Write a molecular equation for the precipitation reaction (if any) that occurs when the following solutions are mixed. If no reaction occurs, write noreaction . 1. potassium sulfate and lead(II) acetate Express your answer as a chemical equation. Enter noreaction if no precipitate is formed. Identify all of the phases in your answer. 2. copper(II) nitrate and barium sulfide Express your answer as a chemical equation. Enter noreaction if no precipitate is formed. Identify all of the phases in your answer. 3. calcium nitrate and sodium iodide Express your answer as a chemical equation. Enter noreaction if no precipitate is formed. Identify all of the phases in your answer.
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.
