V(NaOH)*M(NaOH)=V(HCOOH)M(HCOOH)
35.43ml*0.1150m=20.00ml*M(HCOOH)
M(HCOOH)=0.2037m
Answer:
0.96 g/cm3, and it will float!
Explanation:
I've explained how to do this before (remember me? lol), but ig I'll do it again..
By looking at the graph you can see that Object C has a mass of ~24 grams and a volume of ~25 cm3
Density = Mass/Volume -> 24 grams/25 cm3 = 0.96 g/cm3
Density of water is 1 g/cm3
Object C is less dense than water and therefore will float (just barely, though)
:)
Answer:
A) One that occurs on its own
As acid rain is a mixture of pollutants and gasses. As rusting is a chemical reaction between oxygen and other gasses in the air alongside a material and a liquid. I would say they are both similar and that acid rain would speed the process of rusting/aid the process.
