Iron metal reacts with chlorine gas according to the equation: 2fe(s) + 3cl2(g) →2fecl3(s)if 25.6 g of iron react completely, how much fecl3 will be formed?

74.05g/mol

Explanation:

Using mole concept

2mole of 56g of Fe will produce 2mole of 162g/mol of FeCl3

Therefore 25.6g of Fe will produce

25.6g * 162g/mol divided by 56g

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
