Why aren't descriptive investigations repeatable?

In descriptive investigations, we still haven't formed any hypothesis yet so we seek information by asking question.

It's not repeatable because repeating the questions over and over again without any clue about what we want to seek is completely waste of time.

Hope this helps xox :)

Answer:

Descriptive investigations are not repeatable because they are based only on observations made at a single point in time. The results may vary at a different time. In addition, descriptive investigations do not contain variables that may indicate cause-and-effect relationships.

When an experimenter draws a conclusion that he assumes will apply to all situations set up similarly to his test situation, eve

Before making any observations, deductive reasoning relies on the formulation of a hypothesis and its subsequent substantiation.

<h3>Deductive reasoning: What does it mean?</h3>

Since the sentence states that "he assumes will apply to all instances," he is suggesting something before to carrying out any observation, which is the foundation of deductive reasoning.

A conclusion in deductive reasoning is based on the agreement of several premises that are typically taken to be true. Sometimes, top-down logic is used to describe deductive reasoning. Making logical assumptions is the foundation of deductive reasoning, which then bases a conclusion on those assumptions.

The primary distinction between inductive and deductive thinking is that the former tries to develop a hypothesis, whilst the latter aims to test an existing theory. From specific observations, inductive reasoning proceeds to

Chemical bonds form because: a. The atoms have more energy bonded together than separated b. The atoms have less energy bonded t
MrMuchimi

Answer:

A. The atoms have more energy together than separated.

Explanation:

There are several reasons why a chemical bond could take place. Adding things like heat or pressure stimulate the atoms to force a reaction to take place. But when it comes down to it, the intramolecular forces of the electrons  pull each other to form chemical bonds (represented by Valence electrons). The stronger these are, the more likely they are going to bond.

Atoms with lower forces typically don't typically bond with other atoms of lower forces.

3. The molar volume of a gas at STP occupies<br> 0 1 kilopascal<br> O ooc<br> 12 grams<br> 22.4 L
Reil [10]

The molar volume of a gas at STP occupies <u>22.4 L.</u>

Option D

<u>Explanation:</u>

To find the volume of 1 mole of a gas at STP, we use the Ideal Gas Law. It is the general gas equation which gives the relation to the measurable quantities to an ideal gas as below,

P (pressure) × V (volume) = n (number of moles) × R (the gas constant) × T (temperature in Kelvin)

STP = 1 atm of pressure and 273 K for temperature

P = 1 atm

V = ?

n = 1 mole

R = 0.0821 atm L/mol K

T = 273 K

Using the equation,

\mathrm{PV}=\mathrm{nRT}

V=\frac{n R T}{P}

By substituting the above values, in the equation,

V=\frac{1 \times 0.082 \times 273}{1}=22.38\ L

V = 22.38 L
