<em>From the above options, the best </em><em>Thermal insulator </em><em>will be a </em><em>Plastic cup.</em>

Option (b);

<u>Explanation</u>

Thermal insulators resist to conduct energy or reduction of heat transfer when objects come across in contact with radiation or higher heat object. To conduct energy we need metal or those materials which contain free electrons in it to move from one metal to another.

Plastic doesn't have metallic character so it will resist the heat up to some threshold. Mostly this material is used in separating two current-conducting material. There are many other examples of thermal insulator such as Rubber, fabrics, paper, wood, wool.

NH3 + HCI —&gt; NH4CI synthesis O decomposition O single replacement O double replacement​
wlad13 [49]

Answer:

synthesis

Explanation:

The reaction given is a synthesis reaction or combination reaction.

Given equation:

                        NH₃  +  HCl   →   NH₄Cl

In a synthesis reaction, a single product is formed from two or more reactants

                          A + B →  C

The formation of compounds from the union of constituent elements also falls into this category.

So the given reaction is a synthesis reaction.

In a decomposition reaction two or more products are formed from a single reactant

In a single replacement reaction, one substance replaces another.

In double replacement reactions partners in a chemical specie are exchanged.

Therefore the given reaction is a synthesis reaction
