Answer:
Explanation:
Mechanical energy = Gravitational potential energy + kinetic energy
Time Gravitational potential energy kinetic energy Total ME
0 4 0 4
2 2 2 4
4 0 4 4
6 2 2 4
8 4 0 4
and so on .....
We see that total mechanical energy is always 4 which is constant .
So gravitational and kinetic energy changes cyclically but total mechanical energy is constant .
The type of bond between the atoms in the carbon dioxide molecule is COVALENT BOND.
Covalent bond involves sharing of electrons between the atoms that are involved in the chemical reaction. The one carbon atom and the two oxygen atom that formed the carbon dioxide molecule share electrons in such a way that the outermost shell of each atom is made up of eight electrons.<span />
Answer: <span>The main interactions between molecules of hydrogen chloride are examples of
Dipole-Dipole Interactions.
Explanation: The bond between Hydrogen and Chlorine is
Polar Covalent Bond as the
electronegativity difference between these two elements is
0.96 which is greater than 0.4. Chlorine being more electronegative attracts the electrons from Hydrogen making the Hydrogen
partial positive and itself
partial negative. The two poles on HCl makes it a dipole. Now, one HCl (a dipole) interacts with another HCl (another Dipole) through their opposite charges and creates
Dipole-Dipole Interaction. The picture is as below, the
green dashed lines are interactions,
