    Chemistry Write-Up The Thermal Decomposition of Sodium Hydrogen Carbonate Aim: When Sodium Hydrogen Carbonate (NaHCO3) is heated‚ Carbon dioxide and water are given off to leave a white powder. The aim is to find the equations for this reaction. Hypothesis: The experiment will prove which of the equations below is true. It will tell us whether Sodium Carbonate is produced or Sodium Oxide. 2NaHCO3  Na2CO3 + CO2 + H2O 2NaHCO3  Na2O + 2CO2 + H2O Variables: Independent: Original

    investigate the rate of thermal decomposition of CaCO3 at different temperatures. Research Question How does temperature influence the rate of thermal decomposition in CaCO3? Hypothesis Every time more heat is added to the element‚ CaCO3‚ thermal decomposition will take place faster because the heat is a catalyst which speeds up the reaction. Variables Dependent Variables → Mass of Calcium Carbonate Independent Variables → Temperature Controlled Variables → Calcium Carbonate What? How

    AIM: To carry out a lab experiment to decompose a carbonate using heat‚ also to carry out appropriate tests for the formation of products as a result of this decomposition. DISSCUSION: Carbonates are decomposed by heat into the corresponding oxides and carbon dioxide. The temperature of decomposition depends upon the activity of the metal; that is to say‚ the more active the metal‚ the more stable is the carbonate. Thus‚ the carbonates of sodium and potassium are stable at the highest temperature

    Volumetric Determination of Impure Sodium Carbonate (Na2CO3) Introduction: To determine the total amount of carbonate in unrefined sodium carbonate‚ soda ash‚ a titration is done using a standardized solution of HCl. Aqueous HCl is a strong acid and therefore almost completely disassociates into H+ and CL-. Therefore‚ when HCl is used in a titration‚ the H+ is the titrant. Carbonate in aqueous solution is able to accept a proton‚ i.e. it acts as a base. When carbonate accepts the H+ a bicarbonate ion

    Decomposition of Sodium Chlorate Mass‚ Moles‚ and the Chemical Equation Introduction: Sodium chlorate is used as a source of oxygen in emergency oxygen generators. So-called oxygen canisters or oxygen candles are found on airplanes‚ submarines‚ even the space station–anywhere where oxygen might be in short supply in case of an emergency. Sodium chlorate decomposes upon heating or in the presence of metals to give oxygen gas. What the chemical equation for the decomposition of sodium chlorate

    Rate of Decomposition of Calcium Carbonate Theory Calcium carbonate‚ CaCO3‚is one of the most abundant minerals on the Earth. More than 4% of the Earth’s crust is composed of calcium carbonate. It is a major component in limestone‚ marble‚ seashells‚ bedrock‚ etc. Limestone and marble have been among the most widely used building materials for more than 5 000 years‚ from the pyramids in Egypt to the Parthenon in Greece and the Taj Mahal in India. In many places‚ limestone is also the foundation
