False
nuclear fusion produces more energy than a nuclear fission reaction.
Answer:
The answer to your question is:
Explanation:
Ionic compound is formed when a metal and a nonmetal are attached.
If we have MgX₂, that means that the nonmetal must have a valence of -1.
From the list the nonmetals with a valence of -1 are:
Bromine(Br) and fluorine(F).
Behavioral Adaptation is something that is natural in animals that are used for survival. Example: Birds Migrating north during the winter.
Answer:
(1) order = 2
(2) R = K [A]²
Explanation:
Given the reaction:
A--------->Product
The rate constant relation for the reaction is given as:
R(i) = K [A]............(*)
Where R(I) is rate constant at different concentration of A.
Taking the rate constant as R1, R2 and R3 for the different concentrations respectively. Then the following equations results
0.011 = K [0.15] ⁿ.........(1)
0.044 = K [0.30]ⁿ .......(2)
0.177 = K [0.60]ⁿ .........(3)
Dividing (2) by (1) and (3) by (1)
Gives:
0.044/0.011 = [0.3/0.15]ⁿ
4 = 2ⁿ; 2² = 2ⁿ; n = 2
Similarly
0.177/0.011 = [0.60/0.15]ⁿ
16.09 = 4ⁿ
16.09 = 16 (approximately)
4² = 4ⁿ ; n = 2
Hence the order of the reaction is 2.
The rate law is R = K [A]²
