اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Oxidation is a chemical process where an atom, molecule, or ion loses electrons, increasing in its oxidation state.
- k, Ea, T
- m, v, r
- a, b, c
- H, S, G
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The Arrhenius equation relates the rate constant (k), activation energy (Ea), and absolute temperature (T).
The equation is written as k = A * e^(-Ea/RT), where A is the frequency factor and R is the ideal gas constant
- Donates electrons
- Accepts electrons
- Gains protons
- Releases energy

Explanation
An oxidizing agent accepts electrons.
In a redox reaction, an oxidizing agent "oxidizes" another substance by causing it to lose electrons,
Meaning the oxidizing agent itself gains electrons.
- Covalent compounds
- Acids
- Ionic compounds
- Noble gases

اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The functional group present in aldehydes is the aldehyde group, which is represented as -CHO.
This group consists of a carbonyl group (C=O) where the carbon atom is bonded to at least one hydrogen atom.
- Alkynes
- Alcohols
- Phenols
- Carboxylic acids
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The functional group -COOH is the carboxyl group, which is a characteristic functional group of carboxylic acids.
Carboxylic acids are a class of organic compounds that contain this group, examples include:
- Formic acid (HCOOH)
- Acetic acid (CH3COOH)
- Citric acid (C6H8O7)
تمام تیزابوں میں عام عنصر _____ ہے؟
- Sulphur
- Oxygen
- Hydrogen
- None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
All acids contain hydrogen (H⁺) ions, which are responsible for their acidic properties.When dissolved in water, acids release H⁺ ions, making the solution acidic.
- HClO4
- HClO3
- HClO
- None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
HClO (hypochlorous acid) is the weakest acid among the given options.
The acidity of oxyacids of chlorine increases with the number of oxygen atoms bonded to chlorine.
- Liquids
- Gases
- Solids
- Plasma

Explanation
Kinetic Theory of Gases:
This theory explains that gases consist of a large number of tiny particles in constant, random motion.
The particles are far apart, move freely, and collide with each other and the container walls, which creates pressure.
