AATT You are a researcher in a geochemistry laboratory. A colleague brought to you a new mineral that you have never seen before. You need to identify all of the elements and their quantities in this mineral. You turn the mineral into a powder and put the mineral into multiple scientific machines to determine what it is made of. Your sample contained the following elements and amounts. • 160 grams of oxygen . 120 grams of silicon • 80 grams of aluminum ● 16 grams of magnesium . 32 grams of calcium. . 4 grams of uranium. Determine the mass percent of the different components in your soil sample. 29. Oxygen 30. Silicon 31. Aluminum 32. Magnesium 33. Calcium 34. Uranium
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.
