the water molecules stay together keeping the shape of the balloon. In the water molecule, the oxygen and hydrogen atoms share electrons in covalent bonds. There are a total of 10 protons and 10 ...

A balloon filled with hydrogen gas also releases heat when lit on fire. Due to differences in energy density, the crystallization of sodium acetate releases more heat per mole than the hydrogen gas ...
