Explanation:

A compound is defined as a substance formed due to chemical combination of two different elements which are present in a fixed ratio by mass.

A compound is a pure substance as it can be broken down into its constituent elements.

For example, MgCl_{2} is a pure substance and it can be broken down into magnesium and chlorine ions.

Thus, we can conclude that a pure substance that contains atoms of more than one element called compound.

An element is a pure substance that consists entirely of one pure substance. Compounds are a substance that is formed by two or more elements. Elements are composed of the same atomic atoms/molecules. This means that every particle in an element has the same number of protons in the nucleus.

a solution is an acid or base and it doesn't react with metal. is it pH more likely to be 4 or 9? explain your answer
coldgirl [10]
It is more likely 9. pH 4 is acidic and pH 9 is basic, and as the pH of a substance gets closer to 0 or 14, the substance becomes more corrosive or reactive. As 4 is closer to 0 than 9 is to 14, there is a much higher chance the solution has a pH of 9, because pH 4 is less neutral and therefore more corrosive/reactive than pH 9.

Calculate the number of molecules present in 0.5 mole of water​
Aleksandr-060686 [28]

Explanation:

Mole = 0.5 = n/NA

n = no. of molecule

NA = avogadro number = 6.023x 10^23

so

N/NA = 0.5

N = 0.5 x 6.023 x 10^23

N = 3.0115 x 10^23

A solid forms when the average energy of a substance's particles
Dahasolnce [82]
<span>Matter is composed of particles that have kinetic energy. Particles with greater kinetic energy tend form liquids or gases due to increased rates of activity of the particles. Particles with lower energy tend to form solids. So, a solid forms when the average energy of a substance's particles decreases.</span>
