n² + h² ➡️ nh³

N₂ +  3H₂    →       2NH₃

Explanation:

Chemical equation:

N₂ +  H₂    →       NH₃

Balanced chemical equation:

N₂ +  3H₂    →       2NH₃

Step 1:

N₂ +  H₂    →       NH₃

left hand side:                       Right hand side

N =  2                                     N = 1

H = 2                                      H = 3

Step 2:

N₂ +  3H₂    →       NH₃

left hand side:                       Right hand side

N =  2                                     N = 1

H = 6                                      H = 3

Step 3:

N₂ +  3H₂    →       2NH₃

left hand side:                       Right hand side

N =  2                                     N = 2

H = 6                                      H = 6

hi,

the capital city of australia is canberra.

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
