Maggie measures the volumes and masses of various substances and records her observations in the table. Volume (cm3) Mass (g)
Liquid A 10.0 16.0
Liquid B 10.0 13.0
Cube A 22.0 20.0
Cube B 9.0 14.0
What can Maggie correctly predict about the relationship between the liquids and the solids?

What is the chemical formula of the following compound

Element before carbon on the periodic table

Hydrogenation reactions, in which h2 and an "unsaturated" organic compound combine, are used in the food, fuel, and polymer industries. in the simplest case, ethene (c2h4) and h2 form ethane (c2h6). if 140 kj is given off per mole of c2h4 reacting, how much heat (in mj) is released when 12 kg of c2h6 forms?
