Sodium bicarbonate is commonly used to absorb odor. It's solubility is 9.6 g/100g H2O at 30 degrees C and 16g/ 100g H2O at 60 degrees Celsius, 9.2 g of baking soda are added to 46g of water. A) Is the resulting mixture homogeneous at 60 degrees C? If not, how many grams of baking soda are undissolved? B) The mixture is cooled to 30 degrees C. How many more grams of water are needed to make a saturated 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.
