It attempts to describe and account for the properties of molecules and atoms and their constituents—electrons, protons, neutrons, and other more esoteric particles such as quarks and gluons.
Answer:
Ethanol is produced
Explanation:
The production of ethanol indicates that ethanol fermentation is occurring, which is a type of anaerobic respiration.
Carbon dioxide is produced and glucose is consumed by both aerobic and anaerobic respiration, so this does not indicate which type of respiration is occurring. Oxygen is only consumed by aerobic respiration, so the consumption of oxygen would indicate that aerobic respiration is occurring.
First determine the molality of the solution. m = (w solute)/[(mm solute)(kg solvent)] -- mm means molar mass. So,
m = (14.7 g)/[(180 g/mol)(0.150 kg) =0.544 mol/kg = 0.544 m
Change in boiling point (∆t) = m x Kbp = (0.544 m)(0.512 °C/m) = 0.28°C
The solution will boil at 100.28°C at 1 atm.
the density if water is 1.00 g/ml and Kb= 0.512 C/m
Hi there!
Liquid and gas phase can both allow objects to pass through them, whereas solid phase does not.
Hope this helps!
