A student had only 12 M HCl solution, but needed 500. mL of a 3.5 M HCl solution. How would the student make the solution they needed? You need to both do a calculation and then explain in detail what you would do in the lab to make the solution. 45.80 mL of a 0.372 M H3PO4 solution were used to titrate 50.00 mL of a NaOH solution. Determine the molar concentration of the sodium hydroxide solution.
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.
