Answer:
The melting point will be lowered and broadened.
Explanation:
The melting point of a substance is the temperature at which the substance changes state from solid to liquid. The incomplete drying of a sample may result in the presence of impurities. There is presence of solid sample in the solution that fails to dry. The solid sample is not fully crystallized from the solvent or any other liquid with which it can form a true solution. The presence of these impurities in a sample for example, the incomplete removal of a recrystallization solvent cause the melting point to both lowered and broadened.
Answer:
Newton's second law of motion is F = ma, or force is equal to mass times acceleration.
There will not be enough momentum from the first hill to cross another hill if he same or larger size because of the way potential energy and kinetic energy works it will not be able go as high as it could go on he fist hill.
Answer:
Visible light
Explanation:
Electromagnetic spectrum is the classification of the electromagnetic waves based on their frequency and wavelength. In order from the shortest to the longest wavelength, we have
Gamma rays
X-rays
Ultraviolet
Visible light
Infrared radiation
Microwaves
Radio waves
All these waves are invisible to human eye, except for the visible light part. Visible light is perceived as a different color by the human eye, depending on the wavelength of the light. In particular, we have:
Violet: 380 - 450 nm
Blue: 450 - 495 nm
Green: 495 - 570 nm
Yellow: 570 nm - 590 nm
Orange: 590 nm - 620 nm
Red: 620 nm - 750 nm
