Answer : Option C)
6.3 X .
Explanation : Given is the concentration of benzoic acid is 0.200 M, now only one monoprotic acid ion is getting separated from it [
.
So, the reaction will be as,
⇔
+
.
We can use the ICE method for calculation,
The molar concentration of
is 0.200 M and the [
is 3.55 X
.
So here on reactant side we get, (0.2 - 3.55 X
) = 0.196
on the product it remains as 3.55 X
.
So,
= (3.55 X
) X (3.55 X
) / 0.196
We will get
as
6.42 X which is close to 6.3 X .
Answer:
what's the answer choices
I would do the nervous system because nerves are what makes you feel everything around you and in order for you to be able to react you need the nervous system why? <span>The nervous system is the highway along which your brain sends and receives information and feelings about what is happening in the body and around it on the outside. This highway is made up of billions of nerve cells, or neurons which join together to make nerves. This is very important for the human to be able to live!</span>
The empirical formula of the compound containing 0.64 g of copper, 0.32 g of sulphur and 0.64 g of oxygen is CuSO₄
From the question given above, the following data were obtained:
Mass of Cu = 0.64 g
Mass S = 0.32 g
Mass of O = 0.64 g
<h3>Empirical formula =? </h3>
The empirical formula of the compound can be obtained as follow:
Cu = 0.64 g
S= 0.32 g
O = 0.64 g
Divide by their molar mass
Cu = 0.64 / 63.5 = 0.01
S= 0.32 / 32 = 0.01
O = 0.64 / 16 = 0.04
Divide by the smallest
Cu = 0.01 / 0.01 = 1
S= 0.01 / 0.01 = 1
O = 0.04 / 0.01 = 4
Therefore, the empirical formula of the compound is CuSO₄
