Heat from the Earth's core and radiation from the Sun is transferred to the surface of the Earth by conduction. Contact of the atmosphere with these warm surfaces transfers thermal energy, which then heats up the rest of the air through convection
Arrhenius equation is LaTeX: y=-15035x+41.45y = − 15035 x + 41.45. What is the activation energy for this reaction is described below.
Explanation:
When the rates are equal and the concentration of reactants and products are constant not equal. Other like activation energies and potential energies are not necessary for equilibrium.
The activation energies of the forward and reverse reactions ,the rates of the forward and reverse reactions are 25 minutes ago.
For a hypothetical reaction the linear Arrhenius equation is LaTeX: y=-15035x+41.45y = − 15035 x + 41.45
15kj/mol is the answer..
Answer: The new penny is not pure copper
Explanation:
Density 
is defined as a relation between the mass 
and the volume 
:
Now, we are told the density of pure copper is:
And we are given the mass and volume of the new penny, with which we can calculate its density:
As we can see the density of this penny is not equal to the density of pure copper, hence the new penny is not pure copper.
