Gain of Electrons
Loss of Electrons
Gain of Protons
Loss of Protons
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Oxidation is a chemical reaction involving the loss of electrons.
Oxidation:
When a substance loses electrons during a chemical reaction , it is said to be oxidized.
Reduction:
The opposite of oxidation is reduction, which is when a substance gains electrons.

اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Step 1: Find the pattern (differences)
6 − 2 = 4
12 − 6 = 6
20 − 12 = 8
30 − 20 = 10
42 − 30 = 12
The differences increase by 2 each time:
4, 6, 8, 10, 12, 14
Step 2: Find the next term
Next number = 42 + 14 = 56
انسولین جسم کے کس عضو سے تیار ہوتی ہے؟
Liver
Pancreas
Kidney
Brain
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Insulin is produced by the pancreas , which is an organ located behind the stomach.
The pancreas contains clusters of cells called the Islets of Langerhans, specifically the beta cells within these islets , which are responsible for producing insulin.
Insulin plays a crucial role in regulating blood sugar levels by facilitating the uptake of glucose into cells for energy production or storage.
When blood sugar levels rise after a meal, the pancreas releases insulin to help lower blood sugar levels by promoting the uptake of glucose into cells.

–1.6 × 10⁻¹⁹ C
–1.6 × 10⁻¹⁸ C
–1.6 × 10⁻²⁰ C
–3.2 × 10⁻¹⁹ C
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
- The elementary charge on a single electron is -1.6 × 10⁻¹⁹ coulombs.
- It’s a fundamental physical constant.
The charges of Proton, Electron, Neutron respectively are:
Proton: Positive charge (+1) Electron: Negative charge (-1) Neutron: Neutral charge (0)
Equal to rate constant
Greater than rate constant
Less than rate constant
None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
For a first-order reaction, rate r = k[A]. If [A] = 1 M , then rate = k × 1 = k , so the rate equals the rate constant .
Has constant pH
Resist change in its pH
Consists of a strong acid and a strong base
Contains salts of strong acids and strong bases
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
A buffer is a solution that resists change in its pH.
A buffer solution is composed of a weak acid and its conjugate base (or a weak base and its conjugate acid).
When a small amount of a strong acid or base is added to a buffer,
The added ions react with the components of the buffer to maintain a relatively constant pH.
The forward reaction increases
Both forward and reverse reaction remains unaffected
The reverse reaction decreases
The forward reaction decreases
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
If one mole of gaseous hydrogen is mixed with one mole of gaseous iodine in an empty container, then with time, the forward reaction decreases
Because as the reaction proceeds, the concentration of hydrogen and iodine decreases, leading to a slower rate of forward reaction, while the reverse reaction starts to increase until equilibrium is reached.
Axis of rotation
Plane of symmetry
Center of symmetry
Axis of Inversion
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The proper term for "X" is Plane of symmetry.
A plane of symmetry is an imaginary plane that divides a crystal into two halves, where each half is the mirror image of the other.
