How to solve a balanced equation

geniusboy [140]

Explanation:

To balance a chemical equation, there are so many approaches to solve the problem.

A balanced chemical equation is one that obeys the law of conservation of matter.

According to this law "matter is neither created nor destroyed by atoms are just rearranged in chemical reaction".

This implies implies that equal number of atoms must be on both sides of the equation.

There are two main approaches to balancing chemical equation;

Inspection
mathematical equation

We can inspect the equation and affix the proper coefficients to combining species.

Mathematically, we establish simple solvable algebraic equations to find the number of respective coefficients that will balance the equation:

For example:

H₂ + O₂ → H₂O

mathematically;

aH₂ + bO₂ → cH₂O

conserving:

H : 2a = 2c

O: 2b = c

let a = 1

c = 1

b = $\frac{1}{2}$

multiply by 2 to give;

a = 2, b = 1 , c= 2

2H₂ + O₂ → 2H₂O

Answer:

Question 1 :

• A compound is ionic if it is made up of a metal or a cation (+) and a non metal or anion (-)

Question 2 :

• While naming ionic compounds, follow the formula → "metal" + "non-metal ending with ide "

• i.e; Sodium Chloride:

${ \rm{Na {}^{ + } _{(aq)} + Cl {}^{ - } _{(aq)} \: \dashrightarrow \: NaCl _{(aq)}} \: \: \: \: \: \: \: \: } \\ { \rm{sodium + chloride \: \dashrightarrow \: sodium \: chloride}}$

Question 3 :

• The answer above that question is perfect.

Question 4 :

1 atom → Mono. But it is highly recommended to ignore it

2 atoms → DI

3 atoms → TRI

4 atoms → TETRA

5 atoms → PENTA ( such as pentaoxide )

7 atoms → HEPTA ( such as heptaoxide )

Question 5 and 6:

Are perfectly answered.
