A student finds the mass of an empty 50-mL beaker to be 36.52 g. She then uses a 25.0- mL volumetric pipet to transfer a sample of an organic liquid to the beaker. The beaker and its contents now have a mass of 53.25 g. what is the density of the liquid? ​

Identify a strong intermolecular force of attraction between an alcohol

Liquid ammonia is produced at high temperatures and under great pressure in a tank by passing a mixture of nitrogen gas and hydrogen gas over an iron catalyst. the reaction is represented by the following equation. n2(g) + 3h2(g) → 2nh3(g) changing all but one experimental condition will affect the amount of ammonia produced. that condition is a) increasing the concentration of both reactants b) changing the temperature within the tank c) decreasing the pressure within the tank. d) increasing only the amount of nitrogen present.

Scientists often deal with numbers that are either very large or very small. for example, the radius of the sun is approximately 696,000 kilometers, while bacterial cells are as small as 1.9 × 10-4 millimeters. express each of these numbers in an alternate form.
