TASK 2: Answer ME! Directions: Read and understand the following questions and write the letter of the correct answer in a clean sheet of paper. 1. Which forces of attraction are present in the mixtures of ionic compounds and polar compounds? A. Dipole-Dipole Forces C. Ion-Dipole Forces B. Hydrogen Bond D. London Dispersion Forces 2. Which among the molecules has highest London dispersion forces? В. С12 — 34 е- A. F2 – 18 e- C. Br2 – 70 e- D. 12 – 106 e- 3. Which of the following is NOT true about Dipole-Dipole Forces? A. Forces of attraction between a cation or anion and a nonpolar molecule. B. Attractive forces between polar molecules. C. The partial negative side of a molecule is attracted by the partial positive side of another molecule. D. This force is stronger than the London Dispersion Forces but weaker than Ion-Dipole Forces and Hydrogen Bond.
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.
