Copper oxide(solid) + Sulphuric Acid (aqueous)-> Copper Sulphate (aqueous)+ Water(liquid)

In equation form:

CuO +H2SO4 -> CuSO4 + H2O

The colour change you will see is black to blue as Copper oxide is usually found as a black powder. Upon the reaction with sulphuric acid it will change to a cyan blue.

If you heat the made solution of copper sulphate, the water will evaporate and you will be left with white anhydrous copper sulphate crystals.

Atoms whose atomic number are the same but whose mass numbers are different are called: alpha particles ions beta particles isot
Kaylis [27]
<h2>Atoms whose atomic number are the same but whose mass numbers are different are called : Isotopes </h2>

Explanation:

Isotopes

They are the   elements with same atomic number but different mass number .

for example : Protium , deuterium and tritium are isotopes of hydrogen .

                    : C-14 and C-12 are isotopes of oxygen .

                     : Cl-35.5 and Cl-37 are isotopes of chlorine

Alpha particles

They are helium nuclei with +2 unit charge and 4 a.m.u mass

They are represented as : He₂⁴.

Ions

The atom carrying charge is called as ion .

It can be of two types : Cation and anion

cation :atom with positive charge

Anion : atom with negative charge

Beta particles

They are actually particles with charge and mass of electron and is represented as :₀ e⁻¹

What happens when nitrogen fills its valence shell?
Sauron [17]
The right answer is D. three electrons are gained, creating N-3

Nitrogen has 5 electrons in it's valence shell and octet rule states that the valence shell must have 8 electrons. To satisfy that, Nitrogen gains 3 electrons that are negatively charged.Therefore, it gets a negative charge.

What is the difference between a proton, neutron, and electron?
jok3333 [9.3K]

Answer:

proton :

a particale or atom containing a postive charge

nuutron

a particale or atom that contains a negative charge

electron :

a particale or atom with a negative chrage.

Explanation:

proton:

a stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron, but of opposite sign.

nuetron:

a subatomic particle of about the same mass as a proton but without an electric charge, present in all atomic nuclei except those of ordinary hydrogen.

elcetron:

a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.
