Answer:

Sunlight. and maybe dead wood and sticks.

Explanation:

Lots of trees compete for the most sunlight. That's why if you go to a rain forest, there are different levels of ecosystems and sizes of trees.

Both beavers and otters compete for these sticks, if the beavers don't build strong enough, their home will collapse.

Before bonding, the atomâ€™s electrons spend most of their time ___________________ the nuclei of each atom.

Ket [755]

Answer:

Around.

Explanation:

A chemical formula helps scientists to show or illustrate the type and number of atoms present in a particular molecule or compound by using numerical subscript, ions and atomic symbol of a chemical element.

This ultimately implies that, a chemical formula is used to describe or denote the exact amount of atoms that make up a molecule or compound.

The type of bond which is formed when the atoms of a chemical element are sharing electrons is known as covalent bond. Thus, when two (2) atoms of a chemical element comes close together, the nucleus of one of the atom attracts the other atom's electrons.

However, before bonding takes place, the atom's electrons spend most of their time around the nuclei of each atom.

"benzyl ethyl ether reacts with concentrated aqueous hi to form two initial organic products (a and b). further reaction of prod

ahrayia [7]

Answer:

See below.

Step-by-step explanation:

Ethers react with HI at high temperature to produce an alky halide and an alcohol.

R-OR' + HI ⟶ R-I + H-OR'

Benzylic ethers react by an Sₙ1 mechanism by forming the stable benzyl cation.

PhCH₂-OR + HI ⟶ PhCH₂-O⁺(H)R + I⁻ Protonation of the ether
PhCH₂-O⁺(H)R ⟶ PhCH₂⁺ + HOR Sₙ1 ionization of oxonium ion
PhCH₂⁺ + I⁻ ⟶ PhCH₂-I Nucleophilic attack by I⁻

If there is excess HI, the alcohol formed in Step 2 is also converted to an alkyl iodide:

ROH +HI ⟶ R-I + H-OH

Thus, benzyl ethyl ether reacts to form benzyl iodide (a) and ethanol (b).

The ethanol reacts with excess HI in an Sₙ2 reaction to form ethyl iodide (c).
