The elemental analysis of a substance is 37.51% C, 3.15% H, and 59.34% F. Based on the elemental analysis and the mass spectrum provided, what is the molecular formula?

Here’s one way to follow the scientific method. place the missing steps in the correct position in the process

Light waves travel than sound waves.

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?
