I believe the answer is C. an increase in the number of cold climates
the perpendicular component will be = Wy
Wy = w * cos 42.34 = 48.11 N x cos 42.34 = 35.54 N
It can help with measurements and when you want to add measurements to a cylinder or a beaker so ya
Answer:
PE = (|accepted value – experimental value| \ accepted value) x 100%
Explanation:
The aluminum atom_loses_____electrons to form an ion.
The ion that is formed is_Al³⁺_____.
aluminium has the electronic configuration as 1s² 2s² 2p⁶ 3s² 3p¹
from the electronic configuration , we see that aluminium can attain stability by losing 3 electrons from outer shell.
after losing 3 electrons , the ion formed is given as Al³⁺
hence the correct options to fill in the blanks are lose and Al³⁺
