The most appropriate word among the group of answer choices to fill in the blank is: a. Random sample surveys.

Sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.

The various types of sampling used by researchers includes the following;

Systematic sampling.

Convenience sampling.

Stratified sampling.

Cluster sampling.

Random sampling.

A random sample survey is also referred to as a simple random sample (SRS) and it can be defined as a sampling technique that involves randomly selecting a subset of a larger population. Also, any result obtained through the use of a random sample survey can be generalized and applied to a larger population.

In conclusion, scientists and researchers prefer random sample surveys because their results can be generalized to a larger population.

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

Harlamova29_29 [7]

Answer: The equilibrium constant for the given equation is 0.0315

Explanation:

We are given:

Total pressure in the container = 0.596 atm

The given chemical equation follows:

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

Initial: -

At eqllm: - 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
