A substance is an element if it consists of a single type of atom. A substance is a compound if it is made up of more than one element.

<h3>Elements and compounds</h3>

In chemistry, an element is defined as all pure substances consisting of the same atom. For example, magnesium and potassium metal are all elements because they consist of magnesium and potassium atoms only.

On the other hand, compounds are defined as substances consisting of 2 or more atoms of different elements. For example, sodium chloride consists of atoms of sodium and chlorine. Hence, it is considered to be a compound.

Is it possible to use subatomic particles as an energy source?
Alex17521 [72]

Yes, Is it possible to use subatomic particles as an energy source.

<h3>What are subatomic particles?</h3>

A subatomic particle is nothing but a particle which is smaller than an atom in size. Typically, an atom can be broken down into three subatomic particles, namely: protons, electrons, and neutrons.

Yes, Is it possible to use subatomic particles as an energy source.

There are instances when the protons and electrons in an atom's outermost shells are not strongly attracted to one another. It is possible to force these electrons out of their orbits.

They may move from one atom to another by exerting force. Electricity is made up of these moving electrons.

Genetic equilibrium is the state in which allele frequencies do<br> not change in a<br> Check it
Vikentia [17]

Answer:

Genetic equilibrium is the state in which allele frequencies do

not change in a generation over generation.

Explanation:

Genetic equilibrium can be described as a situation which arises when a certain allele or genotype remains constant for a species generation over generations. Genetic equilibrium can be maintained if no external factors like mutations affect the population of the species. The phenomenon of natural selection and evolution need to be stopped if a genetic equilibrium is to be maintained. Hardy-Weinberg theorem is the mathematical depiction of genetic equilibrium.

The enthalpy of vaporization of water is 2,257,000 J/kg. If I have a 1 kg sample, how much energy is needed to boil all of it
worty [1.4K]

Answer:

2257000 J

Explanation:

Applying,

Q = Cₓm.................. Equation 1

Where Q = amount of energy need to boil the water, Cₓ = Enthalpy of vaporization of water, m = mass of water.

From the question,

Given: Cₓ = 2257000 J/kg, m = 1 kg

Substitute these values into equation 1

Q = 2257000×1

Q = 2257000 J

Hence the energy needed to boil all of the water is 2257000 J
