The chemist places 0.25 grams of aluminum foil in a solution of 0.40 grams of copper (II) chloride. A single replacement reaction takes place. What are the likely observations when the reaction stops? Unbalanced equation: CuCl2 + Al → AlCl3 + Cu
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.
A chemist wants to extract copper metal from copper chloride solution. The chemist places 0.25 grams of aluminum foil in a solution of 0.40 grams of copper (II) chloride. A single replacement reaction takes place. What are the likely observations when the reaction stops?
Unbalanced equation: CuCl2 + Al → AlCl3 + Cu
About 0.90 grams of copper is formed, and some aluminum is left in the reaction mixture.
About 0.20 grams of copper is formed, and some aluminum is left in the reaction mixture.
About 0.90 grams of copper is formed, and some copper chloride is left in the reaction mixture.
About 0.20 grams of copper is formed, and some copper chloride is left in the reaction mixture.
