Question

1. what is a binary compound? binary compounds are compound made up of only two elements. 2. give two examples of binary compound found in the home.

Explanation:

Question 1

A binary compound is defined as a chemical compound that consists of exactly two different elements. For example, in a compound like \( \text{H}_2\text{O} \) (water), there are two elements: hydrogen (\( \text{H} \)) and oxygen (\( \text{O} \)). In \( \text{NaCl} \) (sodium chloride), the two elements are sodium (\( \text{Na} \)) and chlorine (\( \text{Cl} \)). The key is that the compound is composed of only two distinct chemical elements, and these elements can be a metal and a non - metal (as in ionic compounds) or two non - metals (as in covalent compounds).

1. Sodium Chloride (\( \text{NaCl} \)): It is commonly known as table salt, which is found in most kitchens. Sodium (\( \text{Na} \)) is a metal and chlorine (\( \text{Cl} \)) is a non - metal, and together they form this binary ionic compound.
2. Water (\( \text{H}_2\text{O} \)): It is present in our homes for drinking, cooking, etc. It is a binary covalent compound made up of hydrogen (\( \text{H} \)) and oxygen (\( \text{O} \)) elements. Other possible examples could be carbon dioxide (\( \text{CO}_2 \)) (found in carbonated drinks, though it's a gas at standard conditions but still present in homes), or hydrogen peroxide (\( \text{H}_2\text{O}_2 \)) (used as a disinfectant in some households).

Answer:

A binary compound is a chemical compound composed of exactly two different elements.
