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:
Explanation:
Aluminium hydroxide () is a base and hydrobromic acid (HBr) is a strong acid.
Hence an acid-base reaction occurs between and HBr
Balanced molecular equation:
Balanced total ionic equation:
Balanced net ionic equation:
(net ionic equation is written by removing common ions present in both side of total ionic equation)
Answer:
In the absence of ethylene hormone,growth and development of plant do't takes place.
Explanation:
Ethylene is an important plant hormone that in produced by plants for the purpose of growth, development and respond to stress for various purpose through out it's life cycle.
They are volatile and are also required in the field of agriculture for ripening of fruits, seed germination, root stem development,sex determination etc.
Over use of ethylene may provide harmful impact on the plant as it spoil the products.
The answer of this question is Oxygen
