Candle Reaction Lab

- Results: When a lighted match was held 2cm away from the unlighted candle in its smoke, the flame would jump from the match to the wick having been carried by the smoke.

Combustion Reaction: A chemical reaction between a fuel and an oxidizing agent that produces heat.

Reactants collide with each other so new bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make new products

In a combustion reaction, a compound or element reacts with oxygen, releasing a large amount of energy in the form of light and heat.

Purpose: The purpose of this experiment is to observe a variety of chemical reactions and to identify patterns in the conversion of reactants into products.

Try to repeat the experiment to compare the weight of the candle instead of its height. Do you think there will be any difference in your findings?

The purpose of the lab was to determine the ratio of air to acetylene results in complete combustion of acetylene gas. The balanced chemical equation for this experiment was C2H2(g) + O2(g) --> CO2(g)+ H2O(l). Complete combustion is the reaction of an element or compound with oxygen to produce the most common oxides and energy. Complete combustion occurs when the fuel and oxygen combine in exact proportions to completely burn the fuel, which leaves a clean test tube. Incomplete combustion is the reaction of an element or compound with oxygen to produce some oxides with less oxygen than the most common oxides. Incomplete combustion occurs when there is not enough oxygen to react

Although oxidation is the end process of combustion, the same is not true for oxidation. After complex chemical reactions, combustion is paired with an exothermic reaction. Enthalpy in the form of heat is created during this process. “The rate or speed at which the reactants combine is high, in part because of the nature of the chemical reaction itself and in part because more energy is generated than can escape into the surrounding medium, with the result that the temperature of the reactants is raised to accelerate the reaction even

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.

The overall goal in this lab was to oxidize borneol, a secondary alcohol, into camphor, which is a ketone. For the purposes of oxidation chromic acid was utilized, which was prepared by adding a 1:1 ratio of chromium trioxide to dilute sulfuric acid.

Introduction We wondered if the what would happen if we put a candle in a pan with a stand and a lid with water. Then we formed a hypothesis. We wondered if the amount on candles lit would affect the amount of water sucked up from the candle. We are asking this question because we wanted to know the answer and see what would happen. Experimental design

”("BBC - GCSE Bitesize: Combustion", 2017). Complete combustion gives off more energy as heat and is ideal but was unlikely under the test conditions. Complete combustion requires a decent supply of oxygen to react with. If these conditions aren’t met incomplete combustion occurs and “water is produced, but carbon monoxide and carbon are produced instead of carbon

A chemical reaction is when substances (reactants) change into other substances (products). The five general types of chemical reactions are synthesis (also known as direct combination), decomposition, single replacement (also known as single displacement), double replacement (also known as double displacement), and combustion. In this lab, the five general types of chemical reactions were conducted and observations were taken before, during, and after the reaction. Then the reactants and observations were used to determine the products to form a balanced chemical equation. The purpose of this lab was to learn and answer the question: How can observations be used to determine the identity of substances produced in a chemical reaction?

Introduction: This experiment aims to discuss whether the thickness of a candle influences the time of burning. A candle burns by melting the wax near the wick. This liquid wax is then drawn up the wick by capillary action. The heat of the flame then vaporises the wax. Previous results showed that wider candles burnt slower than thinner candles.

A chemical reaction is a process in which elements or compounds react with one another to create new or different substances. There are two parts to a reaction. Those two parts are the products and the reactants. The reactants are the chemicals or chemical compounds that are going through the reaction itself. The products are chemical elements or chemical compounds that are produced as a result of the reactant or reactants reacting. There are four key indications that there’s a chemical reaction is taking place. Those four signs include a change in color and/or odor, formation of a precipitate or a gas, the release or absorption of energy (light, heat, electricity), and if the reaction is irreversible. Along with this information, there are ways to predict the products of a reaction.
