Explanation:
density = mass/volume
Acetone has density 0.784 g/ml
volume = mass/ density
Volume = 8.00/0.784
= 10.204 ml
The volume of 8.00g of acetone is 10.204 ml.
Im not sure but I did this a long time ago I think its 5.00 mols
Answer:
B. They bond identical atoms together
Explanation:
Metallic Bond: This is the bond that exists among the atoms of the metal. This is a type of electrostatic attraction between conduction electrons of metallic atom and their positively charged metal ions.
<em>(figure attached)</em>
Example:
Copper is a metallic element and its atoms consist of metallic bond among their selves.
Options A, B, D are not correct as all states for a kind of ionic bond formation.
Ionic bond:
It form by the complete transfer of electron from one atom to other
It is formed among two atoms of different electronegativities.
Also metals are electro-positive and non -metals are electro-negative so they form ionic bond.
Example is NaCl where sodium is a metal and Chloride is non-metal and they from ionic bond.
Element: is a pure substance with one type of atom, and what makes an element unique is its atomic/proton number
isotopes: is two or more species of atoms of a chemical element with the same atomic/proton number.(meaning in I should job has the same element but different neutrons)
ions: is a atom that has lost or gained electrons
Hopefully i could help(this was all from my notes so it’s a bit more simplified!!
