In the reaction CuO(s) + CO2(g) → CuCO3(s), a. CO2 is the Lewis acid and CuCO3 is its conjugate base. b. O2– acts as a Lewis bas
adoni [48]

<u>Answer:</u> The correct answer is Option d.

<u>Explanation:</u>

According to Lewis acid-base concept:

The substance which is donating electron pair is considered as Lewis base and the substance which is accepting electron pair is considered as Lewis acid.

For the given chemical reaction:

CuO(s)+CO_2(g)\rightarrow CuCO_3(s)

CO_2 is accepting electron pair and is getting converted to CO_3^{2-}. Thus, it is considered as Lewis acid.

O^{2-} present in CuO is a Lewis base because it is donating electron pair.

Thus, the correct answer is Option d.

What does the term organic compound mean
Aleksandr [31]

Answer: carbon-containing compounds with covalent bonds

Explanation:

The term "organic compound" refers to the group of carbon-containing compounds such as glucose (C6H12O6), Propane (C3H8), ethyne (C2H2) etc, where the carbon atoms in them are covalently bounded to other atoms such as hydrogen, oxygen, phosphorus, nitrogen etc

Examples of organic compounds are ethanol (C2H5OH), ethylamine (C2H5NH2) etc.

Thus, organic compound are carbon-containing compounds with covalent bonds to other atoms.

if the Earth were to begin to enter another ice age, which of the following characteristics might help an animal survive?
Stolb23 [73]
Not sure but i think living things adapt to their environment.
Adaptations are traits giving an organism an advantage in a certain environment. And variations of individuals is important for a healthy species. So i think adaptation might be the right answer because animal will try to adapt the certain environment. I hope this answer will help you.

The C¬C bond in H₃C¬CF₃ (423 kJ/mol) stronger than that in H₃C¬CH₃ (376 kJ/mol) because of the strong negative inductive effect of fluorine atom

<h3>What is Inductive effect?</h3>

When an electron- withdrawing or an electron- releasing species is allow to introduce to a chain of atoms (generally a carbon chain), according to the species corresponding negative or positive charge is start relayed through the carbon chain by the atoms through which it attached. This makes a permanent dipole to arise in the molecule and is referred to as the inductive effect.

<h3>Types of Inductive effect</h3>

+ inductive effect

- inductive effect

<h3>What is negative inductive effect?</h3>

Whenever an electronegative atom, like halogen, is introduced to a chain of carbon atoms (generally carbon atoms), this results in unequal sharing of electrons which generates a positive charge which is transmitted through the chain.

This make a permanent dipole to arise in the molecule whereas the electronegative atom get a negative charge and the effect is known as the electron-withdrawing inductive effect, or the -I effect.

Thus, we concluded that the C¬C bond in H₃C¬CF₃ (423 kJ/mol) stronger than that in H₃C¬CH₃ (376 kJ/mol) because of the strong negative inductive effect of fluorine atom.
