Question

what is the chemical formula of the following
1. Calcium carbonate
2.Potassium nitrate

​

Answer 1

Answer:

1. CaCO3
2. KNO3

HOPE THIS IS HELPFUL

Answer 2

Chemical formula :-

1) Calcium carbonate

2) Potassium nitrate

______________________

Answer :-

1) Calcium = "Ca" Valency : +2 and Carbonate = "CO3" Valency : -2

So by heat and trial method you can get the answer :

Ca ⠀⠀⠀ CO3

⠀⠀⠀⠀⠀⠀⠀⠀⠀ = CaCO3 ✓

2 ⠀⠀⠀⠀⠀⠀2

So the answer is

$\boxed{ \tt{ \pink{CaCO3}}}$

_______________________

2) Potassium = "K" Valency : +1 and Nitrate = "NO3" Valency : -1

So again by heat and trial method you can get the answer :

K ⠀⠀⠀⠀⠀⠀NO3

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= KNO3 ✓

2 ⠀⠀⠀⠀⠀⠀⠀⠀2

So the answer is :

$\boxed{ \tt{ \pink{KNO3}}}$
