrations in a solution is 1.0 x 10^3. ([Fe^2+]/[Fe^3+]) = 1.0 x 10^3. Calculate the potential of the solution relative to the saturated Ag/AgCl reference electrode, Eref = 0.204. E^0 Fe^3+/Fe^2+ = +0.771
Does an enthalpy change from saturated vapor at 450 °F to 210 °F and 7 psia represent an enthalpy increase or decrease. A volume increase or decrease
The following set of reactions can be used to produce nitric acid, HNO3. Calculate the mass of nitric acid produced from the reaction of 15.5 kg of nitrogen gas with excess hydrogen gas. Each reaction in turn has an excess of the second reactant a..
