Answer:
Newton's 2nd Law (Option B)
Explanation:
Answer:True
Explanation:
A ideal solution is a solution which obeys Raoults law on almost every concentration and temperature range.
Ideal solutions are formed by mixing those solute and solvent which has identical molecular properties.
Lets take A be the solute and B be the solvent so to form a ideal solution from these components the solute-solute(A-A) molecular interaction and solvent -solvent (B-B) molecular interactions must be identical with the solute solvent interaction(A-B).
The solute-solute molecular interaction ,solute-solvent molecular interaction and solvent-solvent molecular interaction must be equal in order to form a ideal solution.
The enthalpy of mixing and volume of mixing of ideal solution is zero.
enthalpy of mixing is the amount of energy released on mixing a solute and solvent and in case of ideal solutions it is zero.
Volume of mixing is change in volume on mixing a solute and solvent.

<span>The independent variable is the one that does not change depending on other variables - so here it would be the presence or the absence of caffeine - this is dependent on Tina's actions, but not on other variables in the experiment. The dependent variable is the heart rate - it is assumed to depend on the presence or absence of caffeine. A hypothesis could be that "Caffeine causes an increase of heart rate in earthworms" - and this hypothesis is what the experiment is testing.</span>
Answer:
96.3%
Explanation:
Data obtained from the question include:
Theoretical yield = 54g
Actual yield = 52g
Percentage yield =..?
The percentage yield can be obtain as follow:
Percentage yield = Actual yield /Theoretical yield x 100
Percentage yield = 52/54 x 100
Percentage yield = 96.3%
Therefore, the percentage yield of the reaction is 96.3%
