I2 is produced by the reaction of 0.4235 mol of cucl2 according to the following equation: 2cucl2+4ki 2cui+4kcl+i2

React with 0.847 mol of KI

Produce:

0.4235 mol of CuI

0.847 mol of KCl

0.21175 moles de I2

Explanation:

2CuCl2 + 4KI    produce 2CuI + 4KCl  + I2

The stoichiometric coefficients give us the relationship in moles:

2 mol of CuCl2 react whit4 mol of KI

0.4235   mol of CuCl2 react whit...X=   0.847mol of KI

2 mol of CuCl2 produce2 mol of CuI

0.4235   mol of CuCl2 produceX=0.4235 mol of CuI

2 mol of CuCl2 produce4 mol of KCl

0.4235   mol of CuCl2 produceX= 0.847 mol of KCl

2 mol of CuCl2 produce 1 mol of I2

0.4235   mol of CuCl2 produceX= 0.21175 moles de I2

If you need to know the mass that is produced you just have to multiply the moles by the molecular mass

altitude, density, pressure

air gets less dense the higher the altitude and also the air pressure is less as altitude rises.
