There are two types of fermentation aerobic and anaerobic. Aerobic are those that need oxygen to ferment while anaerobic are those who do not need oxygen. Products of fermentation are usually water, ethanol, lactic acid and carbon dioxide. Other products are acetone and butyric acid.
Answer:
The particles that make up a substance in its liquid state have <u>more </u>kinetic energy than those of the same substance in its solid-state.
For a solid to melt, energy must be <u>added to</u> the system.
For a liquid to freeze, energy must be <u>removed from</u> the system.
Well electrons are like electricity well it is partly if it went 3 sub levels the electrons would blow up some electricty<span />

Answer:
Explanation:
Molal freezing point depression constant of butanol Kf = 8.37⁰C /m
ΔTf = Kf x m , m is no of moles of solute per kg of solvent .
mol weight of butanol = 70 g
235.1 g of butanol = 235.1 / 70 = 3.3585 moles
3.3585 moles of butanol dissolved in 4.14 kg of water .
ΔTf = 8.37 x 3.3585 / 4.14
= 6.79⁰C
Depression in freezing point = 6.79
freezing point of solution = - 6.79⁰C .
