Description

1. Obtain hydroxides NaOH and Fe (OH) 2 known methods.
2. Do not settle accounts, calculate the sign of the change in entropy for the reaction:
a) 2CH4 (g) ↔ C2H2 (g) + 3H2 (g)
b) N2 (g) + 3H2 (g) ↔ 2NH3 (g)
c) 2C (graphite) + O2 (g) ↔ 2CO (g)
3. How many grams of metal, the molar mass equivalent is equal to 12.15 g / mol, is reacted with 112 cm3 of oxygen under normal conditions.
4. heterogeneous reactions C (j) + CO2 (g) ↔ 2CO (g) determines the course of all processes carbothermal production of metals from oxides. How many times to change the speed of this reaction with a decrease in pressure of four times? The answer to confirm calculations.
5. Recovery of vapors WCl6 hydrogen - a method of producing tungsten WCl6 (g) + 3H2 (g) ↔ W (a) +
