The liquid substances mercury (density = 13.6 g/ml), water (1.00 g/ml), and cyclohexane (0.778 g/ml) do not form a solution when mixed, but separate in distinct layers. list how the liquids would position themselves in a test tube.

What element is used to make expensive forks spoons and tableware?

What is the mass number of an atom of 5 protons and 7 nuetrons

Okay so I'm trying to understand something for my CER. I did a lab on objects that have an equal mass but volume and density vary. Now I need to defend why the volume increased and the density decreased.

A flask contains 0.83mol of neon gas at a temperature of 35°C. The pressure gauge indicates 0.37atm inside the flask. What is the volume of the neon gas?
