In order to separate iron filing mixed in sugar and sand, one must use magnet. This exercise aims to explain the electricity and magnetism. In this exercise, the iron fillings will move to the area where the magnet is situated, this is the magnetic field where the area has magnetic forces. These forces, represented in magnetic lines, do not overlap with each other and are stronger when in they are near the north and south poles of the magnet. Opposite poles attract, like poles repel.

Place the following steps used to separate sand, iron filings, andsugar in order. Pour the sand and saltwater mixture into a filter toseparate the sand. Leave the saltwater solution out in the sun to evaporate the water. Pour the remainder of the mixture into a beaker with warm water.

So what you would do is go through and add 3 teaspoons(tsp) 6 times because of the 6 tablespoons(tbsp). which will give you an answer of 18. another way is to multiply 3x6=18.

Answer from: Quest

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.

The human eye contains a molecule called 11-cis-retinal that changes shape when struck with light of sufficient energy. the change in shape triggers a series of events that results in an electrical signal being sent to the brain that results in vision. the minimum energy required to change the conformation of 11-cis-retinal within the eye is about 164 kj/mol.
