Explanation:
As all the mass of other molecules are given and we have to find the mass of hydrogen so total subtracted by carbon and oxygen.
Answer:
Law of cross-cutting relationships
Explanation:
This interpretation is based on the law of cross - cutting relationships.
This law states that "faults and fractures that cuts through a rock are younger than the rocks they cut through".
- In a sequence of strata, the strata that are not cut through by these features are younger than the cross -cutting features.
- The igneous intrusion is younger since it cuts through the rock layers.

Answer;
= 0.054 kg or 54 g
Explanation;
Using the equation; Q = mcΔT where Q is the quantity of heat transferred, m is the mass, c is specific heat of the substance, ΔT is delta T, the change in temperature.
ΔT = 75 - 20 = 55 C.
Solve the equation for m
m = Q/ cΔT
Mass = 12500 / (55 × 4200)
= 0.054 kg or 54 g
