Write a balanced formula equation for each of the following. Please answer parts (a) through (h) (a) Titanium metal reatcs with selenium to produce crystals of titanium(III) selenide. (b) Phosphoric acid is neutralized with barium hydroxide to produce a precipitate of barium phosphate in water. (c) Nitrogen gas reacts with lead(II) oxide powder to yield lead(II) nitride and oxygen gas. (d) Xenon hexafluoride crystals react with water to produce xenon trioxide powder and hydrofluoric acid. (e) Aluminum carbide is reacted with water in the synthesis of methane gas. Aluminum hydroxide precipitate is also formed. (f) Plants produce the simple sugar C6H12O6 and oxygen gas from carbon dioxide and water during photosynthesis. (g) Ammonia gas (NH3) is formed along with a precipitate of magnesium hydroxide from the reaction of magnesium nitride powder with water. (h) Strong heating of copper(II) nitrate trihydrate produces copper(II) oxide, nitrogen dioxide, oxygen gas and water.
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.
