Answer:
Both are equal
Explanation:
Mass of starting material i.e Aluminium is 
grams
The weight of oxygen is 
There are 4 atoms of aluminium and 3 atoms of oxygen
Thus, the total mass of starting material is
mass of one atom of aluminium 
mass of one atom of oxygen
grams
Mass of new substance is also equal to
mass of one atom of aluminium mass of one atom of oxygen
grams
Answer:
The rate law is [B]
Explanation:
In Trials 1 and 2, the concentration of B changes and A is the same so you can see how changes in B affect the rate. In this case, 0.300/0.150=2 and 7.11 x 10^-4 / 3.56 x 10^-4= 2. Since there 2^1=2, we can say that the reaction order of B is 1.
Similarly, if we look at trials 2 and 3, the concentration of B is constant, while A is changing. In this case, the rate has not changed at all with a change in concentration of A, so this means that A has 0 order.
Therefore, the rate law is just [B].
Answer:
There's No Answer Im Sorry
The control group is the plant without the music because nothing is being done to it. while the experimental group is the plant with music because you are testing it in a different environment (the music).
