Calculation on the molar enthalpy change of a neutralization reaction Principle H2SO4(aq)+2NaOH(aq)=Na2SO4(aq)+2H2O(l) The reaction is a exothermic reaction‚ when the heat released by it is absorbed by water‚ the temperature of the water increases. The heat produced by the reaction can be calculated if it is assumed that all the heat is absorbed by the water. Heat change of reaction=-heat change of water =-mH2O×cH2O×△TH2O As the water has gained the heat produced by the reaction‚ the heat change

By Kate Dance “Torching Tiny Teddies” Energy Efficiency Experiment Aim: To test the energy efficiency of a tiny teddy in kilojoules by burning the tiny teddy beneath a test tube of water. The water temperature is then measured to see how efficient the transformation of energy is. It is important to see how efficient the transformation is as it will give an indication to whether burning tiny teddies would be an efficient source of energy. Hypothesis: It was hypothesised that the temperature would

Variables Independent variable: The temperature of HCl is going to be changed. The temperature 10℃‚30℃‚50℃‚70℃ and 90℃ of hydrochloric acid will be used to conduct the experiment. The hot plate is going to be used to reach 30℃‚50℃‚70℃ and 90℃‚ that are higher than the room temperature. Ice cubes can be used with water bath to make 10℃ hydrochloric acid. Dependent variable: The time it takes for carbon dioxide gas produces up to 20mL of gas syringe is going to be measured. It will be measured

Chemical equilibrium is the point at which the concentrations of reactants and products do not change with time. It would appear as if the reaction has stopped‚ but in fact‚ the rates of the forward and reverse reactions are equal‚ causing the reactants and products to be created at the same rate. This can be expressed mathematically in the form of the equilibrium constant. The following is the general equation for a reversible chemical reaction: aA+bB →cC+dD
