I think the first one and the third. They make more sense as of why waves overlap.
Hope I helped
Answer:
When sugar is dissolved in water, the solution does not conduct electricity, because there are no ions in the solution. Some substances that are made of molecules form solutions that do conduct electricity. Ammonia is such a substance.
Observation : a piece of info we all gather through our 5 senses
Hypotheses: a testable explanation for an observation
Data: info that scientists gather during an experiment
Experiment: a procedure that is designed to test a hypothesis
Conclusion a judgment or decision
Scientific method a series of steps
The empirical formula is the simplest number of atoms each can be reduced to. If we want to find the molecular formula, we need to find the right number of atoms of each that will add to the given mass, in this case, 62.0 grams. In this case, we find the individual masses of each element.
Carbon: 12.011 grams
Hydrogen: 1.008 grams * 3 since there are three
Oxygen: 15.999 grams
When we add these, we get a total mass of 31.034 grams. If we multiply it by two, we get the exact mass of the molecule formula, 62.068. Since we multiplied by two, all molecules have to be multiplied by two. That just means we multiply the number of molecules in the compound by two.
Therefore,
Empirical: CH3O
CH3O*2= C2H6O2 = Molecular
