Answer:
the nucleus of the atom was centrally located i n the atom and was positively charged
Explanation:t
11.412 x 10^23.
EXPLANATION:
5.5 oz = 155.92 g
155.92 g x (1 mol/82.2 g) = 1.8956 mol
(6.02 x 10^23) x 1.8956 = 11.412 x 10^23
Answer: Thus 8.41 g was the mass of the original sample
Explanation:
To calculate the moles :
According to stoichiometry :
As 3 moles of 
are produced by = 2 moles of 
Thus 0.103 moles of are produced by =
of
Mass of 
Thus 8.41 g was the mass of the original sample.
Answer:
33km due south
Explanation:
Morant Bay is 33km south of Port Antonio;
Problem: displacement of Morant bay from Port Antonio;
Displacement is a vector quantity. It is the length of path between two position and the direction inclusive.
So, it has magnitude and must be specified with a direction.
- Therefore, the displacement of Morant Bay from Port Antonio is 33km due south.
