Answer:
v₂ = 48 mph
Explanation:
We know that,
Speed = distance/time
A German Shepherd takes 4 hours to cover a distance, if it travels at a speed of 36mph.
We need to find the speed to cover the same distance in 3 hours.
So, the new speed is 48 mph.
False, you pass a light through a mixture If the light bounces off the particles, you will see the light shine through and you have a colloid mixture

Depends if you have good taste.
It's revolution, and no, that would be a rotation.
Answer:
Amine have higher boiling points than hydrocarbons.
Explanation:
Primary, secondary and tertiary amines have higher boiling points than hydrocarbons because they can engage in intermolecular hydrogen bonding.
Amines has three classes
1. Primary amines
2. Secondary amines
3. Tertiary amines
All this classes of amines have higher boiling point than hydrocarbons due to C-N bond in them
This is because amines can engage in hydrogen bonding with water, amines of low molar mass are quite soluble in water.
Amines are having higher boiling points than hydrocarbons, as C-N bond in amines is more polar than a C-C bond in hydrocarbons. Due to the polar nature of amines, it forms intermolecular H-bonds and exists as associated molecules.
