Answer:
1. First
2. Third
3. Fourth
4.remain the same as
Explanation:
Given the reaction equation;
Rate= k[A] [B]^3
We can see that the order of reaction is first order with respect to reactant A and third order with respect to reactant B. This gives an overall fourth order reaction.
If the concentration of A is doubled and that of B is halved. The rate of reaction remains the same.
Answer:
There are 20 atoms in hydrogen.
Explanation:
Multiply Coefficient with Hydrogens subscript. In this case the coefficient is a 4 so you multiply that with Hydrogens subscript which is 5. So it would be (4)(5)=20
