Determine the molecular formula of a compound which has a empirical formula of CH3 and a molar mass of 60.0 g/mol.
calculate the difference in mass that is hold by a 500.0mL flask at a temperature of 0.0°C from that at temperature of 20.0 °C? (you can assume the volume of the sample at 0.0 °C temperature =volume of the sample at 20.0°C)
The rate constant for a certain reaction is K = 8.90×10^-3 . If the initial reactant concentration was 0.950 M, what will the concentration be after 14.0 minutes.
Some KCl is dissolved in water at 25 degree Celsius, where it completely dissociates. The vapor pressure of pure water at 25 degree celsius is 28.3 mmHg.
CO (5.00 g) and CO2 (5.00 g) were placed in a 750.0 mL container at 50.0 °C. Calculate the total pressure in the container.
You are given some reactions as a. Cl2(aq) + 2NaI(aq)= I2(aq) + 2 NaCl(aq), b. Br2(l) + 2K(S)=2KBr(s), c. Pbs( s) + 4H2O2(aq)= PbSO4(s) + 4H2O(l) you just need to Indicate which element is reduced and which is oxidized in the given equations?
A sample of water 53 g with a temperature of thirty six degree celsius is combined to 250 grams of H 2 O at 91 degree Celsius in an insulated container. Determine the final temperature after thermal equilibrium is reached?
