Answer:
2.89× 10²³ atom
Explanation:
Given data:
Number of atoms of Zn = ?
Number of moles of Zn = 0.48 mol
Solution:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ atom
0.48 mol × 6.022 × 10²³ atom / 1mol
2.89× 10²³ atom
I have no idea how about it lol I t
The answer to this question would be: electron
When atoms bind together, that mean they shared at least one electron. The electron is located on the outer side of the atoms so the electron from an atom can collide with other electrons from another atom. The protons and neutron can't make bind because it was in the middle of the atom and won't collide each other.
Answer:
I think it's b if not then sorry
Physical changes are changes affecting the form of a chemical substance, but not it`s chemical composition.
A physical change, changes the following:
-appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, and many others.
Answer:
C. density(the degree of compactness of a substance)
