I. Introduction: The purpose of this lab report is to differentiate between of Newton’s Third Law and Newton’s Second Law. Newton’s Third Law states that all forces come in pairs and that the two forces in a pair act on different objects and are equal in strength and opposite in direction. Newton’s Second Law states that the acceleration of an object is proportional to the net force and inversely proportional to the mass of the object being accelerated. Using calculation equations for acceleration

The Mammalian Urogenital Lab Questions 1. The urine needs to be stored in egg-laying animals so that the fetus is not trapped in pools of urine inside of the egg. This keeps the urine separate from the fetus and its nutrients. 2. The fetuses of mammals that bear their young alive do not need a urine sac and does not form urine because all of the fetuses waste is taken out through the mother either through the placenta or the umbilical cord. 3. The testes are separated from the abdominal

Stoichiometry lab 1 Purpose: The purpose of this lab is to find the limiting reactant‚ also to find the percentage yield and percentage purity of the reaction that happens between Calcium Chloride and Sodium Carbonate. The other purpose was to know how the reaction can be balanced and created. Hypothesis: In this lab we are going to see a precipitation reaction. This is a reaction where two soluble salts Sodium Carbonate and Calcium Chloride are added together and the result is the precipitation
