Boron is primarily used in the production of glass and ceramics.

Boron is primarily used in the production of glass and ceramics.

Calcium carbonate is commonly used in antacids to neutralize stomach acid.

Glycerol is commonly used as a sweetener in food products due to its sweet taste and ability to retain moisture.

Polyethylene is primarily used in packaging due to its flexibility and durability.

Polystyrene is widely used in packaging materials due to its lightweight and cushioning properties.

Sulfuric acid is primarily used in the production of fertilizers.

Sulfuric acid is primarily used as battery acid in lead-acid batteries.

The principal quantum number (n) indicates the energy level; for the third energy level, n = 3.

Sodium has an atomic number of 11, and its outermost electron is in the 3rd shell, so n=3.

Sodium has the electronic configuration of 1s² 2s² 2p⁶ 3s¹, so the principal quantum number for the outermost electrons is 3.

Chlorine has an atomic number of 17, and its outermost electrons are in the n=3 shell.

The principle behind a thermos flask is insulation, which minimizes heat transfer.

A hydraulic lift operates based on Pascal's law, which states that pressure applied to a confined fluid is transmitted undiminished in all directions.

Bernoulli's Principle states that an increase in the velocity of a fluid occurs simultaneously with a decrease in pressure.

Number of kings = 4. Probability = 4/52 = 1/13.

Number of queens = 4. Probability = 4/52 = 1/13.

There are 2 outcomes: heads or tails. Probability of heads = 1/2.

The probability of obtaining a homozygous recessive offspring (aa) from a cross between two heterozygous parents (Aa x Aa) is 25%.

Possible combinations for sum of 7 = (1,6), (2,5), (3,4), (4,3), (5,2), (6,1) = 6. Total outcomes = 36. Probability = 6/36 = 1/6.

Replication is the process by which DNA is copied to produce two identical DNA molecules.

The emission of an alpha particle from a nucleus is known as alpha decay.

The process of a solid turning directly into a gas is called sublimation.

Beta decay is the process in which a neutron is converted into a proton, emitting an electron and an antineutrino.

The process of forming a polymer from monomers is called polymerization.

The process of fusion of male and female gametes is called fertilization.

The process of heat transfer through the movement of fluids is called convection.

1-bromopropane reacts with sodium hydroxide in ethanol to form 1-propanol through a nucleophilic substitution reaction.

9 × 6 = 54.

9 × 7 = 63.
