Answer: They are both non polar molecules compounds although water is a polar molecule compound. There are no significant attractions.
Answer : The correct option is, (A) 51.1%
Explanation :
Mass percent : It is defined as the mass of the given component present in the total mass of the compound.
Formula used :

First we have to calculate the mass of
and
.
Mass of
= 18 g/mole
Mass of
= 7 × 18 g/mole = 126 g/mole
Mass of
= 246.47 g/mole
Now put all the given values in the above formula, we get the mass percent of
in
.

Therefore, the mass percent of
in
is, 51.1%
Answer:
Answer would be 4/2
Explanation:
A is the best answer choice because it was between A and D but 2 is not the denominator so it couldnt be D
Answer:
C.
Explanation:
We are given that
Initial concentration, ![[A]_o=4.3 M](https://tex.z-dn.net/?f=%5BA%5D_o%3D4.3%20M)
First half life,
minutes
Second half life,
minutes
We have to find K.
The given reaction is zero order reaction.
We know that for zero order reaction
![t_{\frac{1}{2}}=\frac{[A]_o}{2k}](https://tex.z-dn.net/?f=t_%7B%5Cfrac%7B1%7D%7B2%7D%7D%3D%5Cfrac%7B%5BA%5D_o%7D%7B2k%7D)
Using the formula



Hence, option C is correct.
