4 KO2 + 2 H2O + 4 CO2 4 KHCO3 + 3 O2
How many grams of KO2 are needed to react completely with 7.328 g of CO2.
Why can't i reduce carboxylic acid using sodium borohydride while lithium aluminium hydride can do the same thing.
Calculate the cell potential after the reaction has operated long enough for the [Al3+] to have changed by 0.32 mol/L. (Assume T = 25°C.)
it is found that 1.431g of element x ciontains 7.509 *10^21 atoms. calculate the atomic mass of x

Calculate the theoretical yield of C2H5Cl when 124 g of C2H6 reacts with 219 g of Cl2 , assuming that C2H6 and Cl2 react only to form C2H6Cl and HCl.
A 397 mL container holds 0.146 g of Ne and an unknown amount of Ar at 35°C and a total pressure of 639 mmHg. Calculate the moles of Ar present
A 41 kg person drinks 280. g of milk, which has a "caloric" value of approximately 3.0 kJ/g. If only 18% of the energy in milk is converted to mechanical work,
How much H2O is produced when 20000 g of C2H2 burns completely? Answer in units of grams
compute the enthalpy change, (Delta H), for this reaction per mole of A. suppose that the specific heat =[4.18J/(g*Degrees C) and density=1.00(g/mL)?
meteorological balloon contains 375 L of helium at 29°C and 0.928 atm. If the volume of the balloon can vary according to external conditions, what volume would it occupy at an altitude at which the temperature is -40°C and the pressure is 0.031 a..
Explain why hydrogen which has one electron in its lowest state, should in principle be a metallic conductor in its solid state whereas helium which has two electrons in its lowest energy state should be an insulator.
