Answer:
True.
Explanation:
this is because undisturbed sedimentary rocks forms in layers.
Answer:
This is a physical change.
Explanation:
As long as the identity of the substance has not changed, and the element is present before and after, it is a physical change! (Ex: ice melting)
Solid lead nitrate in water gives lead oxide and nitric acid
Pb(NO3)2 + H2O ---> PbO + 2 HNO3
Answer:
c2h4o2
Explanation:
I am using my cell. This could take a bit
The Empical formula has a mass of
C 12
2H 2
O 16
total = 30
The molecular mass is given as 60 which is 2 times the empirical mass. Therefore multiply each element by 2 in the empirical formula.
You get C2H4O2
Answer:
Nitrate NO3
