3.) a
4.) Its already balanced
5.) I belive it is 2Cr+Cl2 -> CrCl3
Answer:
please mark my answer brainliest
Explanation:
according to the formula...
density =mass/ volume...
density =21.0/2.00=10.5 g/ cm^3
Answer:
1) first order
2) second order
3) zero order
Explanation:
The curve of a first order reaction shows it to be exponential. In fact for a first order reaction, the concentration at a time t is an exponential function;
[A]t= [Ao] e^-kt
Where
[A]t = concentration at time =t
[Ao]= initial concentration
k= rate constant
t= time
For a second order reaction, the rate of reaction is directly proportional to the concentration of reactants.
For zero order reactions, rate of reaction is independent of concentration hence rate = k(rate constant)
I always thought it was a mixture but can also be a compound
