Answer:

AlI_3

Explanation:

Combination reactions are the reactions in which two or more atoms/ molecules combine to give a single product.

Aluminum metal combines with iodine to given aluminium iodide.

Aluminium has a valency of 3 and iodine has valency of 1, so the formula is AlI_3

The reaction is shown below as:

Al_{(s)}+I_2_{(s)}\rightarrow AlI_3_{(s)}

For each of the following substituents, indicate whether it withdraws electrons inductively, donates electrons by hyperconjugati
aleksandrvk [35]

Answer:

Br- Withdraws electrons inductively

       Donates electrons by resonance

CH2CH3 - Donates electrons by hyperconjugation

NHCH3- Withdraws electrons inductively

              Donates electrons by resonance

OCH3 -  Withdraws electrons inductively

              Donates electrons by resonance

+N(CH3)3 - Withdraws electrons inductively

                   

Explanation:

A chemical moiety may withdraw or donate electrons by resonance or inductive effect.

Halogens are electronegative elements hence they withdraw electrons by inductive effect. However, they also contain lone pairs so the can donate electrons by resonance.

Alkyl groups donate electrons by hyperconjugation involving hydrogen atoms.

-NHCH3  and contain species that have lone pair of electrons which can be donated by resonance. Also, the nitrogen and oxygen atoms are very electron withdrawing making the carbon atom to have a -I inductive effect.

+N(CH3)3 have no lone pair and is strongly electron withdrawing by inductive effects.

Which substance used during photosynthesis does a plant take in from the soil?
Simora [160]

Answer:

the answer is water

Explanation:

During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
