## zhane2015 Group Title Please Help!! The rate of a chemical reaction normally _____. (1 point) decreases as temperature increases is slowed down by a catalyst increases as reactant concentration increases decreases as reactant concentration increases one year ago one year ago

increases as reactant concentration increases. Your in NDCDE!! LoL

2. foxhunter98 Group Title

please help me in this: Use the law of conservation of mass to explain why a chemical equation must be balanced.

3. zhane2015 Group Title

lol am i in what??

4. zhane2015 Group Title

mkayzz hold on

Foxhunter you kinda answer your own question... if mass most be conserved you can't have that some elements are just gone...

@foxhunter98 Then how did you answer my question??

10. Frostbite Group Title

I sure can... Lets consider we have a reaction called 2 A +9 B -> 5 C + 2 D. To say this in words: 2 moles of A react with 9 moles of B to create 5 moles of C and 2 moles of D. So for the calculations to work out we need to say (for a reaction assuming that all the reactants are converted): $\sum_{}^{}m(reactants)=\sum_{}^{}m(products+waist)$
