Explanation

This reaction is endothermic in the forward direction.

According to Le Chatelier’s principle, increasing temperature favors the formation of products in an endothermic reaction, thus increasing the value of Kc.

Explanation

Tertiary (3°) alcohols dehydrate fastest because the formation of a stable carbocation is easier.

Secondary (2°) alcohols are slower, and primary (1°) alcohols are the slowest.

Explanation

Heat of combustion of CO: ΔH_comb = ΔH_f(CO₂) – ΔH_f(CO)

ΔH_comb = (-94.0) – (-26.4) = -94.0 + 26.4 = -67.6 Kcal

According to Hess’s Law, this is the heat released when 1 mole of CO burns to form CO₂.

Explanation

The charges of Proton, Electron, Neutron respectively are:

• Proton: Positive charge (+1)
• Electron: Negative charge (-1)
• Neutron: Neutral charge (0)

Explanation

The neutron is a neutral particle,

which is stable only in the confines of the nucleus of the atom.

Explanation

• Proton has a positive charge.
• Its charge is +1e.
• 1e = 1.602 x10^-19 C.
• Classification: Baryon
• Composition: 2 up quarks (u), 1 down quark (d)
• Statistics: Fermionic
• Family: Hadron
• Interactions: Gravity, electromagnetic, weak, strong
• Symbol p, p+, N+, 11H+
• Theorized: William Prout (1815)
• Discovered: observed as H+ by Eugen Goldstein (1886). Identified in other nuclei (and named) by Ernest Rutherford (1917–1920).

Explanation

Discoverer: Dmitri Mendeleev, a Russian chemist.

- Year: 1869

Explanation

• Mercury is a silvery-white liquid metal that was traditionally used in clinical thermometers due to its high coefficient of expansion.
• It allowing for accurate temperature measurements.

Explanation

The chemical formula of baking soda is NaHCO₃, which stands for sodium bicarbonate.

The chemical name of baking soda is sodium hydrogen carbonate or sodium bicarbonate (NaHCO3).

Sodium bicarbonate is non flammable

Baking soda is basic in nature.

Explanation

Magnesium Sulphate (Epsom salt) is a common laxative that helps relieve constipation by drawing water into the intestines.

It works by softening stool and promoting bowel movements when taken in proper dosage.
