Answer: Substance B has stronger bonds, and it takes more energy to undergo a phase change.
Explanation:
Substances with higher boilings have stronger intermolecular forces, and thus require more energy for phase changes to occur.
The upper surface of the zone of saturation is called the water table
Answer:
radiation
Explanation:

Answer:
the rate of a reaction is measured by how fast a REACTANT is used up or how fast a PRODUCT is formed
<span>Looking at the equation, 2 moles of FeO are produced from every 2 moles of CuFeS2. That means 8 moles of CuFeS2 will produce 8 moles of FeO (assuming there is sufficient oxygen, O2, in the reaction)</span>
