Answer:

Increases

Explanation:

As the number of carbons in the hydrocarbon increases, the boiling point of increases and volatility reduces.

The increasing number of carbon atoms increases the molecular mass and this will eventually lead to a higher boiling point.

With increasing chain length, hydrocarbons tends towards liquid and solid phases.
This increase leads to a greater intermolecular interaction in the compound.
Intermolecular forces determines the boiling point of hydrocarbons.
This is why gasoline is easily combusted compared to lubricant oil.

( HELP) The following system is at equilibrium. In which direction (right or left) will the equilibrium position shift with the

Alex Ar [27]

a) right

b) left

c) left

d) right

e) right

f) no effect

d) left

Explanation:

We have the following chemical reaction:

3 NO (g) ⇔ N₂O (g) + NO₂ (g) + 154.9 kJ

a) right, because by lowering the temperature you remove the heat generated by the reaction, and the reaction is able to generate more heat with the reaction proceeding from left to right.

b) left, because by increasing the temperature you add heat to the reaction and by doing so the reaction from right to left will be promoted.

c) left, increasing the concentration of N₂O the equilibrium will shift to left in order to consume the N₂O added.

d) right, increasing the concentration of NO the equilibrium will shift to right in order to consume the NO added.

e) right, decreasing the concentration of N₂O the equilibrium will shift to right in order to produce the removed N₂O.

f) no effect, adding a catalyst will not shift the equilibrium position, it will only modify the time in which the equilibrium is achieved and the energy required to achieve the equilibrium state.

g) left, by increasing the volume the equilibrium will shift to the part where more moles are produced (there are 3 moles on left side while in the right side there are 2 moles).

Identify the source of the electrons that travel down the electron transport chain. explain why oxygen is the final electron acc

satela [25.4K]

1) The electrons that travel down the electron transport chain come from the NADH and FADH2 molecules produced in the three previous stages of cellular respiration : glycolysis, pyruvate oxidation, and the <span>citric acid cycle.

</span>2) At the end of the electron transport chain is the Oxygen that will accept electrons and picks up protons to form water.
If the oxygen molecule is not there the electron transport chain will stop running, and ATP will no longer be produced.
