a. Lavoisier was a chemist in the 1700s. He took a very systematic approach tomeasurements in chemistry and is considered to be the "father of modern chemistry."Scientists today also take a very systematic approach by using the scientific method in theirresearch. (6 points) i. Fill in the missing steps of the scientific method. (4 points) A. State the question C. Conduct an experiment E. Analyze the data and draw conclusions ii. What is the purpose of the scientific method? (2 points) b. Through his meticulous experiments, Lavoisier first proposed what is now known as the law of conservation of matter. A similar law developed later, which was called the law of conservation of energy. (6 points) i. What does the law of conservation of energy say? (2 points) ii. List two different kinds of energy. (2 points) iii. What does the law say about changes energy can undergo? (2 points) c. Theories about the structure of the atom have changed as new understanding has been gained. (6 points) i. Describe J. J. Thomson's plum-pudding model of the atom from the late 1800s. (2points) ii. What did Niels Bohr's 1913 model of the atom look like? (2 points) iii. What more accurate model of the atom emerged from Albert Einstein's contributionsand quantum mechanics? (2 points)
