Student 1you are supplied with a 100 ml beaker that you weigh on a pocket balance – its weight clean and dry is 29.3 g. you then dispense 15.0 ml of a clear unknown liquid from a graduated cylinder into the 100 ml beaker. the beaker plus liquid now weighs 44.2 g. calculate the density of the liquid on the sheet supplied with your data sheets.

What is the mass defect of a mole of nuclei with 1.8 x 10^15 j/mol binding energy?

How far is the region from the equator or control climate

Sulfur dioxide and oxygen react to form sulfur trioxide during one of the key steps in sulfuric acid synthesis. an industrial chemist studying this reaction fills a 25.0l tank with 4.5 mol of sulfur dioxide gas and 4.5 mol of oxygen gas at 30.°c. he then raises the temperature, and when the mixture has come to equilibrium measures the amount of sulfur trioxide gas to be 1.4 mol. calculate the concentration equilibrium constant for the reaction of sulfur dioxide and oxygen at the final temperature of the mixture. round your answer to 2 significant digits.
