The answer is B that is sound wave. Sound wave required a medium to travel.
Mechanical wave is not capable of transfer its energy through vacuum . It required a medium to travel and sound wave is an example of mechanical wave that required a medium to travel.
So, All other wave that are listed here doesn't required a medium to travel, among all only sound wave requires a medium to travel.
In chemistry, yes...yes it is.
12 moles H2O
Explanation:
Your tools of choice for stoichiometry problems will always be the mole ratios that exist between the chemical species that take part in the reaction.
As you know, the stoichiometric coefficients attributed to each compound in the balanced chemical equation can be thought of as moles of reactants needed or moles of products formed in the reaction.
