1.what causes a fire tornado to form ?

1 answer:

7 0

These start with a whirl of wind, often made visible by smoke, and may occur when intense rising heat and turbulent wind conditions combine to form whirling eddies of air. These eddies can contract a tornado-like vortex that sucks in debris and combustible gases.

Balance this reaction ch3oh+02 c02 h20

slega [8]

Answer:

2CH3OH + 3O2 --> 2CO2 + 4H2O

This is called Combustion of Methanol

Explanation:

Count the numbers of atoms on each sides and try to get the same amount of quantity on each sides, so you'll eventually get "balanced".

Watch this video: "How to Balance CH3OH + O2 = CO2+ H2O (Combustion of Methanol)"

Good luck with future work! Keep studying chemistry!

Answer:

alkenes

nucleophiles

electrophiles

syn

anti

syn and anti

Explanation:

Compounds that contain a carbon-carbon double bond are known as alkenes

Alkenes are electron rich; therefore, simple alkenes do not react with nucleophiles or bases, but will react with electrophiles or acids.

In the IUPAC system, an alkene is identified by the suffix -ene-

Addition reactions in which two parts Of a reagent are added to the same side of

a double bond are known as syn additions.

Addition reactions in which two parts of a reagent are added from opposite

sides of a double bond are called anti additions

Halogenation and halohydrin formation occur with syn and anti -additions.

Further explanations:

Compounds that contain a carbon-carbon single bond are known as alkanes. Compounds that contain a carbon-carbon double bond are known as alkenes. Compounds that contain a carbon-carbon triple bond are known as alkynes.

Nucleophiles are electron rich so they react with electron deficient centers while Electrophiles are electron deficient so they react with electron rich centers.

True or false: a mixture is always made up of a combination of elements

FromTheMoon [43]

A mixture has lots of different elements that are not necessarily bonded to each other, like sea water has lots of dirt, animals, and plant parts in it. Compared to a solution (strictly salt and water, which bond and ionize with each other).
