Answer: Physical change
Explanation: Quite simple as the starfish opening a clam would mean the starfish is physically changing the clams look.
Answer:
About 7.89g/cm^3, I think.
Explanation:
Find the volume. Divide the mass by the volume.
Explanation:
The enthalpy of a reaction for a chemical change can be determined by
Using the formula ∆H = m x s x ∆T to solve.
∆H is the change in the enthalpy of the reaction.
where, m, the mass of our reactants,
s, the specific heat of our product,
and ∆T, the temperature change during the reaction,
Thus, we are ready to calculate the enthalpy of reaction.
Simply we can put in values into the formula ∆H = m x s x ∆T and multiply to solve.
Answer:
The retention factor would be high
Explanation:
The retention factor can be affected by the temperature, or affected by the composition of the solvent, when the FM are liquid.
Heptene is a derivative of the distillation of oil, it is a chemical compound that is made up of seven carbons, that is why it begins with the prefix hept.
