Answer:

A. A broad, well-supported explanation of related observations or events

Explanation:

A scientific theory is a detailed reasoning of a well supported observation or experiment. Though, not just anyone can create a scientific theory... it has to be widely accepted throughout the scientific community!

A law on the other hand, is simply a description of things that happen in the natural world. It doesn't quite say why, with a law, it just is what it is! Laws don't become theories and theories do not become laws!

I hope I was of assistance! Science can be difficult! Have a nice day and spread the love <3

Find the empirical and the molecular formula of acetylene gas composed of 92.26 percent carbon and 7.74 percent hydrogen

Hitman42 [59]

Answer:

Explanation:

92.26% = 92.26 g

7.74% = 7.74 g

carbon is 92.26 x 1 mole/12.011 = 7.68

hydrogen is 7.74 x 1 mole/1.008 = 7.68

carbon 7.68 ÷ hydrogen 7.68 = 1

so 1 is your subscript for both carbon and hydrogen
