Answer:

6. Scientific inquiry - D

7. Hypothesis - E

8.  Control group - G

9. Experimental group - A

10. Independent variable - B

11. Dependent variable - H

12. Scientific theory - C

13. Scientific law - F

Explanation:

6. Scientific inquiry - D

Scientific inquiry is the study of the explanation for the natural world phenomenon and it requires many scientific steps.

7. Hypothesis - E

A hypothesis is a possible explanation for a phenomenon or problem. It is tested in order to see if true or not.

8.  Control group - G

The control group in a scientific experiment is a group of subjects did not get the treatment and left alone.

9. Experimental group - A

The experimental group is another hand group of subjects that gets treatment and shows the effect of the variable being tested.

10. Independent variable - B

Independent variables change or manipulated during an experiment and cause a response from the dependent variable.

11. Dependent variable - H

The dependent variable is a variable that is dependent on independent variables and changes in the independent variable.

12. Scientific theory - C

A well-tested explanation for experimental results with the scientific process.

13. Scientific law - F

This describes an observed pattern in nature

Relative humidity is described as: Group of answer choices a basically unused concept when it comes to weather topics. the amoun
Bad White [126]

Correct answer:

The relative humidity is best described as the amount of water vapor in the air at a given temperature expressed as a percentage of the water vapor capacity of the air.

What is relative humidity?

The ratio of the current absolute humidity to the highest absolute humidity is known as relative humidity (which depends on the current air temperature).

Water vapor is also measured by relative humidity, which is stated as a percentage but RELATIVE to the air's temperature. In other words, it is a comparison between the amount of water vapor that is actually present in the air and the maximum amount of vapor that is possible for the air at the current temperature.

With the same quantity of absolute/specific humidity, air will have a HIGHER relative humidity if it is cooler and a LOWER relative humidity if it is warmer because warm air may contain more water vapor (moisture) than cold air. The actual amount of moisture (absolute humidity) in the air is what we "feel" outside.

When solid ammonium carbamate sublimes, it dissociates completely into ammonia and carbon dioxide according to the following equ
Harlamova29_29 [7]

<u>Answer:</u> The equilibrium constant for the given equation is 0.0315

<u>Explanation:</u>

We are given:

Total pressure in the container = 0.596 atm

The given chemical equation follows:

              N_2H_6CO_2(s)\rightleftharpoons 2NH_3(g)+CO_2(g)

<u>Initial:</u>              -

<u>At eqllm:</u>         -                   2x           x

Evaluating the value of 'x'  

\Rightarrow (x+2x)=0.596\\\\x=0.199

The expression of K_p for above equation follows:

K_p=p_{CO_2}\times (p_{NH_3})^2

The partial pressure of pure solids and pure liquids are taken as 1 in the equilibrium constant expression.

Putting values in above expression, we get:

K_p=(0.199)\times (2\times 0.199)^2\\\\K_p=0.0315

Hence, the equilibrium constant for the given equation is 0.0315
