The reaction of an amine with an acyl chloride produces an amide.

The main product is a quaternary ammonium salt when an amine reacts with an alkyl halide, as the amine can be further alkylated.

The reaction of ethene with bromine results in the formation of 1,2-dibromoethane.

The main product is ethane, formed by the hydrogenation of ethene.

Bromine reacts with phenol to form bromophenol, which is a substitution product.

Phenol reacts with bromine to form Bromophenol, which is a brominated derivative of phenol.

Phenol reacts with sodium hydroxide to form sodium phenoxide, which is a salt of phenol.

Propan-2-one (acetone) reacts with iodine in the presence of a base to form Iodoform.

Phenols react with bromine water to form brominated phenols, which are usually colorless or pale yellow.

Phenols react with sodium hydroxide to form sodium phenoxide, which is a salt of phenol.

Haloalkanes primarily undergo nucleophilic substitution reactions due to the presence of a good leaving group (halogen).

Citric acid is used as a preservative, flavoring agent, and cleaning agent.

The reaction of 1-bromobutane with sodium ethoxide leads to the formation of ethyl butyl ether through an SN2 mechanism.

The major product is But-2-ene due to the more stable double bond formed during elimination.

Molar mass of NaCl = 23 + 35.5 = 58.5 g/mol. Mass = moles x molar mass = 3 moles x 58.5 g/mol = 174 g.

The molar mass of NaCl is 58.5 g/mol. Therefore, 3 moles of NaCl weigh 3 x 58.5 g = 175.5 g.

Molar mass of NaOH = 40 g/mol; grams = moles × molar mass = (1 mole/L × 0.5 L) × 40 g/mol = 20 g

Molar mass of NaCl = 58.44 g/mol; mass = moles × molar mass = 3 moles × 58.44 g/mol = 175.32 g

Mass = moles × molar mass = (0.1 moles/L × 1 L) × 58.5 g/mol = 5.85 g.

Molar mass of NaOH = 40 g/mol. Mass = moles × molar mass = 0.5 moles × 40 g/mol = 20 g.

Mass percent = (mass of solute / total mass of solution) x 100 = (10 g / (10 g + 90 g)) x 100 = 10%

Area = 1/2 * base * height = 1/2 * 10 * x. Max area occurs when x = 10, giving Area = 50.

Area = 1/2 * base * height. Max area occurs when height is maximized, thus Area = 1/2 * 10 * 10 = 50.

Area = 1/2 * base * height = 5h. Max area occurs when h = 10, giving area = 50.

The maximum displacement in a mass-spring system is defined as the amplitude, which is given as 0.3 m.

The maximum height occurs at t = -b/(2a) = 1. h(1) = 64.

The maximum height occurs at t = -b/(2a) = -64/(2*-16) = 2. h(2) = -16(2^2) + 64(2) + 48 = 80.

The maximum number of bright fringes is given by the formula n = d/λ. Here, n = 0.1 mm / 500 nm = 200, which means 20 bright fringes can be observed on either side of the central maximum.

The maximum number of bright fringes depends on the wavelength and the slit separation, as it determines how many integer multiples of the wavelength fit within the observable range.

The d subshell can hold a maximum of 10 electrons.
