An experiment is performed using 7 liquids; Methanol, Ethanol, Propanol, Butanol, Water, Pentane and Acetone.

1 answer:

7 0

A). The weaker the IMF the lower the evaporation rates of each liquid. So Pentane had the weakest IMF and Butanol has the strongest.

b).They all evaporate at different rates because of their differences in their bonds. Not all liquids are the same and they will all most likely evaporate at different times

Answer:

Option D. Al is above H on the activity series.

Explanation:

The equation for the reaction is given below:

2Al + 6HBr —> 2AlBr₃ + 3H₂

The activity series gives us a background understanding of the reactivity of elements i.e how elements displace other elements when present in solution.

From the activity series of metals, we understood that metal higher in the series will displace those lower in the series.

Considering the equation given above, Al is higher than H in the activity series. Thus, the reaction will proceed as illustrated by the equation.

Therefore, we can conclude that the reaction will only occur if Al is higher than H in the activity series.

What does a chemical bond results from a rearrangement of?

Dmitriy789 [7]

Atoms

Explanation:

Chemical bonds results from the rearrangement of atoms in a chemical species.

It deals with the various attractive forces joining chemical species togethe.

When atoms are re-arranged, they form chemical bonds that leads to production of new compounds.
This is made possible by the exchange or sharing of electrons.
The driving force for most interatomic bonding is the tendency to have completely filled outer energy levels like the noble gases.
When atoms are re-arranged in compounds they lead to the production of chemical bonds.
