Chemical Reactions Lab Synthesis Reactions: Synthesis reactions occur when two elements or compounds combine to create one single compound. The general equation of synthesis reactions is: A+B→AB. The following are the complete balanced equations for the five synthesis reactions performed in the lab. Reaction 1: Reaction 2: Reaction 3: Reaction 4: Reaction 5: The reaction of CO2 and water is a prime example of a synthesis reaction. This is a synthesis reaction because it follows the general

Post-Lab Questions 1. Using the information provided in the Introduction and your observations from Part 1‚ hypothesize as to the type of electrolyte the following solutions would be. Justify the hypothesis from a chemical standpoint. a. Aqueous Sodium Hydroxide—NaOH (aq) is a very strong base‚ which will completely disassociate into Na+ and OH- ions‚ which would make it a very strong electrolyte. Chemical reaction of the disassociation of Sodium Hydroxide: NaOH (aq)Na+ (aq)+ OH-(aq)

The percent error was determined to be 76.0%. Introduction: The purpose of this lab is to investigate vapor pressures and the partial pressure of gas produced from liquids at different temperatures. These pressures vary at different temperatures. In any given liquid there is a vapor that is produced above directly above the liquid‚ this can be determined intuitively from smell. (Do not smell the liquid used in this experiment‚ denatured alcohol is harmful) At a given temperature the evaporation

Science Lab- Determining the Most Effective Antacid Robby Grewal SNC2D0 Introduction: Heartburn is a form of indigestion by acid digestion it affects many people worldwide. A solution to defeat heartburn is to take an antacid. An antacid is medicine which neutralizes your stomach acidity. In this experiment‚ we will be using three liquid antacids which are Phillips Milk of Magnesia‚ Life Brand Milk of Magnesia and Diovol plus AF and determine which one is the most effective at neutralizing

Experiment 1: Density | Purpose: To determine the density of the following liquids and solids. Data/Observation: Part A Sample | Distilled Water (g) | Methanol (g) | Glycerol (g) | Mass of empty cylinder | 41.1 g | 40.4 g | 41.1 g | Mass of cylinder + liquid | 51.2 g | 48.2 g | 53.8 g | Mass of liquid | 10.1 g | 7.8 g | 12.7 g | Calculations: Density of liquid = Mass/Volume = g/mL Distilled Water = 10.1g/10mL = 1.01 g/mL Methanol = 7.8g/10mL = 0.793 g/mL Glycerol = 12.7g/10mL
