Question

what is hit and trial method in chemical reaction ?​

Answer 1

Answer:

Hey there, hope I'll be able to help you upon this.

We use hit and trial method in balancing of a reaction in which we have to balance the number of atoms of each element on both sides of the reaction.

We do this by placing random numbers in front of reactors and products hoping that'd balance the atoms in the reaction.

Tho it seems complicated it's comparatively easy :)

For example,

I have a reaction to balance which is somewhat like this

MgO --> Mg + O2

I see there are 2 atoms of Oxygen on the RHS but only one on the left so I quickly place a 2 on front of MgO

2MgO --> Mg + O2

Another difficulty pops up as Mg is left unbalanced now.

So I add a 2 in front of Mg too.

2MgO --> 2Mg + O2

It's balanced now yay!

So this was the hit and trial method. :)

Answer 2

$\purple \bigstar$ In the hit and trial method of balancing chemical equations, experiments are carried out by using the least whole number coefficient to balance the chemical equation. Hence it is known as the hit and trial method. Count the number of times on both sides that an element occurs.
