Answer:
It would be Container 3
Explanation:
Each of the containers has the same amount of salt. Salinity refers to salt level. Since the question is asking for the container with the greatest salinity, you are looking for the container with the least water (because it will be the saltiest out of all of them). Container 3 has the least water.
Hope this helps :)
Answer:
The rate of reaction changes by a factor 6.
Explanation:
Given the reaction is first order.
Let us assume the initial concentration of 
is 
and the initial concentration of 
is 
.
So, we can write the rate of the reaction as
![R=k[A][B]](https://tex.z-dn.net/?f=R%3Dk%5BA%5D%5BB%5D)
Where,
is the rate of reaction. And 
is the rate constant.
Also, the initial concentration of has been increased by 
, and the initial concentration of was increased by factor 
.
So, we have
![R'=k[1.5A][4B]\\R'=6k[A][B]\\R'=6R](https://tex.z-dn.net/?f=R%27%3Dk%5B1.5A%5D%5B4B%5D%5C%5CR%27%3D6k%5BA%5D%5BB%5D%5C%5CR%27%3D6R)
We can see the rate of reaction changes by a factor 6.
Answer:
Percent yield of hydrogen is 87.096%
Explanation:
Theoretical yield = 155g
Experimental yield = 135g
% yield = [experimental yield / theoretical yield] * 100
% yield = (135 / 155) * 100
% yield = 0.87096 * 100
% yield = 87.096 %
The percentage yield of hydrogen is 87.096%
Charge = number of proton - number of electron = 18-22 = -4
SO, OPTION A IS YOUR ANSWER........
