Chlorine dioxide gas is used as a commercial bleaching agent. One method of preparing ClO2 is the reactiong of chlorine gas with sodium chlorite as:
Cl2(g) + 2 NaClO2(s) ---> 2 ClO2(g) + 2 NaCl(s)
If you allow 10.0 g of sodium chlorite to react with 2.00 L of chlorine at 1.50 atm and 21 degrees Celsius, what would be the volume of the chlorine dioxide produced and measured under the same conditions of temperature and pressure?
a. 4.0 L
b. 3.5 L
c. 2.5 L
d. 1.8 L
e. 1.5 L
Cyanogen is a gas which contains 46.2 % C and 53.8 % N by mass. At a temperature of 25oC and a pressure of 750 mmHg, 1.50 g of cyanogen occupies 0.714 L.
Calculate the amount of heat (calories) absorbed when 50.0g of water at 20deg. Celsius spreads over your skin and warms to body temperature, 37deg. celsius.
the Standard Gibbs energy change associated with this oxidation reaction is ca. 0. kJ/g.
