Vacuum filtration is more efficient and faster than filtration by the gravity method. But the set up of the vacuum filtration must be precise. Vacuum filtration is done under very reduced pressure hence there should be no gaps around the edges of the filter paper.
For a vacuum to be effective there must be no hole or gap in the equipment. Under vacuum conditions air is removed and the pressure is lowered. If there is gap then air would be continuously supplied and it would be difficult to remove air completely.
As you move across a period, the atomic radii decreases. ... As you move across a period, electrons are added to the same energy level while protons are also being added. The concentration of more protons creates a higher effective nuclear charge.
Answer:
covalent bonds
Explanation:
Nitrogen atoms will form three covalent bonds (also called triple covalent) between two atoms of nitrogen because each nitrogen atom needs three electrons to fill its outermost shell.
(if it is still confusing i have another way of explaining so jus let me know :)
1. 100N to the right
2. 10N to the left
3. 0N they are balanced
4. 0N they are balanced
1. Two parallel normal faults form.
4. The hanging wall on the left slides down relative to the footwall.
5. The hanging wall on the right slides down relative to the footwall.
