Explanation

A covalent bond forms when two non-metals share electrons.

This type of bond results in the formation of molecules like H₂O and CO₂.

Explanation

Assessment software is specifically designed to track and evaluate learner progress through quizzes, tests, and analytics.

It provides real-time feedback and performance data.

Explanation

Given reaction:

NO(g) + CO₂(g) ⇌ NO₂(g) + CO(g)

Initial moles:

NO = 4 mol

CO₂ = 0.9 mol

NO₂ = 0

CO = 0

At equilibrium:

CO₂ = 0.1 mol

→ So, change in CO₂ = 0.9 - 0.1 = 0.8 mol consumed

→ Therefore, 0.8 mol of NO also reacted

→ 0.8 mol each of NO₂ and CO formed

Equilibrium moles:

NO = 4 - 0.8 = 3.2 mol

CO₂ = 0.1 mol

NO₂ = 0.8 mol

CO = 0.8 mol

Equilibrium expression:

K = [NO2][CO]/[NO][CO2] = (0.8)(0.8)/(3.2)(0.1) = 0.64/0.32 = 0.2

Explanation

Aldol condensation requires at least one α-hydrogen (hydrogen on the carbon next to the carbonyl group).

Benzaldehyde and formaldehyde lack α-hydrogens, so they cannot undergo Aldol condensation.

Explanation

She directed us to keep quiet over there.

Imperative sentences in indirect speech use verbs like told, ordered, directed + to-infinitive.

"Here" changes to "there" in indirect speech.

Explanation

Promise: A commitment or assurance that one will do something or that something will happen.

The use of "shall" indicates a firm intention or vow about future support.

Explanation

The d subshell has 5 orbitals, each can hold 2 electrons, so total 10 electrons.

This is standard in electron configuration rules in chemistry.
