Explanation:
A Lewis structure or dot electron structure is a representation of an atom in which the valence electrons on the outermost shell of the atom are represented as dots.
These dots show the number of valence electrons as well as the group to which the atom belongs in the periodic table.
Answer:
2.67761514 moles
Explanation:
0.075kg equates to 75g.
This means that the car emits 75g of CO per km.
dividing 75g by the molar mass of CO (28.01g/mol) we get 2.67761514 moles
The answer would possible be letter a
The given (2.50mol), is multiplied by the molar mass of Iron(II)Hydroxide, which is 89.86 grams, so the equation would be
89.86x2.5=224.65g/mol
Hope this helps!
Your answer is D. Crust Because earthquakes only happen on the surface. And even underneath ocean waters. Which is what causes tsunamis. But it is still considered the crust.
