Answer:
A metal and a non-metal
Explanation:
Ionic bonds are formed between two or more atoms by the transfer of one or more electrons between atoms. Electron transfer produces negative ions called anions and positive ions called cations.
Where are the answer choices?
When all coefficients are multiplied by a single factor, The following actions are allowed while balancing a chemical equation: adding coefficients in front of reactant and product formulations.
<h3>How can chemical equations maintain balance?</h3>
Equal numbers and types of each atom appear on both sides of balanced chemical equations . Coefficients in a balanced equation must be the simplest whole number ratio. Chemical processes always retain mass.
<h3>What is a simple chemical equation?</h3>
A chemical equation is a symbol- and formula-based symbolic representation of a chemical reaction, with the reactant entities supplied on the left side and the product entities given on the right.

Answer:
It is a proposed explanation for a phenomenon.
Answer:
The best reagents that are used for the conversion of ethylbenzene to (2-bromoethyl)benzene is shown in the first diagram attached.
Explanation:
Concepts and reason
The concept used to solve this problem is by using the given reagents, possible products will be formed in each step and then label it exactly in the given boxes in order to form the exact product.
Here, the starting reactant is ethyl benzene and the final product is (2-bromoethyl)benzene.
Fundamentals
Bromine molecule is used for bromination of alkene. Trans addition takes place.
Addition of HBr to the double bond forms an alkyl bromide.
Potassium tertiary butoxide is a sterically hindered base.
Bromination of alkane in the presence of sunlight gives radical substitution.
NBS (N-bromosuccinimide) is used for the allylic bromination.
The reaction is as shown in the second attachment(pictures 2,3 and 4).
