Answer:
1. naoh + h₂o → na⁺ + oh⁻ + h₂o + heat
2. naoh + hcl → nacl + h₂o
explanation:
1. the dissolving of naoh in water is an exothermic reaction resulting a heat. it also causes the dissociation of naoh to its ions (na⁺ and oh⁻).
so, the balanced equation will be naoh + h₂o → na⁺ + oh⁻ + h₂o + heat.
2. the reaction between acid and base resulting salt and water. it is considered as a neutralization reaction.
the reaction between hcl and naoh will give sodium chloride and water and the balanced equation will be naoh + hcl → nacl + h₂o.

Answer:
Melamine is used for making tableware,cooking utensils, plates, plastic products etc.
Explanation:
Melamine is used to manufacture many products. How? Well melamine-formaldehyde resin, as it's full name, forms molecular structures that are molded, with heat, to take the shape of the items such as tableware.
After this chemical reaction takes place, the "left over" remains as plastic.
