Answer:
should be appendix, I can't see any image tho.
Answer:
I^- or Cl^-
Explanation:
A nucleophile is any reagent that donates an unshared pair of electrons to form a new covalent bond. Nucleophiles are mostly bases also. Nucleophilicity is a kinetic property, it refers to the rate at which a nucleophile replaces a leaving group from an alkyl halide.
Looking at the options, Cl^- and I^- are the best nucleophiles among the options provided in the question.
Answer:
energy can neither be created nor destroyed but can be transfered from one form to the other
Explanation:
<u>Answer:</u> The given chemical reaction can be classified as synthesis and exothermic.
<u>Explanation:</u>
A synthesis reaction is defined as the reaction where two small chemical species combine in their elemental state to form a single large chemical species.
Exothermic reactions are defined as the reactions in which heat is released by the reaction. The heat is written on the product side of the reaction.
For the given chemical reaction:
![Mg(s)+O_2(g)\rightarrow MgO(s)+\text{heat}](https://tex.z-dn.net/?f=Mg%28s%29%2BO_2%28g%29%5Crightarrow%20MgO%28s%29%2B%5Ctext%7Bheat%7D)
The above chemical reaction is a type of synthesis and exothermic as two substances in their elemental state are combining. Also, heat is getting released in the reaction.
Hence, the given chemical reaction can be classified as synthesis and exothermic.
