A common laboratory reaction is the neutralization of an acid with a base. When 60.0 mL of 0.25 M nitric at 24.5 degree C is added to 60.0 mL of 0.275 M NaOH at 24.5 degree C in a coffee cup calorimeter, the temperature of the mixture rises to 30.5 degree C. The specific heat of the solution is 4.15 J/g degree C and its density is 1.025 g/mL. The heat capacity of the calorimeter is 25.6 J/degree C. What is the heat of the reaction per mole of acid?
When 5.00 × 1022 molecules of ammonia react with 4.00 × 1022 molecules of oxygen, how many grams of nitrogen gas are produced? 4NH3(g) + 3O2(g) → 2N2(g) + 6H2O(g)
For the reaction BrO3- + 5Br-+ 6H+ ? 3Br2 + 3H2O at a particular time, -?[BrO3-]/?t = 1.5 ? 10-2 M/s. What is -?[Br-]/?t at the same instant
What would be the speed of the following particles if they had the same wavelength as a photon of green light (? = 500.0 nm)? Proton (mass = 1.673 × 10-24 g) Neutron (mass = 1.675 × 10-24 g) Electron (mass = 9.109 × 10-28 g) Alpha particle (mass =..
