Answer: a. Synthesis
Explanation:
a. Synthesis reaction is a chemical reaction in which two reactants are combining to form one product.
Example:
Thus magnesium in its elemental form is combining with oxygen to form magnesium oxide.
b. Double displacement reaction is one in which exchange of ions take place.
Example:
c. Decomposition is a type of chemical reaction in which one reactant gives two or more than two products.
Example:
The statement that describes a chemical reaction is the statement c. reactants form products when atoms are rearranged.<span> The atoms of the reactants are arranged is a specific position and number forming a determined compound. In a chemical reaction, the products are different compounds than the reactants, so the atoms have to rearrange to form these new compounds (the products).</span><span />
- The features which gives the definition of neutral atom is : the numbers of electrons is equal to number of protons
- Atoms can be regarded as neutral atom when they has same number of protons and the same numbers of electrons. Even after formation of the ion, there will still be the same number of protons.
- Example of this is sodium atom, which has 11 protons as well as 11 electrons
Therefore, number of electrons will be the same as the number of protons as regards neutral atom

Answer:
Explanation:
Spectator ions are defined as the ions which does not get involved in a chemical equation or they are ions which are found on both the sides of the chemical reaction present in ionic form.
The balanced chemical equation will be:

The total ionic chemical equation will be:

The ions which are present on both the sides of the equation are iodide ions and hence are not involved in net ionic equation.
