Answer

This guide provides concise steps and formulas for each topic. Explanation 1. Name Ionic and Covalent Compounds Identify ionic compounds by metal-nonmetal combinations and covalent compounds by nonmetal-nonmetal combinations. 2. Find the Molar Mass of Compounds Sum atomic masses from the periodic table for each element in the compound. 3. Identify Reactants and Products in a Reaction Reactants are on the left side, products on the right side of the reaction arrow. 4. Significant Figures Use the least number of significant figures from any measurement in calculations. 5. Types of Chemical Reactions Include synthesis, decomposition, single replacement, double replacement, and combustion. 6. Draw and Identify Free Body Diagrams Represent forces acting on an object with arrows indicating direction and magnitude. 7. Calculate Net Force **F_{\text{net}} = \sum F_i**; sum all forces acting on an object. 8. Calculate Forces on an Incline Use components parallel and perpendicular to the incline: **F_{\parallel} = mg\sin(\theta)**, **F_{\perp} = mg\cos(\theta)**. 9. Newton's First Law of Motion An object remains at rest or in uniform motion unless acted upon by a net external force. 10. Use Periodic Table to Find Charge of Elements Metals typically lose electrons (positive charge), nonmetals gain electrons (negative charge). 11. Balance Chemical Equations Adjust coefficients to have equal numbers of each type of atom on both sides of the equation. 12. Difference Between Mass and Weight Mass is the amount of matter (kg), weight is the gravitational force on that mass (N). 13. Calculate Frictional Force **f = \mu N**; where \mu is the coefficient of friction and N is the normal force. 14. Use Net Force to Find Net Acceleration **a = \frac{F_{\text{net}}}{m}**; divide net force by mass.
