Answer: potential.
Chemical energy is the energy provided by a chemical reaction.
Kinetic energy is the energy due to the speed.
Potential energy is the energy due to the position. For example, an object on the top of a mountain, has the possibility to perform work if it falls.
Electromagnetic energy. is propagated by waves: radio waves, infrared radiation, microwaves, etc.
Answer:
no it should not that place is historical and so they should make where u can visit but protect it as a historical landmark
Answer: Option (A) is the correct answer.
Explanation:
A covalent bond is formed when there occurs sharing of electrons between atoms.
For example, in hydrogen atom there is one electron in its orbit and in a chlorine atom there is 7 valence electron. So, in order to attain stability both hydrogen and chlorine share electrons when they come close to each other.
Whereas except hydrogen and chlorine rest of the given atoms will form ionic bond, that is, bond formed by transfer of electrons.
Thus, we can conclude that a pair of hydrogen and chlorine will form a covalent bond.
Hydrogen (gas) + Chlorine (liquid)
Answer:
See below
Explanation:
The equation shows Al / Cl = 2/3 or 3/2 Al = Cl
3/2(20) = 30 Cl atoms needed
The equation shows a one-to-one relationship between Al and AlCl3
produced so if you use 20 Al atoms you get 20 AlCl3 molecules
