What is the total number of liters of O2(g) produced from the complete decomposition of 0.500 mole of KClO3(s)?
Ammonium nitrate is a common ingredient in chemical fertilizers. Use the reaction shown to calculate the mass of solid ammonium nitrate that must be used to obtain 0.200 L of dinitrogen oxide gas at STP.
A total of 2.00 moles of a compound is allowed to react in a foam coffee cup that contains 127g of water. The reaction caused the temperature of the water to rise from 21.0 to 24.7 celcius .
A 380. mL container holds 0.146 g of Ne and an unknown amount of Ar at 35°C and a total pressure of 630. mmHg. Calculate the moles of Ar present.
If the acid dissociation constant, Ksuba, for an acid HA is 8 x 10^-4 at 25 degree C, what percent of the acid is dissociated in a 0.50 M solution of HA at 25 degree C?
