A chem....rking as a safety inspector finds an unmarked bottle in a lab cabinet. A note on the door of the cabinet says the cabinet is used to store bottles of tetrahydrofuran, chloroform, ethanolamine, diethylamine, and pentane. The chemist plans to try to identify the unknown liquid by measuring the density and comparing to known densities. First, from his collection of Material Safety Data Sheets (MSDS), the chemist finds the following information: liquid density tetrahydrofuran -1 0.89 gmL -1 1.5 g•mL chloroform ethanolamine 1.0 g•mL¯ diethylamine - 1 0.71 g•mL pentane - 1 0.63 g mL Next, the chemist measures the volume of the unknown liquid as 1062. cm° and the mass of the unknown liquid as 1.08 kg. Calculate the density of the liquid. Round your answer to 3 significant digits. 1 g•mL Given the data above, is it possible to identify the liquid? yes no tetrahydrofuran chloroform If it is possible to identify the liquid, do so. ethanolamine diethylamine pentane

Carbon disulfide and oxygen react to form carbon dioxide and sulfur dioxide, like this: CS₂(g)+30₂(g) → CO₂(g) +2SO₂(g) perturbation Some O₂ is removed. Some CO₂ is added. Suppose a mixture of CS₂, O₂, CO₂ and SO₂ has come to equilibrium in a closed reaction vessel. Predict what change, if any, the perturbations in the table below will cause in the composition of the mixture in the vessel. Also decide whether the equilibrium shifts to the right or left.

How can you use technology to enhance teaching and learning in a 5th grade classroom for a lesson on mixing substances based on the below standard and learning objective? (Optional: Use the SAMR model to explain the technology integration strategies you plan to use.) Standard Conduct an investigation to determine whether the mixing of two or more substances results in new substances. Learning Objective Given a variety of substances and safety equipment in a classroom setting, students will be able to conduct an experiment to mix two or more substances and observe the results. They will be able to correctly identify whether a new substance has been formed as a result of the mixing, based on observable changes such as color change, formation of a precipitate, or change in temperature, with at least 80% accuracy.
