what do you mean by cuso4 and chemical raction a molecule is the smallest particle of an element or a compond that can exist by itseff what is the meaning of that and last question from my is what do you man by atomicity and what is the meaning of the atomicity my question is hydrogen + oxygen---- water how it will be equation
Answers
1. CuSO4 is a chemical compound which is formed by the combination of copper metal and sulphuric acid. It is a salt which dissociates completely in water.
2. The chemical reaction is a reaction in which two or more chemicals combines to form a new product.
For example, when iron reacts with water and oxygen, it forms rust.
3. Atom is the smallest particle of an atom or compound means atom is the building block of elements and compounds. When two or more identical atoms combines they form elements whereas when two or more different atoms combines they form a compound.
4. Atomicity is the total number of atoms present in a given element or compound.
For example, the atomicity of the following compound is as follow:
He = 1
H2 = 2
P4 = 4
S8 = 8
5. The equation for the reaction of oxygen and hydrogen to form water is as follow:-
2H2+O2 → 2H2O.
