The chemical equation of the reaction between Hydrogen and Oxygen is given below

Firdavs [7]

Answer:

1. a. The reactants are H₂ and O₂; The product is H₂O

b. The equation is not balanced because the number of atoms of the elements reacting is not equal to the number of atoms produced. 2 atoms of oxygen reacted but only one atom of oxygen is produced.

c. 2 H₂ + O₂ ---> 2 H₂O

2. a. The monotonic molecule is the sodium molecule, Na, since itnis made up of only one atom in its molecule.

The diatomic molecule is oxygen molecule, O₂, since it is made up of two atoms in its molecule.

b. The chemical compound present is sodium oxide, Na₂O

c. 4 Na + O₂ ---> 2 Na₂O

Explanation:

In a chemical reaction, the reactants are the elements or compounds which are converted to a new substance whichnis known as the product. The products are the new substances formed from the reactants.

In the given equation of reaction below;

H₂ + O₂ ---> H₂O

a. The reactants are H₂ and O₂; The product is H₂O

b. The equation is not balanced because the number of atoms of the elements reacting is not equal to the number of atoms produced. 2 atoms of oxygen reacted but only one atom of oxygen is produced.

c. 2 H₂ + O₂ ---> 2 H₂O

2. Given the reaction equation below:

Na + O₂ ---> Na₂O

a. The monotonic molecule is the sodium molecule, Na, since it is made up of only one atom in its molecule.

The diatomic molecule is oxygen molecule, O₂, since it is made up of two atoms in its molecule.

b. The chemical compound present is sodium oxide, Na₂O since itconsists of two chemically combined elements, sodium and oxygen.

c. 4 Na + O₂ ---> 2 Na₂O

100 points! Formation of an Ion

djyliett [7]

$\huge\underline\pink {Answer}$

If every oxygen ion is combined with an aluminium ion has a charge of -2,the charge of each aluminum ion would be -3.

Uncharged Aluminum atom must need to lose it's electrons,in order to form the bond with oxygen which has vacant orbitals

ion

atom that has a positive or negative charge because it lost or gained one or more electrons

chemical bond

the attractive force that holds atoms or ions together

ionic bond

a chemical bond in which one atom loses an electron and the other atom gains electrons to form ions

chemical formula

a combination of chemical symbols and numbers to represent a substance

covalent bond

bond formed by the sharing of electrons between atoms
