Answer:
The desert was one covered by ocean water.
Explanation:
I believe the answer is A, if they have a stronger connection lower the vapor pressure so higher the boiling point
Your answer is B, conservation of mass
Recall that percent yield is given by: %Yeild = actual yeild/theoretical yeild x100
During experiments, there are errors made:
• uncertainty in measurements
• losses of reactants and products
• impurity in reactants
• losses during separation (e.g. filtration or purification)
• Some side reactions might also happen.
Among the given options, only conservation of mass does not contribute to a lower actual yield compared to the theoretical yield.
generally bacteria reproduce by binary fission
