• List the types of chemical reactions, include the generic equations (go back to the video in Module 9 about Types of Chemical Reactions if you need to refresh your memory, here is more practice, if you want to master the topic) Classify the following chemical reactions in all possible ways (some of the chemical equations are not balanced, do NOT worry about it): . C(s) + O₂(8)→→→→→ CO₂(g) - Na(s) + Cl₂(g) →→→ NaCl(g) H₂(g) + O₂(8) O H₂O(1) CaCO3(s) CaO(s) + CO2(g) CH4(8) + O₂(8) O C3H8(8)+ O2(8) O O O O - O - C₂H5OH()+ O2(8) CO₂(8) + H₂O(g) CO2(8)+ H₂O(g) CO₂(g)+ H₂O(g) Cu(s) + FeCl₂(aq) Ag(s) + Cu(NO3)2(aq) -BaSO4(s) + NaCl(aq) AgBr(s) + KNO3aal Fe(s) CuCl₂(aq) O Cu(s) AgNO3(aq) O BaCl₂(aq) Na₂SO4(aq) o KBr(aq) + AgNO3(aq) +
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.
