When a 2.00-g strip of zinc metal is placed in an aqueous solution containing 2.50 g of silver nitrate, the reaction is
Zn(s) + 2 AgNO3(aq) 2 Ag(s) + Zn(NO3)2(aq)
(a) Which reactant is limiting? (b) How many grams of Ag form?
(c) How many grams of Zn(NO3)2 form? (d) How many grams of
the excess reactant are left at the end of the reaction?

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.

hope this contact me for more questions if you'd like: )
