Answer:
All solutions are mixtures because it is two or more substances mixed together.
Explanation:
When is a mixture considered a solution.
Butyl group is CH3 CH2 Ch2 CH2 -
Methyl group is CH3 -
Pentane is CH3 CH2 CH2 CH2 CH3
4 - butyl - 2,3 dimethylpentane is
CH3 CH2 CH2 CH2 CH3

CH3
You can realize that there is a chain of 8 Cs (I bolded it).
The proper name must use the longest C chain; i.e octane.
In this case, there are 3 methyl groups attached to the 8 Cs chain, and they are at 2, 3 and 4 positions. Therefore, the name is:
2, 3, 4 trimethyl - octane
As per Le Chatelier's principle, if the equilibrium of a system is disturbed by changes in temperature, pressure, concentration etc then it will shift in a direction to undo the effect of the induced change.
The given reaction is:
CO + 3H2 ↔ CH4 + H2O
In this case, if the rate of the forward reaction is increased then more of the reactants get converted into products i.e. concentration of reactants decreases. In order to undo this change, the equilibrium will shift in a direction to produce more reactants i.e. to the left.
Ans: B) faster rate of forward reaction
When a liquid is frozen, the atoms in the liquid slow their movement due to lack of energy so the substance becomes hard.
