inna [77]

Considering the Boyle's law, the new pressure of the sample is 1,776 mmHg.

<h3>What is Boyle's law</h3>

Boyle's law establishes the relationship between the pressure and the volume of a gas when the temperature is constant.

Boyle's law states that the volume occupied by a given mass of gas at constant temperature is inversely proportional to the pressure. This means that if the pressure increases, the volume decreases, while if the pressure decreases, the volume increases.

Boyle's law is expressed mathematically as:

P×V=k

Now it is possible to assume that you have a certain volume of gas V1 which is at a pressure P1 at the beginning of the experiment. If you vary the volume of gas to a new value V2, then the pressure will change to P2, and the following will be true:

P1×V1=P2×V2

<h3>New pressure</h3>

In this case, you know:

P1= 740 mmHg
V1= 3 L
P2= ?
V2= 1.25 L

Replacing in Boyle's law:

740 mmHg× 3 L=P2× 1.25 L

Solving:

P2= (740 mmHg× 3 L) ÷ 1.25 L

P2= 1,776 mmHg

Finally, the new pressure of the sample is 1,776 mmHg.

If I have a +2 oxidation number do I give up or accept electrons?

ivanzaharov [21]

Answer:

I will give up the electrons

Explanation:

Consider the following rules:

1. An atom loses electrons if its oxidation number is positive.

2. An atom gains electrons if its oxidation number is negative.

3. An atom neither gains nor loses electrons if its atomic number is zero.

As I have an oxidation number $+2$ that is oxidation number is positive, so, I will give up electrons.

Antoinc Laurent Lavoisicr's contribution to chemistry was. a.the law of conservation of mass.

Ulleksa [173]

The answer for the following question is explained below.

The option for the following answer is "d".

Explanation:

The phlogiston theory of combustion:(Greek word phlogiston means <u><em>"BURN"</em></u>)

Phlogiston theory states that phlogisticated substances are the substances that contain phlogiston and dephlogisticate when burned.

Dephlogisticating is the process of releasing stored phlogiston,which is absorbed by the air.

Growing plants then absorb this phlogiston,which is why air does not spontaneously combust and also plant matte burns as well as it does.

The prevailing theory was that flammable materials contained a substance called phlogiston that was released during the combustion.

For example:

phlogiston was transferring into the surrounding air.

A periodic table allows you to easily compare the properties of one element ( or a group of element to another element or group

AfilCa [17]

The statement above is TRUE.
The periodic table refers to the table of chemical elements, in which the elements are arranged in order of their atomic numbers in such a way that, similar elements appear in vertical columns. Elements in the same column usually have similar atomic structures and similar chemical properties. Thus, the periodic table allows one to easily compared the properties of one element to that of another one depending on the placement of the elements in the periodic table.<span />
