Explanation

In 1926, Schrödinger proposed the Quantum model of the atom using wave equations.

This model describes electrons as wave-like rather than fixed orbits.

Explanation

CaCO₃ → CaO + CO₂

This reaction absorbs heat to break calcium carbonate into calcium oxide and carbon dioxide.

It is a classic endothermic decomposition reaction, requiring continuous heating to proceed.

Explanation

Magnesium (Mg) electronic distribution = 2, 8, 2

The number of shells = 3 (so Period = 3)

The number of electrons in the outermost shell = 2 (so Group = 2)

Explanation

 Convection is the transfer of heat through the movement of a fluid, meaning it occurs in liquids and gases. 

Liquids: In liquids, warmer, less dense molecules rise, carrying heat with them. 

Gases: Similarly, in gases, hot molecules move more readily, transferring heat through the space

Explanation

6CO₂ + 6H₂O → C₆H₁₂O₆ + 7O₂

The given reaction is the photosynthesis equation, where carbon dioxide and water form glucose and oxygen.

To balance oxygen atoms, the reaction requires 6 oxygen molecules (O₂), which contain 12 oxygen atoms on both sides.

Explanation

The reaction at the anode is called oxidation

In electrochemical cells, the anode is where oxidation occurs, meaning the substance loses electrons.

This contrasts with the cathode, where reduction (gain of electrons) takes place. 

Explanation

Electrons involved in bond formation are in the valence shell, the outermost electron shell.

These electrons participate in chemical bonding between atoms.

Explanation

Explanation

Cobalt chloride paper is used to detect moisture; it turns from blue to pink in the presence of water vapor.

This change helps demonstrate transpiration as water evaporates from the leaf surface.

Explanation

Acids are not slippery; instead, they usually have a sour taste and can be corrosive.

Bases are the ones that feel slippery to touch.
