I'm pretty sure it would be a chemical reaction.

Answer: This reaction is a type of synthesis reaction.

Explanation: When iron reacts with oxygen which is available in air, it leads to the formation of a reddish-brown compound known as rust.

This reaction is considered as oxidation-reduction reaction because iron is getting oxidized to Fe^{2+} and oxygen is getting reduced to oxide ion.

Equation of the rust follows:

4Fe(s)+3O_2(g)+nH_2O(l)\rightarrow 2Fe_2O_3.nH_2O

Synthesis reactions are defined as the reactions in which two or more than two reactants combine together to form a single product which can be a molecule or a compound.

The rusting of iron is also considered as a synthesis reaction because iron and oxygen are combining together to form a single compound known as rust.

Both these reactions are a type of Chemical reactions.

Which statements about allosteric enzymes are true?
Ainat [17]

Answer:

1,2 and 4 are correct

Explanation:

Enzymes that show cooperativity are defined as Allosteric enzymes. This cooperativity is of several types.

1) homotropic/homoallestery - positive cooperation

2) heterotropic/heteroallestery - negative cooperation

Activity of allosteric enzymes is regulated by other molecules (effector molecules)

Hence, statement 1 and 2 are correct.

Binding curve of allosteric enzymes:

For cooperative binding, binding curve is Sigmoidal curve

For non cooperative binding, binding curve is Hyperboilc curve.

Hence, statement 3 is wrong.

Allosteric enzymes have multiple active sites.

Allosteric enzymes are often multi sub unit proteins.

Hence, statement 4 is correct.

Construct a three-step synthesis of trans-2-pentene from acetylene by dragging the appropriate formulas into the bins. Note that
Aleks [24]

Answer:

The three-step synthesis of trans-2-pentene from acetylene is as follows.

<u>Step -1:</u> Formation of higher order terminal alkyne on reaction with sodium acetylides with haloalkanes.

<u>Step -2:</u> Formation terminal alkyne to nonterminal alkynes.

<u>Step -3:</u> Formation of trans-pent - 2-pent-ene by reduction.

Explanation:

Synthesis of trans-pent-2-yne from ethyne takes place is mainly a three step synthesis which involves formation of higher order terminal alkyne on reaction with sodium acetylides with haloalkane. Second step involves the further alkylation of terminal alkynes to higher order nonterminal alkynes and the third step involves the formation of trans-2-ene by dissolving reduction method.

The chemical reaction of each step of chemical reactions is as follows.
