The formation of ClF3(g) is exothermic: Cl2(g) 3 F2(g) 2 ClF3(g) heatPredict the effect on the equilibrium decreasing the volume of the flask containing the reaction. Answer by choosing:

See explanation

Explanation:

The reaction equation is;

Cl2(g) + 3 F2(g) >2 ClF3(g)

If the volume of the flask containing the reactants in this exothermic reaction is decreased, the equilibrium position will shift towards the right hand side.

This is because, decrease in the volume of the reaction system drives the equilibrium in the direction producing the lower total volume which in this case is the forward direction

Hence when the volume of the reaction system is decreased, more ClF3 is obtained because the equilibrium position shifts towards the right hand side.

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
