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

chemically convert the substance into nutrients. It usually involves mechanical manipulation and chemical action. Mechanical Digestion What is it? This type of digestion involves the mixing‚ grinding or crushing of large pieces of food into smaller places. Why does it take place? So that the food we consume is broken down into smaller pieces before we swallow it which in turn makes process of chemical digestion that takes place later on more effective because it works more efficiently on

Gonzales Mrs. Krametbauer English III 10 November 2014 Why Chemical Engineering? Individuals take engineering as something distance to their lives due to rigorous courses to get through. As some would say that it is not worth it‚ other clever individuals have figured this out. To be a chemical engineer‚ an individual explores and takes on other sciences to create important products to better peoples lives. As Mark and Sherri Devaney stated‚ “…Chemical Engineers are charged primarily with finding ways to

BEAUTY WITHOUT CHEMICALS When we talk about beauty‚ the first thought that comes to our mind is about how we look physically especially our face. Well I would like to talk on taking care our facial skin without any chemicals which means we use natural sources instead of fancy artificial chemicals. It is always better for us to consume as the chemicals usage in long run do give negative effects. Based on the research from in the internet‚ advices from other as well as from my own experience‚ I

Describe the difference between a mixture and a compound. A compound is a substance in which atoms of different elements are chemically held to one another. A mixture is a substance made by combining two or more different materials in such a way that no chemical reaction occurs. A mixture can usually be separated back into its original components‚ a compound cannot. Below are some examples of the differences between each. Compounds •Compounds are pure substances. •They are made up of two or more elements

04/02/14 Date Submitted: 04/15/14 Name: Lisa Jacoby Title: Physical and Chemical Properties Purpose: Investigating the chemical properties of pure chemical substances as well as exploring the physical properties of pure chemical substances Procedure: 1. I half-filled one well of a 24-well plate with 6M HCl and half-filled a second well of the 24-well plate with 6 M NaOH. I then sucked up these chemicals into their labeled pipets. I then set aside for later 2. I performed the following
