Answer:
Independent variable- nature of irrigation water
Dependent variable- height of the plants
Explanation:
In every study, there must be an independent and a dependent variable. The dependent variable changes its value as the value of the independent variable changes.
When the nature of irrigation water is manipulated, the height of the plant changes accordingly. This implies that the nature of irrigation water (microwaved or tap water) is the independent variable while the height of the plant (the response) is the dependent variable.
Explanation:
The given data is as follows.
= 0.042 M, for
According to the given situation acts as a base.The reaction equation will be as follows.
Relation between and are as follows.
=
=
Also,
Let us take = x
So,
x =
=
pOH = - log
= - log ()
= 4.99
As it is known that pH + pOH = 14
so, pH + 4.99 = 14
pH = 9.01
Thus, we can conclude that pH of the solution is 9.01.
Answer:
<em>a) The variable that we will change will be the different liquids.</em>
<em>b) The variable which will be kept same will be the ramp angle, the time for measuring in each experiment and the heat. </em>
Explanation:
In a scientific experiment, an independent variable is a variable which is changed by the researcher so that its effect on the dependent variable can be studied.
A dependent variable is a variable which is under study and might be influenced by changes in the independent variable.
It is best to study the effect of a single independent variable at a time so that we can easily infer the results.
<u><em>In the scenario discussed in the question, we would change the different liquids so that the time taken by each liquid to flow down the ramp can be studied.</em></u>
<u><em>We will keep the ramp angle, the time (of each experiment) and heat for each of the experiments the same so that a just conclusion can be drawn.</em></u>
