Ernest is a PhD candidate in the Department of Chemistry at Memorial University of Newfoundland, Canada. His research lies at the intersection of computational biochemistry and drug discovery. The main focus of his research is to identify druggable targets in proteins to assist drug developers and medicinal chemists in designing better drugs for therapeutic purposes. Ernest holds a BSc (Hons) degree in Chemistry from Mount Allison University, Canada. Outside school, Ernest enjoys volunteering and staying active. He has coached youth soccer and has been involved with community development projects across the globe, with organizations such as Canada World Youth (Jeunesse Canada Monde), Doctors Without Borders (Médecins Sans Frontières), and Students Offering Support.
Two samples of carbon tetrachloride are decomposed into their constituent elements. One sample produces 38.9 g of carbon and 448 g of chlorine, and the other sample produces 14.8 g of carbon
and 134 g of chlorine. Are these results consistent with the law of definite proportions? Show why or why not.
Sulfur and oxygen form both sulfur dioxide and sulfur trioxide. When samples of these are decomposed, the sulfur dioxide produces 3.49 g oxygen and 3.50 g sulfur, while the sulfur trioxide produces 6.75 g oxygen and 4.50 g sulfur. Calculate the mass of oxygen per gram of sulfur for each sample and show
that these results are consistent with the law of multiple proportions.
