How Sodium Decompose Into When Heated Lab Report

Then more roasting occurred when the crucible was placed into a ceramic triangle for the Bunsen burner to continue its burning for an additional 90 minutes. Once the burning was officially over, the crucible was placed onto a ceramic tile to cool off. Next the charcoal and copper material were poured onto a paper towel and were separated from carefully distinguishing them one from the other. Then comparisons were down through analysis of the copper (II) oxide smelted.

In the lab, the theoretical yield of CO2 was calculated by using the mass of the Alka-Seltzer (in Part A) and the mass of the anti-acid (Part B) were multiplied by the mole ratios that were involved in the reaction equation for each reaction and they were also divided by the molar mass of each substance. From the balanced chemical equations that were included in the calculation portion, the limiting reactant in part A was determined to be citric acid. The limiting reactant in part B was determined to be HCl because in the reaction, the HCl would ran out before the calcium carbonate. The stoichiometry would not have been different when converting between the different states of matter because the state is a measure of kinetic energy, and not

However, some reactions are able to form gases such as CO2 when mixing. This is because when double replacement occurs, one of the new reactions made could be a gas or decompose into a gas. This is call a gas evolution reaction. We successfully determined that 2HCl + Na2CO3 and Na2CO3 + H2SO4 would result in gas evolution reactions by doing extra research.

When doing the flame test, if the flame colour of the substance is yellow then it is either sodium chloride or sodium carbonate. The difference between sodium chloride and sodium carbonate is that the first is pH neutral while the latter is basic, which means a pH test would need to be conducted to

If I had a household product labeled sodium bicarbonate, I would add an acidic substance and expect bubble to be created. As we know acid reacts with bubbles when combined with sodium bicarbonate. 2.

Did you know you can turn sodium acetate into “hot ice”? It is exactly what happens within a chemical heating pack! Inside that pack, along with water, is a solution that has more sodium acetate that can normally be dissolved at room temperature. Sodium acetate is the sodium salt of acetic acid. This solution is called a saturated solution because it contains the maximum amount of sodium acetate that can be dissolved without heating the solution (1).

Objective: The purpose of this lab is to show the relationship between chemical decomposition and exothermic reactions, as well as applying the scientific method. This is shown through the construction and launching of popper rockets. Introduction: Crucial things to know are exothermic reactions, Scientific method and chemical decomposition. The scientific method is a series of steps used by scientists to solve a problem.

Weighed 1 gram of NaC2H3O2 and mixed it with ionized water. Boiled 12 mL of 1.0M Acetic Acid added into a beaker containing the sodium carbonate on a hot plate until all the liquid is evaporated

Decomposes into calcium oxide and carbon dioxide when heated to 900°C at 101.325 kPa. Heating calcium carbonate to 900°C under atmospheric pressure decomposes into quicklime and carbon dioxide (industrial CO2 production): (reaction conditions are high temperature ) Calcium carbonate reacts with dilute hydrochloric acid and is effervescent , producing calcium chloride , water and carbon dioxide (CO2 produced in the laboratory): Water mixed with CaCO3 will be fed with excess carbon dioxide and calcium bicarbonate solution will be formed. Calcium Carbonate reacts with a carbonate solution (rainwater) to produce calcium bicarbonate. To the turbid lime water, CO2 was introduced and the precipitate disappeared. The principle of these phenomena is:

While waiting for the water to boil, 100 mL of cold tap water was measured using a graduated cylinder. The cold water was poured into a styrofoam cup its temperature was taken and recorded. Once the water on the hot plate boiled, the thermometer was used to measure its temperature. The temperature of the brass was equal to the temperature of the boiled water.

Abstract: (10 points) This experiment looked at chemicals and their reactions and labeled them if they were either exothermic, endothermic or you couldn’t tell if there was a reaction. It’s important to use those labels, such as endothermic, exothermic, and cannot tell because those labels made it possible so there could be distinctions made on certain solutions and help better understand the behavior of them whether its in an oven or not and it interacts with the air in settings. Introduction: (10 points) Doing the “Chemical Magic” experiment it studied the following: endothermic reaction, exothermic reaction, precipitate, and qualitative analysis, and combustion.

An increase of pressure and temperature was observed to be favorable for the synthesis of carbon phases. Appropriate high pressure and low temperature are favorable for the synthesis of

7 and Fig. 8 respectively. Bicarbonate represents the major form of alkaline, since it is formed in considerable amounts from the action of carbon dioxide upon basic materials in the soil (Sawyer et al
