What is the mass of silver (107.87 g/mol) produced by the reaction of 3.00 moles of copper with 3.00 moles of silver nitrate?Cu + 2AgNO3→Cu(NO3)2+ 2Ag

323.61 g of will be produced

Explanation:

The given balanced chemical reaction is :

According to stoichiometry :

2 moles of require 1 mole of

Thus 3.00 moles of   will require=  of

Thus is the limiting reagent as it limits the formation of product.

As 2 moles of give =  2 moles of

Thus 3.00 moles of give =  of

Mass of

Thus 323.61 g of will be produced from the given moles of both reactants.

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.
