Which of the following factors would reduce the yield of a reaction?
NikAS [45]

The products being more stable than the reactants is the factor which would reduce the yield of a reaction and is denoted as option B under standard conditions.

<h3>What is a Chemical reaction?</h3>

This is the process in which one or more substances which are referred to as reactants are converted into new substances which we call the products.

A chemical reaction involves atoms exhibiting different bond formation so as to ensure they acquire an octet configuration and promotes proper stability of the products.

When the products are more stable than the reactants it means it is unable to form other products thereby decreasing the yield which is why it was chosen as the most appropriate choice.

What are elements and how do they differ?
vodomira [7]

Answer:

Explanation:

Compound

A compound contains atoms of different elements chemically combined together in a fixed ratio.

Compounds contain different elements in a fixed ratio arranged in a defined manner through chemical bonds. They contain only one type of molecule. Elements that compose the compound are chemically combined.

A compound can be separated into simpler substances by chemical methods/reactions.

A huge, virtually limitless, number of chemical compounds can be created. Compounds are classified into molecular compounds, ionic compounds, intermetallic compounds and complexes.

A compound is represented using its chemical formula that represents the symbols of its constituent elements and the number of atoms of each element in one molecule of the compound

Element

An element is a pure chemical substance made of same type of atom.

Elements contain only one type of atom. Each atom has the same atomic number i.e., the same number of protons in their nucleus.

Elements cannot be broken down into simpler substances by chemical reactions.

There are about 117 elements that have been observed. Can be classified as metal, non-metal or metalloid.

An element is represented using symbols.
