LAB REPORT Introduction: In a chemical change‚ the identities of substances change and new substances form. In an equation the substances on the left are the reactants. The substances on the right are the products. In this experiment the objectives are to observe evidence that a chemical change has taken place. Infer from observations that a new substance has been formed. Identify and record observations that show energy is involved in chemical change observe the color‚ solubility of some substances

The Red Panda comes from the family of Ailuridae and its scientific name is Ailurus Fulgens. The Red Fox‚ whose scientific name is Vulpes Vulpes‚ is from the Canidae family. They are both mammals and are the same size. However‚ the Red Panda and the Red Fox share similarities and differences in their appearance‚ habitat‚ diet‚ behaviour‚ reproduction and status of population. First of all‚ the Red Panda and the Red Fox are quite similar but a little different in their appearance. Like the Red

Calorimetry To determine the specific heat of a metal and its approximate atomic mass. To determine the heat of neutralization for a strong acid-strong base reaction. To determine the quantity and direction of heat flow for the dissolution of salt. Post Lab Questions and Answers: 1. In parts A and B in‚ the calorimeter‚ although a good insulator‚ absorbs some heat when the system is above room temperature. Is the reported value for the specific heat of the metal too high or too low? Explain. Is the reported

while 100 mL of base‚ stock solution of NaOH‚ was placed in another burette. 25 mL of KHP was placed into the Erlenmeyer flask‚ which was also recorded as the volume of acid in the flask. A total of 19 mL of base‚ NaOH‚ was required for the endpoint‚ which was indicated by a very pale pink color. To calculate the molarity of NaOH‚ the following equation was used MNaOH x VNaOH = MKHP x VKHP therefore the molarity was .125 M. INTRODUCTION This lab experiment covers the preparation of standard
