Answer:
protons and neutrons- second choice
Electric
current passes through a filament of an incandescent bulb, thereby increasing
it temperature. When current flows, it contains electrons through the filament
to produce light. Typically, incandescent light bulb consists
of a glass enclosure that contains tungsten filament. The glass enclosure
contains either a vacuum or an inert gas that serves as the filament protection
from evaporating. Incandescent light bulbs contain a stem attached at to its
base to allow the electrical contacts to run through the envelope without gas
or air leaks.
Atoms. Well, they can be broken down, but that won't happen that fast.
Answer:
A chemical change can be indicated by a change in color, change in temperature (exothermic or endothermic), change in smell, formation of a precipitate, or the formation of gas bubbles.
Explanation:
this should work
Answer:
Oxygen
Explanation:
In the compound tenormin, there are two highly electronegative atoms capable of accepting electrons; oxygen and nitrogen. Oxygen is more electronegative than nitrogen.
However, the oxygen atom in tenormin is bonded to carbon in a carbonyl bond. Recall that the carbonyl bond is polar and the direction of the dipole is towards the oxygen atom. Looking at the structure of tenormin, it is clear that the electron density of the bond tends towards the oxygen atom of the carbonyl group. Electron density is withdrawn from the adjacent nitrogen atom of the amine group via mesomeric and inductive mechanism towards the more electronegative oxygen atom.
On the other side of the structure, there are two oxygen atoms. These oxygen atoms are more electronegative than nitrogen thus they are more basic.
Hence the oxygen atom is the most basic atom in the compound tenormin.
