Answer:
The net force on a vehicle that is accelerating at a rate of 1.5
The net force on a vehicle that is accelerating at a rate of 1.5 m/s2 is 1,800 newtons.
Explanation:
Answer:
Two electrons fit in the first shell out from the nucleus and eight fit in the second. Every element with more protons than the two of Helium needs to work on shells outside the first one. one you get to ten, you have filled the first two shells.
In a water molecule, oxygen forms one covalent bond with EACH of TWO hydrogen atoms. As a result, the oxygen atom has a stable arrangement of 8 valence electrons. Each hydrogen atom forms only one bond because it needs only two electrons to be stable.
Answer:
The supersaturated solution
it is a solution usually very sugary
excess solute
the supersaturated solution is a solution
where there is solute and solvent, there is always interaction
Explanation:
The supersaturated solutions are solutions where the solute is in excess, the solute is in constant interaction with the solvent and being in excess it precipitates to the bottom of the solution.
A supersaturated solution has a very high osmolarity.
Answer:
Physical change
Explanation:
Physical change -
It is the type of reversible change , where there is change in the state of the matter , is referred to as a physical change .
There is no chemical process involved during state change , i.e. , no new substance is formed .
Hence , from the given statement of the question, the correct term is physical change.
Step 1: Esterification: Butyric Acid is treatet with ethanol in the presence of Acid. The corresponding intermediate formed is Keto Ester (Ethyl Butyrate) and serves as a synthetic intermediate. (Highlighted RED in scheme).
Step 2: Nucleophilic Substitution Reaction:The corresponding Ester formed is treated with Methyl Magnesium Bromide. And after hydrolysis 2- Pentanone is synthesized. The r2 step reaction is shoen belo.
