Question

1. How many grams of potassium chlorate are needed to make a saturated solution in 100 G of water at 90°C 2. How many grams of potassium chloride can be dissolved in 100.0g of water at 20°C 3 . 10.0G of KCl are dissolved in 100 G of water at 40°C. How many more grams should be added to the saturated solution 4. 85 g of calcium chloride is dissolved in 100 g of water at 20°C. Is the solution unsaturated, saturated, or supersaturated 5.

Definition Definition Substance that constitutes everything in the universe. Matter consists of atoms, which 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: solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
