Answer:conversion factor

Explanation:

Answer: According to Boyle's Law, if the temperature remains constant, doubling the pressure will halve the volume of the gas.

Explanation:

The mark represents a volume of 25ml.

A Measuring cylinder, a graduated cylinder, a cylinder measuring, or a mixing cylinder is a part of various laboratory materials that are used for the measurement of the volume of liquids, chemicals, or solutions during laboratory work.

Graduated cylinders have more precise and accurate measurements than the common volumetric flasks and beakers used in the laboratory. These are of various volumes ranging from small to big.

These graduated cylinders are also used for the determination of displacement. It is a measurement of the change in a volume of water when some additional materials are added to it.

This means that a graduated cylinder can be used for the determination of solid materials by taking the difference between the initial volume of water and the new volume of water.

Therefore, in this case, the mark represents a volume of 25ml.

Conducting experiments and using the scientific method.

Explanation:

Scientists (and other people) test hypotheses by conducting experiments. The purpose of an experiment is to determine whether observations of the real world agree with or conflict with the predictions derived from a hypothesis. If they agree, confidence in the hypothesis increases; otherwise, it decreases.

The mass of a substance when given the density and volume can be found by using the formula

From the question

volume = 42 mL

density = 1.65 g/mL

The mass is

mass = 1.65 × 42

Explanation:

Answer:

Nothing can be zero, but zero isn't nothing. If someone asks you if you have money and you say "I've got nothing!" when you actually don't have a cent, then you have zero money. However, zero is a number, so it itself is something, therefore more than nothing. So technically, you do have something.

When zero is on a number line, you could classify it as nothing, but it is the number between 1 and -1. Hypothetically speaking, if you took the zero away, wouldn't the number line be the same?

Zero isn't positive or negative. The number zero on a graph, or in a coordinate can tell you where something is. Zero can be a word to describe if something is existent, or non-existent.

Answer:

Explanation:

[tex]\frac{P_{1} V_{1}}{T_{1}} = \frac{P_{2}V_{2}}{T_{2}}[/tex]

First of all cross multiply

That's

[tex]P_{1}V_{1}T_{2} = P_{2}V_{2}T_{1}[/tex]

Next divide both sides by [tex]P_{1}T_{2}[/tex]  in order to isolate [tex]V_{1}[/tex]

We have

[tex]\frac{P_{1}V_{1}T_{2}}{P_{1}T_{2}} = \frac{P_{2}V_{2}T_{1}}{P_{1}T_{2}}[/tex]

We have the final answer as

[tex]V_{1} = \frac{P_{2}V_{2}T_{1}}{P_{1}T_{2}}[/tex]

- Study definitions and examples of these and that will help.

When zinc react with sulfuric acid, then zinc sulphate is formed.  Zn + H₂SO₄ → ZnSO₄ + H₂ this reaction is replacement reaction.

One element in a molecule is replaced by another in a chemical reaction known as a single-displacement reaction, sometimes referred to as a single replacement reaction or exchange reaction.

One element in a compound is switched out for another in a single replacement reaction. In a double-replacement process, the anions or cations of two ionic compounds are switched. In a double-replacement reaction known as a precipitation, a solid precipitate is one of the products.

One ingredient replaces another comparable element in a compound in a single-replacement reaction.

Thus, option D is correct.

Explanation:

Atoms form chemical bonds with other atoms when there's an electrostatic attraction between them. This attraction results from the properties and characteristics of the atoms' outermost electrons, which are known as valence electrons.
