4. Chemical reactions

Chemical reactions generally take place

if the result is the formation of a more stable bond.

The reaction of CH₃OH with HCOOH produces

methyl ester of the formic acid

The oxidation product of 1-butanol produces

butyric acid

The oxidation of primary alcohols produces

aldehydes

The equilibrium constant of a chemical reaction depends on

temperature of reaction

The change in enthalpy of a given equation under constant pressure is

positive for endothermic reactions

Sulfur when burnt emits a flame of ____ color

blue

Substitution generally occurs

if one functional group in a compound is displaced by another

Phenols are formed by the oxidation of

arene

Oxidation is not

a decrease in the oxidation number

Homolytic fission takes place in

radical substitutions

Hess's law

is an application of the first law of thermodynamics in chemistry

Hess's law is used to calculate

the heat of reaction for processes that cannot be measured directly

Halogenation is essentially not a reaction of

polymerization

Guldberg-Waage's law

refers to the equilibrium of a chemical reaction

Esterification is

the reaction of organic acids with alcohols

Entropy expresses

the degree of disorder of a given system

Corrosion affects

all metals

Corrosion affects

iron

Carbon reacts with oxygen to form

CO

By removing a water molecule from (COOH)₂

oxalic acid anhydride is formed

By immersion of an iron nail into a solution of green rock

copper is reduced
