Answer:
The oxidation number of C (carbon) is +4
Explanation:
The mesosphere is the coldest of the atmospheric layers. In fact it is colder than the Polar regions of the Earth cold enough to freeze water vapor into ice clouds. As you increase in altitude, temperature decreases The thermosphere is the layer to which this pattern does not apply.

Europe.
Asia.
North America.
South America.
Australia (or Oceania) THE ONLY CONTINENT WITHOUT GLACIERS!!
Antarctica.
<span>Heat capacity of an object, is the amount of heat energy or thermal energy (unit: Joule) needed to raise the temperature of the object by 1 degree celsius. Unit of heat capacity is J/°C
Larger object will surely need larger amount of thermal energy to raise its temperature. If you compare 1 litre of water with 0.5 litre of water, the 1L water will have two times the heat capacity.
It will be more useful to compare specific heat capacity, because then it is the amount of heat energy or thermal energy (unit: Joule) needed to raise the temperature of 1 unit mass of the object by 1 degree celsius. You can then compare between 1 unit mass of water and 1 unit mass of iron.
Water has higher specific heat capacity than iron, meaning that you need more energy to heat up 1kg of water, then to heat up 1kg of iron.
The unit will then be J/(kg °C) or J/(g °C).

Answer:- 
atoms of Cu are equals to 4.45 moles.
Solution:- It is a atoms to moles unit conversion for which we divide the given number of atoms by Avogadro number.
We have been given with atoms and asked to convert them to moles.
The set up for this unit conversion problem would be as:
= 4.45 moles
So, there would be 4.45 moles of Cu in atoms of Cu.
