Answer:80KM is distance. 30KM north is displacement.
Explanation:
Your balanced equation for this reaction is:
HCOOH (aq) + H2O (aq) → HCOO- (aq) + H3O+ (aq)
So from the reaction, we can see when formic acid dissolved in water so H3O+ ions will be formed.
and we can see that it is a balanced equation as:
we have H atoms = 4 on both sides of the reaction
and C atoms = 1 atom on both sides of the reaction
and O atoms = 3 atoms on both sides of the reaction
So it is our final balanced equation of the reaction.
White light is what the eye sees when wavelengths of all colours reach the eye.
It is a combination of Red, Blue and Green wavelengths of light, that is perceived as white.
Is there any more info lol
But from thinking I got A=DH^2*BC
