Answer:
activation energy, in chemistry, the minimum amount of energy that is required to activate atoms or molecules to a condition in which they can undergo chemical transformation or physical transport. In transition-state theory, the activation energy is the difference in energy content between atoms or molecules in an activated or transition-state configuration and the corresponding atoms and molecules in their initial configuration. The activation energy is usually represented by the symbol Ea in mathematical expressions for such quantities as the reaction rate constant, k = Aexp(−Ea/RT), and the diffusion coefficient, D = Doexp(−Ea/RT).
this is just 60 divided by 15, which is 4
so your answer is 4A :)
Answer- A
Explanation- Because you have to look at the symbols and remember which symbol goes with each chemical, if you don't then you could get confused.
A. Atoms of chlorine (Cl)
Explanation:
The atoms of chlorine are held together by non-polar covalent bonds.
- Covalent bonds are formed between two or more atoms having zero or very small electronegativity difference.
- For homonuclear molecules where the two bonding atom are of the same kind, the electronegativity difference is zero.
- This covalent bond type is called non-polar covalent bond.
- In this bond type, there is equal sharing of the electron pair between the atoms and there is no electrostatic charge on the molecule.
