<u>Ans: A) HCl</u>

Neutralization reaction is one where an acid reacts with a base to form salt and water.

The given reaction is;

HCl + NaOH → NaCl + H2O

In general, an acid is the species which loses a proton i.e. H+ ion. Whereas base accepts a proton. Therefore the molecule where the proton count or the number of hydrogens decreases as the reaction proceeds can be identified as an acid.

Here, as the reaction progresses, HCl loses its hydrogen hence HCl is an acid i.e. hydrochloric acid.

NaOH, sodium hydroxide is a base

NaCl, sodium chloride is a salt.

In order for a chemical reaction to take place, what MUST ALWAYS occur?
Mumz [18]

Answer:

A chemical reaction is a process that leads to the transformation of one set of chemical substances to another.

Classically, chemical reactions encompass changes that only involve the positions of electrons in the forming and breaking of chemical bonds between atoms, with no change to the nuclei (no change to the elements present), and can often be described by a chemical equation.

Calcium forms ions with a charge of +2. Iodine forms ions with a charge of -1. Which of the following would represent an ionic c
astra-53 [7]

 The   formula that would represent an ionic  compound  that is composed of calcium and iodide ions  is   CaI2

 Explanation

Ionic compound  CaI₂ is formed  when Calcium form cation ( <em>a positively charged ion</em>) by losing 2 electrons while two iodine atoms form  anion ( <em>a negatively charged ion</em>)  by  gaining one electron each.

When writing down   formula of ionic compound, the formula  of cation  is written  first followed by anion  formula. therefore  Ca is written  first  followed by I.

The numeric subscript 2 after I(iodine) indicate that 2 atoms of iodine are involved  in bonding.
