How do an ionic bond and a covalent bond differ?

Chemistry

The formation of compound takes place by atom in order to complete their octet and attain stability. The atom combine with other atom either by sharing of electrons or transfer of electrons from one atom to other. The sharing of electrons results in the formation of covalent bond whereas transfer of electrons results in formation of ionic bond. The loss of electron from an atom results in formation of cation whereas gain of electron results in the formation of anion. The force of attraction between the two oppositely charged ions is electrostatic force of attarction.

Hence, an ionic bond is an attraction between opposite charged ions. a covalent bond is sharing of electrons between atoms.

The compound 1-butene is modeled here. What would need to happen for molecules of this compound to transform into polybutene? A.
kompoz [17]
In order to form polymers, we need to chain molecules together. This involves making bonds between them.

Shifting H’s around doesn’t accomplish anything.

Forming more double bonds will have the opposite result, as it would make the molecules more stable and less likely to react with each other.

Adding oxygen to the molecule no longer makes it polybutene. That would likely result in the formation of some sort of ether, as hey would react to form a C-O-C Bond.

The only answer left is A. In order to form polyalkenes, we have to break a double bond so that it’s available to form more covalent bonds.

Hope this helps

What is the net ionic equation for the reaction that occurs when aqueous copper(II) sulfate is added to excess 6-molar ammonia?a
Karolina [17]

Answer:

c. 2NH₃ + 2H₂O  + Cu²⁺ → Cu(OH)₂(s) + 2NH₄⁺

Explanation:

A net ionic equation is a chemical equation that list only the species that are involved in the reaction.

The reaction of ammonia with copper(II) sulfate CuSO₄ in water is:

2NH₃ + 2H₂O  + CuSO₄ → Cu(OH)₂(s) + 2NH₄⁺ + SO₄²⁻

In an ionic equation, salts are written as ions, that means CuSO₄ must be written as Cu²⁺ + SO₄²⁻. That is:

2NH₃ + 2H₂O  + Cu²⁺ +<u> SO₄²⁻</u> → Cu(OH)₂(s) + 2NH₄⁺ + <u>SO₄²⁻</u>

As in a net ionic equation you must list only the species involved in the reaction (The underlined species don't react), the net ionic equation is:

<em>c</em>. <em>2NH₃ + 2H₂O  + Cu²⁺ → Cu(OH)₂(s) + 2NH₄⁺</em>

<em></em>

I hope it helps!

Use the table to calculate ΔH°rnx for the following reaction
alexdok [17]

Answer:

The answer to your question is ΔH° rxn = -1343.9 kJ/mol

Explanation:

                       P₄O₆ (s)  +  2 O₂ (g)   ⇒  P₄O₁₀

ΔH°rxn = ?

Formula

ΔH°rxn = ∑H° products - ∑H° reactants

H° P₄O₆ = -1640.1 kJ/mol

H° O₂ = 0 kJ/mol

H° P₄O₁₀ = -2984 kJ/mol

-Substitution

ΔH° rxn = (-2984) - (-1640.1) - (0)

-Simplification

ΔH° rxn = -2984 + 1640.1

ΔH° rxn = -1343.9 kJ/mol

Claude Bernard first recognized _____.
storchak [24]

Answer : Option B) Plant stomata opening and closing to maintain homeostasis.

Explanation : Claude Bernand was a French Physiologist who first discovered about "homeostasis" which is defined as the controlled stability of the internal milieu, or internal environment, of cells and tissues in plants.

In plants stomatal opening and closing was done for maintaining homeostasis with the external and internal plant environment.
