How do protons, neutrons, and electrons differ in terms of their electrical charges and
locations within the atom?

Answers

Answer:

Protons and Neutrons are large particles and are densely compacted into the nucleus of the atom. Protons are electrochemically positive in charge and the Neutrons are electrochemically neutral in charge. ... Electrons are electrochemically negatively charged particles that move random around the nucleus

Explanation:

Protons are positively charged, neutrons are neutral and they both are located in the nucleus whereas electrons are negatively charged and located outside the nucleus.

Explanation:

Atom is defined as the smallest unit of a matter.It consists of three subatomic particles: protons, neutrons, electrons.Protons and neutrons are located inside the nucleus. They are also known as nucleonsElectrons are located outside the nucleus.Protons carry a positive charge, electrons carry a negative charge, and neutrons carry no charge (neutral).

So from this, we conclude that the protons are positively charged, neutrons are neutral and they both are located in the nucleus whereas electrons are negatively charged and located outside the nucleus

The MSDS for benzene indicates that it is a clear liquid that has a substantial vapor pressure. It has a health rating of
2, a fire rating of 3, and a reactivity rating of 0. It is a cancer-causing agent.
Based on this information, which siatement about benzene is accurate?
Benzene readily reacts with moist air.
Benzene explodes if the container is shaken.
Benzene must be kept away from flames.
Benzene must be stored under high pressure.

Answers

Based on the provided information, the statement that is accurate about benzene is that it must be kept away from flames. This is because benzene has a high flammability rating of 3, which indicates that it can ignite and burn easily.

Additionally, the MSDS states that benzene has a substantial vapor pressure, which means it can easily evaporate into the air and form flammable mixtures with air.

The other statements are not accurate. Benzene does not readily react with moist air or explode if the container is shaken. It also does not need to be stored under high pressure. However, benzene is a cancer-causing agent, so it is important to handle it with care and follow proper safety precautions.

What is phase change?

The phase can be defined as the state of the matter. With the change in the temperature and the pressure values, the state of the matter, or the phase changes.

The hail has been the solid precipitation of the rain water. With the lowering of the temperature to the critical pressure, the water converts to ice.

The conversion of water to ice has been termed as freezing, Thus, hail is an example of freezing. Hence, option D is correct.

yo someone please help meee The density of silver is 10.5 g/cm3. What is the mass (in kilograms) of a cube of silver that measures 0.69 m on each side?

Answers

Mass=volume x density

Mass of the cube of silver is 3,449.34 kg

First find the volume of the cube in centimeters because the density is in centimeters:

0.69 * 100 = 69 centimeters

Volume = Side * Side * Side

= 0.69 x 0.69 x 0.69

= 328,509 cm³

The density of a material is calculated by the formula:

= Mass / Volume

As you have the density already and the volume, you can get the mass:

10.5 = Mass / 328,509

Mass = 10.5 * 328,509

= 3,449,344.50 grams

A kilogram is 1,000 grams so the mass in kg is:

= 3,449,344.50 / 1,000

= 3,449.3445 kilograms

If a gas has a mass of 468 grams and its density is 17 grams per liter, how much volume does it occupy?

Answers

Answer:

The answer is

27.53 Litres

Explanation:

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

[tex]volume = \frac{mass}{Density} [/tex]

From the question

mass = 468 g

Density = 17 g/L

Substitute the values into the above formula and solve

We have

[tex]volume = \frac{468}{17} \\ = 27.529411[/tex]

We have the final answer as

27.53 L

Why do atoms always contain the same number of electrons and protons?

Answers

Answer:

An electron is a negatively charged subatomic particle and a proton is a positively charged subatomic particle. Positive charge(s) attract negative charge(s) and vice versa. The proton and neutron stay together and attract one another to give the atom an overall charge of zero (neutral). Which is the charge of an atom. When there is an unequal number of protons and neutrons an ion is formed. If the number of protons are more than the electron, a positively charged ion called cation is formed. On the other hand, if the number of electrons are more than the protons a negatively charged ion called anion is formed.

Answer:

When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral. ... Chemically, we say that the atoms have formed bonds.
