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

If an ionic compound has a 2- charge how does that affect the total number of electrons in a Lewis structure
givi [52]

In the situation where an ion has a charge of -2, the Lewis structure is affected because it must add two additional electrons.

The Lewis structure is a term to refer to the graphical representation that shows the pairs of electrons in dashes or points of bonds between:

  • The atoms of a molecule
  • The lone electron pairs that may exist

Additionally, the charge of an ionic compound is calculated using the difference in electrical charge between the electrons. On the other hand, an ion is formed by adding or removing electrons, so the magnitude of the resulting charge depends on the number of electrons added or removed.

According to the above, if an ionic compound has a -2 charge, the Lewis structure must add two electrons.

Which process contributes to the formation of tornados?
DIA [1.3K]

Answer:

Warm air rises, resulting in a decrease air pressure.

Explanation:

Tornado is the rapid and violent rotation of column of air which move from the thunderstorm to the ground.

It is formed when there is collision between warm and cold air. The cold air which is more sense than the warm air is pushed over the warm air which result in thunderstorms. The warm air then rises which result in decrease air pressure causing an updraft. The updraft then begin to rotate as there are variations in wind speeds and directions.
