Candle Burning Lab

chemical scoop, metric ruler, lab countertop, rubber stoppers, safety goggles, lab apron Materials- candle ( 2cm diameter), matchbook, 2 toothpicks, Limewater solution, string, aluminum foil, Cobalt Chloride paper Procedure: Note appearance, odor, and feel of the unlighted candle. Heat the bottom of the candle and secure it to a cardboard square on your lab counter. Light the candle and allow it to burn for several minutes. Note any changes. Briefly describe the burning candle. Blow out the flame and

with a Candle Justin Nguyen Mrs. Howley 11/16/11 Mod F Purpose: the purpose is to learn how the process of a candle burning. The goals of this experiment are to practice in the art of observation, the art of questioning, and the development of a better understanding of this process. Hypothesis: through this experiment, we will learn how candle is working. Materials: * Candle * Note card * Matches or butane lighter * Aluminum foil * 1L beaker * Balance I. Candle Observation

Mass-Valderrama CHM1032 summer ‘12 Graphing and Estimating Formal Lab Report Introduction: Today scientists put acquired data into a form of a graph. This said graph is designed to help make predictions and furthermore, study and understand the experiment and its contents at hand. The Graphing and Estimating lab involves just that. The lab is designed to collect data from several tests involving burn time of a candle. Oxygen, O2, is a kind of gas. A lot of the air we breathe as human

Abstract/Introduction The definition of burning is a rapid combustion that gives off light and heat. Burning is a chemical change for new substances are created that cannot changed back are formed. Oxygen is needed for combustion or also called rapid oxidation. When oxygen is added, it causes a fire to burn hotter and faster. In this lab both wood and steel wool were burned in pure oxygen and air. Wood is mixture of many substances but for this lab we will focus on the cellulose aspect for the

physical changes. Materials: - lab balance - microspatula - lab burner - dropper pipet - 5 test tubes - mortar and pestle - test tube rack - magnet - test tube holder - insulating pad - watch glass - safety goggles - glass square - lab apron or coat - copper sulfate pentahydrate - iron fillings - sodium chloride - magnesium ribbon - hydrochloric acid - paper (5 cm x 10 cm) - silver nitarate - birthday candle - sulfur - matches Procedure:

This lab was not very fun, but it helped in learning the information. After this lab I learned how to find the heat gained/lost and I also learned how to calculate the heat of combustion of the candle and the molar heat of combustion of paraffin. Going into this lab I had no idea what these terms meant. After research, I discovered that heat of combustion is the amount of energy released in burning completely one mole of substance. My hypothesis heading into this experiment was that the closer

Chemical Changes VS Physical Changes Lab Report (Full Name) 3rd period Purpose: To observe the difference between chemical and physical changes.

Kayla Sosa 12/8/2017 A chemical reaction is a process by which atoms of one or more substances are rearranged to form a different substance. Six types of chemical reactions are Synthesis, Combustion, Decomposition, Single Replacement, Double Replacement, and Acid/Bases. Each of these does something different, some combine to make a new product and some break down to make new products. Synthesis reaction is a type of reaction in which multiple reactants combine to form a single product. A description

for hedonic products. Pretesting of measures and questionnaire A pre-test is conducted in a retail shop where sells functional & scented candles. We generate a convenience sample from 50 real customers as respondents regarding their perceptions towards candles. The questionnaire offers various options for respondents to express their preference for candle brands, functions, flavours, scents, prices and purchase experiences and frequencies etc. The results from pre-test are able to help generate

A: Ladies and Gentlemen; today is a big day in our Optic Clinic! The cramped room with damp patches on its walls, the old wet underground, so-called lab of Dr. Harrison has now turned into a labyrinth which owes its worldwide reputation to the efforts of this giant figure in the field of medicine. B: Our clinic has made a breakthrough throughout these years and in this age we are one of the most equipped hospitals providing services for citizens of our native land and of course foreign patients
