While doing a distillation, Farha heats the mixture too fast, and the temperature rises too quickly. If the mixture is composed

of two liquids, how will this likely affect the separation of the mixture?
A) The liquids will be separated in reverse order.
B) Both liquids will evaporate and escape into the air.
C) The liquid with the lower density will be collected before the liquid with the higher density.
D) Some liquid with the higher boiling point will be collected along with the liquid with the lower boiling point.

D as the two substances could have close boiling points, so if the temperature is not controlled well, both substances will evaporate.

Answer is: D) Some liquid with the higher boiling point will be collected along with the liquid with the lower boiling point.

For example if we have mixture of water and alcohol ethanol, we can separate water and ethanol with distillation (process of heating and cooling).

Ethanol and water have different boiling points (physical property), ethanol has boiling point (78.37°C) and water (100°C).

When the mixture is quickly heated, water contains a lot of ethanol.

The temperature should stay more or less constant.

In a 1.0-liter container there are, at equilibrium, 0.10 mole h2, 0.20 mole n2, and 0.40 mole nh3. what is the value of kc for t
bogdanovich [222]
The reaction involved here would be written as:

2N2 + 3H2 = 2NH3

The equilibrium constant of a reaction is the ratio of the concentrations of the products and the reactants when in equilibrium. The expression for the equilibrium constant of this reaction would be as follows:

Kc = [NH3]^2 / [N2]^2[H2]^3
Kc = 0.40^2 / (0.20)^2 (0.10)^3 
Kc = 4000

Through which conversion is energy released? adp to atp atp to adp nadp to nadph co2 and h2o to c6h12o6 and o2
aleksandrvk [35]
  • Energy transformation includes ATP and ADP. at the point when energy is delivered, the response will in general separate a bigger particle to a more modest structure.
  • For this situation, the bigger particle is ATP comprised of three phosphates bunches while ADP is just made out of two phosphate gatherings.
<h3>What is the energy source for the conversion of ADP and ATP?</h3>
  • The energy expected for the change of ADP into ATP is acquired from light during photosynthesis and from exothermic responses during cell breath in the two plants and creatures.
  • ADP is produced on hydrolysis of ATP and the energy released in the process is utilised to carry out various cellular processes.

How does temperature change during a chemical reaction
snow_tiger [21]

A change in temperature is a sign that a chemical reaction has occurred. This occurs in an endothermic reaction. An endothermic process is any process which requires or absorbs energy from its surroundings, usually in the form of heat. It may be a chemical process, such as dissolving ammonium nitrate in water, or simply the melting of ice cubes.

Hopefully im not too late :/
