After having performed a "collecting gas over water" experiment to determine the molar mass of zinc, you discover that not all of the zinc in the filtering flask reacted with the hydrochloric acid. How would this new observation affect your reported molar mass value? a) the calculated molar mass would be better than the true molar mass b) the calculated molar mass would be lower than the true molar mass c) the experimental results would not adversely be affected d) the calculated molar mass would be higher than the true molar mass
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.
