A student analyzed an antacid tablet from a bottle of 50 tables purchased at a discount store for $1.00. The mass of the tablet was 1.470 g.After adding 25.00 mL of 0.7989 M HCl solution to the tablet, the student back-titrated the excess HCl with 3.55 mL of 1.017 M NaOHsolution. Calculate the number of moles of stomach acid neutralized by one Calculate the mass effectiveness of the tablet (mol H+/g). Calculate the cost effectiveness of one tablet ($/mol H+).
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.
