What is a chemical test to distinguish between the liquids hexane and hexene

Hexane is alkane and hexene is alkene.

They can be distinguish by bromine test.

Hexane being a saturated hydrocarbon does not decolourizes Br2 in CCl4 and hexene being unsaturated ​ decolourizes Br2 in CCl4.

Reaction : CH3CH2CH2CH2CH2=CH2 + ​Br2 in CCl4 > CH3CH2CH2CH2CH2(Br)CH2Br ( colourless)

the tides are influenced by both the moon and the sun, it's easy to see that when the sun lines up with the moon and the earth, as during a new moon or full moon, the tidal effect is increased. these are known as spring tides, named not for the season, but for the fact that the water "springs" higher than normal. on the other hand, if the sun and the moon are 90 degrees apart in relation to an observer on earth as during the first quarter moon or third quarter moon, then high tides are not as high as they normally would be. this is because despite its greater distance, the sun's mass allows it to exert enough gravitational force on the oceans that it can negate some of the effects of the moon's pull. this phenomenon of lower high tides is called a neap tide. if you need more information on this topic visit moonconnection.com.

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
