Explanation:
Answer:
A. The total mass of the reactants in a reaction equals the total mass of the product(s).
Explanation:
The law of conversation of matter tells us that in a chemical reaction, matter is never created or destroyed, it's simply converted from one form to another. So the mass of reactants should always equal the mass of the products in a chemical reaction.
Answer:
Look for extra things to do, small details, until you find a big enough one to go off that to continue
Explanation:
n/a
14 since K has 1 valence but there’s two so 2 valence for k and oxygen has 6 but there’s two so 12
Answer:
Sln
n=m/mr
n=25/100
n=0.25mole of Caco3
Malality =number of moles/volume (divided by number of moles both sides)
volume =Malality /number of moles
v=0.125/0.25
v=0.500L
I hope this help
