Ions are atoms with a charge other than zero. In a neutral atom, the number of protons (positively charged particles) in the nucleus equals the number of electrons orbiting the nucleus.
Atoms can gain or lose electrons (not protons) resulting in a net charge other than zero. Atoms which lose electrons (usually metals) become positively charges, and atoms which gain electrons (usually nonmetals) become negatively charged.

Answer:

please mark my answer brainliest

Explanation:

nice question...

ok solution goes right the way through...

in temp 193°C the volume of gas was 892ml

so for...144°C the volume of gas will be 892/193x144=665.533 or 665.534...(rounded off)...or 665°...(approx)....so got ur answer...

I hope it helps....

please comment if you have any further questions...i will be solving it for u...

Metallic bonds are responsible for many properties of metals such as conductivity true or false?.

Alex17521 [72]

It is true that metallic bonds are responsible for many properties of metals such as conductivity.

Metallic bond is a type of chemical bond.

Metallic bond is formed between electrons and positively charged metal ions.

Substances with metallic bond conduct an electric current in liquid and solid state, because they have mobile electrons.

Most metals (for example sodium, calcium, iron, silver) have strong metallic bond, because strong electrostatic attractive force between valence electrons (metals usually have low ionization energy and lose electrons easy) and positively charged metal ions.

Metallic bond increace electrical and thermal conductivity.

Kobotan [32]

First convert the 2 temperatures to degrees K:
4 + 273 ---> 277 and 22---> 295

So using Charles' Law

V1 / T1 = V2 / T2
0.50 / 295 = V2 / 277

solving for V2 gives a volume of 0.469 L to nearest milliliter
