H2A (aq) +2B(OH) (aq) --> 2H2O (l) + B2A (aq) In the above reaction, A has a molar mass of 35.453 g/mol and B has a molar mass of 22.99 g/mol. (Note the sig figs I used for the molar masses. You will want to use at least that many sig figs from the periodic table to get your complete compound molar mass.) I prepared a 10.00 mL solution H2A using 10.00 g of H2A and made 10.00 mL solution of the base using 15.00 g of BOH. Assuming the solid displaces a minimal amount of volume, what is the final concentration of B2A? Do not include units and make sure you use the correct number of sig figs.
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.
