a student obtains a sample of a sand/salt mixture in a test tube. home weighs the test tube with the sample and finds the mass to be 20.70 grams. He pours half of the mixture into a beaker and weighs the test tube and finds the mass to be 15.50 grams. how much of the sand salt mixture is in the beaker
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.
