Answer:
D) winds that blow in the same direction at a consistent speed
Explanation:
i took the quiz got it right so i know the answer please trust me i know this is right i promise with all my heart
The following of the macro molecular collide is all of the above
It’s is a pure substance because nothing is mixed with it and a molecule gas because it’s is a gas and it’s by its self
Ethene react with oxygen at a molar ratio:
Convert the quantity of each reactant supplied to number of moles of particles:
The question stated not whether both reactants were used up in this process. Thus start by testing the assumption that e.g., ethene was used up while some oxygen gas were left unreacted (ethene as the <em>limiting </em>reagent.) Under this assumption, the relative availability of the two species, and (as seen in the balanced chemical equation) shall satisfy the relationship
In other words,
Evaluating the expression with data given in the question yields approximately , which does satisfy the relationship. Hence the assumption holds and ethene is the limiting reactant.
The quantity of a reactant produced in a chemical reaction is related to its stoichiometric (of relating to proportions) relationship with the limiting reactant (or any of the reactants in case of more than one limiting reactant.) For this scenario, given the molar ratio ,
That would be the waxing and waning crescents.
Hope it helps!
