Answer:
<h3>The answer is 32 g/cm³</h3>
Explanation:
The density of a substance can be found by using the formula

From the question
mass = 768 g
volume = 24 cm³
We have

We have the final answer as
<h3>32 g/cm³</h3>
Hope this helps you
Answer:
D
Explanation:
They are renewable energy sources
Explanation:
(a) As the given chemical reaction equation is as follows.

So, when we double the amount of hypochlorite or iodine then the rate of the reaction will also get double. And, this reaction is "first order" with respect to hypochlorite and iodine.
Hence, equation for rate law of reaction will be as follows.
Rate =
(b) Since, the rate equation is as follows.
Rate =
Let us assume that (
)
Putting the given values into the above equation as follows.

K =
=
Hence, the value of rate constant for the given reaction is
.
(c) Now, we will calculate the rate as follows.
Rate =
=
= 
Therefore, rate when
M and
M is
.
