1. Your lab procedure says measure exactly 100 g of sugar then add it to the solution, describe in detail how you would complete this step, make sure you state the specific lab equipment you would use to accomplish this task. 2. Describe the steps you would take to separate a mixture of sugar and sand? What specific properties would you consider as you develop your procedure?

In numbering carbon atoms in the parent chain of a hydrocarbon, why would you number from right to left, rather than left to right

How have the greenhouse gasses increased from the year 2000 to 2018

There are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of several useful plastics. in the first step, calcium carbide and water react to form acetylene and calcium hydroxide: cac2 (s) + 2h2o (g) → c2h2 (g) + caoh2 (s) =δh−414.kj in the second step, acetylene, carbon dioxide and water react to form acrylic acid: 6c2h2 (g) + 3co2 (g) + 4h2o (g) → 5ch2chco2h (g) =δh132.kj calculate the net change in enthalpy for the formation of one mole of acrylic acid from calcium carbide, water and carbon dioxide from these reactions. round your answer to the nearest kj .
