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%

The mass-energy equivalence formula is E = mc^2, which states that energy (E) is equal to mass (m) times the speed of light (c) squared.

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 = 1/2 * 10 * x. Max area occurs at x = 10, giving 50 m².

Area = 0.5 * base * height. Max area occurs when height is 10, giving Area = 0.5 * 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 displacement from the mean position in simple harmonic motion is called amplitude.

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.

The f-subshell can hold a maximum of 14 electrons.

The maximum number of electrons in a shell is given by the formula 2n². For n=3, it is 2(3)² = 18.

The maximum number of electrons in a shell is given by the formula 2n². For n=3, it is 2(3)² = 18.

Phosphorus can exhibit a maximum oxidation state of +5 in compounds like PCl5.

The maximum profit occurs at x = -b/(2a) = 10/2 = 5. P(5) = -5^2 + 10*5 - 16 = 9.

The vertex occurs at x = 2. f(2) = -2^2 + 4(2) + 1 = 5.

The vertex occurs at x = 3. f(3) = -9 + 18 - 8 = 1.

Maximum wavelength (λ) = hc/φ. λ = (1240 eV.nm) / 4.0 eV = 310 nm.
