Answer:
Number of mole = 13.155moles
Explanation:
One mole of a substance is equal to 6.022 * 10^23 units of that substance.
Mole of a substance can be defined according to chemistry as the mass of substance containing the same number of fundamental units
Using the formula for mole
n = m/Mm
n = number of mole
m = number of mass
Mm = number of molar mass
We are provided with some information
Given: mass of carbon to be 158g
Molar mass of C = 12.0107g/mol
Using the formula
n = m/Mm
n = 158 / 12.0107
n = 13.155 moles
A . Electrons are found in the nucleus of an atom

Answer:
•landslide
Explanation:
Landslides are exceptionally destructive. Homes may be destroyed as hillsides collapse. Landslides can even bury entire villages. Landslides may create lakes when the rocky material dams a stream.
Answer:
electrons
Explanation:
The photoelectric effect occurs when electrons are emitted from metal when the metal is struck by light of certain frequencies.
Some of the applications of this effect include photomultipliers (which are a key component in spectroscopy instruments) and night vision devices.
The melting point of the solid form of water, which is ice, is 0°C. When we convert both temperatures to kelvin by adding 273 to each we get the melting point of copper as 1357K and that of ice is 273K. Then, dividing the melting point of copper by the melting point of ice, both in absolute temperature scale. The answer would be 4.97. Thus, the energy of molecules of copper is approximately {five} times compared to that of water
