Answer:
The number 10,847,100 in Scientific Notation is
Explanation:
Scientific notation is an easy form to write long numbers and it is commonly used in the scientific field. To write a long number in a shorter way it is necessary to 'move' the decimal point to the left the number of positions that are necessary until you get a unit. Then you write the number and multiplied it by 10 raised to the number of positions you moved the decimal point. In this case, it is necessary to move the decimal point 7 positions so, we multiply the number by 10 raised to 7.
The given question is incomplete. The complete question is as follows.
A solution of chloroform () and acetone (
) exhibits a negative deviation from Raoult's law. This result implies that:
chloroform-chloroform interactions are stronger than chloroform-acetone interactions.
chloroform-chloroform interactions are weaker than chloroform-acetone interactions.
acetone-acetone interactions are stronger than chloroform-acetone interactions.
acetone-acetone interactions are weaker than chloroform-acetone interactions
chloroform-chloroform interactions are weaker than chloroform-acetone interactions AND acetone-acetone interactions are weaker than chloroform-acetone interactions.
Explanation:
It is known that when the forces between the particles of the mixture are stronger than the forces between the particles in the pure liquids then negative deviations from Raoult's law are observed.
Hence, when a solution of chloroform () and Acetone (
) will exhibit a negative deviation from Roult's law.
Then, chloroform-chloroform interactions should be weaker than chloroform-acetone interactions and acetone-acetone interactions must be weaker than Chloroform-Acetone interactions.
thus, we can conclude that for the given situation chloroform-chloroform interactions are weaker than chloroform-acetone interactions AND acetone-acetone interactions are weaker than chloroform-acetone interactions.
