Match the following items. Match the items in the left column to the items in the right column. 1. general or nonspecific observ
ation best fit curve 2. educated guess quantitative 3. when two variables change in the same direction, one remaining larger than the other by the same factor theory 4. "measured" observation control 5. standard, reference data, or experiment qualitative 6. a presently accepted explanation of how something happens law 7. a statement that explains what something does under the same conditions hypothesis 8. a curve drawn to average the data's deviations direct relationship
1 answer:
when column B is like the attached pic: (missing in your question)
so the matches will be like that:
1- Qualitative :
as Qualitative is a general or nonspecific observation, they also don't require
measurements and even can't be measured, that is because of the reality is
being approximated only. It describes qualities and uses opinion
2- Hypothesis :
as a hypothesis is an educated guess quantitative, and it is a prediction stated
in " If and then " form. a hypothesis to be valid need a research such as:
-Encyclopedia & state and local research facilities & scientific journals.
3- Direct relationship:
as a Direct relationship is when two variable change in the same direction,
and one remaining larger than the other by the same factory.
- this is a type of a relationship in which there is a change with one variable, and corresponding with the change in the other. and because this corresponding change with the other variable in the same direction so it refers to a positive relationship.
4- Quantitative:
as Quantitative is a measured observation, It's an information or data based
on quantities obtained. And using numbers, equipment and standard units.
5- Control :
as control is standard, reference data or experiment qualitatively. this is what
you compare your experimental results to. This is for comparing results, it
used as a standard for comparison and use baseline measurements to use in
the comparing.
6- Theory :
as Theory is a presently accepted explanation of how something happened.
Scientifically acceptable general principles to explain phenomena. It the
general or abstract principles of the science. for example the wave theory of
light.
7- Law :
as a law is a statement that explains what something does under the same
conditions. when we take about law in science, it is a general rule to explain
the observations in the form of a mathematical statement. Scientific law may
be stated in words or expressed as a mathematical equations.
8- Best fit curve:
as best fit curve is a curve drawn to average the data's deviations direct
relationship. It is a process of constructing a curve that has best fit to a
series of data points.
so the matches will be like that:
1- Qualitative :
as Qualitative is a general or nonspecific observation, they also don't require
measurements and even can't be measured, that is because of the reality is
being approximated only. It describes qualities and uses opinion
2- Hypothesis :
as a hypothesis is an educated guess quantitative, and it is a prediction stated
in " If and then " form. a hypothesis to be valid need a research such as:

and one remaining larger than the other by the same factory.
- this is a type of a relationship in which there is a change with one variable, and corresponding with the change in the other. and because this corresponding change with the other variable in the same direction so it refers to a positive relationship.
4- Quantitative:
as Quantitative is a measured observation, It's an information or data based
on quantities obtained. And using numbers, equipment and standard units.
5- Control :
as control is standard, reference data or experiment qualitatively. this is what
you compare your experimental results to. This is for comparing results, it
used as a standard for comparison and use baseline measurements to use in
the comparing.

Answer : The heat of the reaction is -221.6 kJ
Explanation :
Heat released by the reaction = Heat absorbed by the calorimeter
where,
= heat released by the reaction = ?
= heat absorbed by the calorimeter
= specific heat of calorimeter =
= change in temperature =
Now put all the given values in the above formula, we get:
As,
So,
Thus, the heat of the reaction is -221.6 kJ
