i may be wrong but Use the normal boiling points: propane, C3H8, –42.1˚C; butane, C4H10, –0.5˚C; pentane, C5H12, 36.1˚C; hexane, C6H14, 68.7˚C; heptane, C7H16, 98.4˚C; to estimate the normal boiling point of octane, C8H18.

Answer:

C₄H₁₀ > C₃H₈

Explanation:

Propane (C₃H₈) is symmetrical and non-polar, so the only inter-molecular forces are London dispersion forces.

Butane (C₄H₁₀) is symmetrical and non-polar, so the only inter-molecular forces are also London dispersion forces.

The only difference is the size. Butane has more atoms, more surface area, and therefore more inter-molecular forces. So it has a higher boiling point.

C₄H₁₀ > C₃H₈

Periodic table the first row of elements fits in the period blank after the element blank the second row of elements fits in per

Bezzdna [24]

Answer:

The first row fits in period 2

The second row fits in period 3

Explanation:

Elements arranged vertically in the periodic table in groups that share similar chemical properties.

Elements are also organized horizontally in rows or periods

The length of each period is determined by the number of electrons that can occupy the sublevels being filled in that period.

A house is built with a granite countertop. The heat capacity of the countertop is 158.5 kJ/°C. A hot pan of water is placed on

Svetlanka [38]

The temperature of the countertop changes by 0.032 °C

The quantity of heat transferred to the countertop is given by

Q = CΔT where Q = quantity of heat transferred to the countertop = 5000 J = 5 kJ, C = heat capacity of the countertop = 158.5 kJ/°C and ΔT = temperature change of the countertop.

Since we require the temperature change of the countertop, we make ΔT subject of the formula.

So, ΔT = Q/C

So, substituting the values of the variables into the equation, we have

ΔT = Q/C

ΔT = 5 kJ/158.5 kJ/°C

ΔT = 0.032 °C

So, the temperature of the countertop changes by 0.032 °C
