Answer:
products are copper and aluminium chloride
reactants are aluminium and copper chloride
Explanation:
products are formed at the end of a reaction
reactants are what's reacting to form the products ie the things at the start of the equation
Mass × velocity = momentum
74 x 15 = momentum
The answer is 0.25 M
Use the equation C1V1=C2V2
(.5)(100)=x(200)
x=0.25
