Answer:
The answer to your question is 0.6 M
Explanation:
Data
Molarity = ?
Volume = 450 ml
mass of NaCl = 15 g
Process
1.- Calculate the molar mass of NaCl
NaCl = 23 + 35.5 = 58.5 g
2.- Calculate the number of moles of NaCl
58.5 g of NaCl ------------ 1mol
15 g of NaCl ------------ x
x = (15 x 1)/58.5
x = 0.26 moles
3.- Calculate the molarity
Molarity = moles/volume
-Substitutiion
Molarity = 0.26/0.45l
-Result
Molarity = 0.6 M
Answer:
gas
Explanation:
The gas molecules are far apart and as such, when heated they gain more kinetic energy thereby colliding with one another and with the wall of the container thereby exerting pressure and also they can be compressed by reducing the distance between between the molecules.
Answer:
Vanderwaals forces
Explanation:
CBr4 is a nonpolar molecule, nonpolar molecules usually possess vanderwaals forces between their molecules as their main attractive force.
CBr4 is nonpolar because the tetrahedral arrangement of the C-Br bonds cancel out the individual dipole moments of each C-Br bond thereby making the compound nonpolar, hence the answer above.
The compound given (i.e. 3,3-dimethyl-1-butanol) is primary alcohol (1°) because the functional group (-OH) shows that it is alcohol is attached to a primary carbon (i.e terminal carbon).
The oxidation of all primary alcohols results in the formation of aliphatic aldehyde(also known as alkanal).
Suppose, it is secondary alcohol;
The oxidation of secondary alcohol results in the formation of ketone(also known as alkanone).
When 3,3-dimethyl-1-butanol undergoes oxidation, the suffix "ol" in the alcohol changes to "al"
Therefore, 3,3-dimethyl-1-butanol changes to 3,3-dimethyl-1-butanal after undergoing oxidation.
In conclusion, the product when 3,3-dimethyl-1-butanol undergoes oxidation is: 3,3-dimethylbutanal.
As such, option 2 is correct.
