Answer:
D: Electromagnetic
Explanation:
Chemical energy is the energy in chemical bonds which is a type of potential energy, eliminating both B and C. While kinetic energy is the energy of motion, photons are a wave/ particle so thinking it would have kinetic energy wouldn't be your fault but light is on the electromagnetic spectrum making D the most likely answer.
Answer: 
, product favoured
Explanation:
Complete ionic equation : In complete ionic equation, all the substance that are strong electrolyte and present in an aqueous are represented in the form of ions.
Net ionic equation : In the net ionic equations, we do not include the spectator ions in the equations.
When hydrochloric acid react with potassium cyanide, then it gives potassium chloride and hydrocyanic acid as products.
The complete ionic equation will be:
The net ionic equation will not contain spectator ions which are 
and 
:
The reaction is product favoured.
When you get injured or hurt it affects the nervous system and let’s it react by the severity.
A compound is composed of a cation that is considered as the positively charged ion and an anion that is considered on the other hand as the negatively charged ion. In this case, when a compound is formed, an exchange of numbers reflected on the subscript takes place. The compound formed thus is X2Y
