Concept explainers

States of Matter

The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).

Chemical Reactions and Equations

When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.

Chlorophyll molecules are responsible for the green pigmentation of plants. Differing chemically isolated molecular chlorophyll compounds are named as "Chlorophyll X" (where "X" is a variable denoting the actual molecular fragments which are represented by the labels R2, R3, R7, Rg, R17). Suppose one molecule of ChlorophyllX contains 5 oxygen atoms, and Chlorophyll X is 13.14 % oxygen by weight. Using only this information and the atomic mass of oxygen, determine the molecular mass of Chlorophyll X. The Chlorophyll X molecule contains one magnesium atom. What mass of magnesium is found in 7.11 g of Chlorophyll X compound?
