1-bromopropane reacts with sodium hydroxide in ethanol to form 1-Propanol via nucleophilic substitution.

The reaction produces Ethylamine as ammonia acts as a nucleophile and replaces the bromine atom.

The reaction between an amine and an acid produces a salt, as the amine acts as a base and accepts a proton from the acid.

The reaction produces Diphenylmethanol when benzaldehyde reacts with phenylmagnesium bromide.

In acidic medium, Cr2O7^2- is reduced to Cr^3+.

The product of the roots is given by c/a = 9/3 = 3.

The product of the roots is c/a = 6/1 = 6.

The product of the roots is given by c/a = 6/1 = 6.

The product of the roots is given by c/a = 24/1 = 24.

proj_B(A) = (A · B / |B|^2)B = ((3*1 + 4*1) / (1^2 + 1^2))(i + j) = (7/2)(i + j) = 3.5.

Area = πr²; 154 = 22/7 * r²; r² = 154 * 7/22 = 49; r = 7 units.

Radius is half of the diameter. Therefore, radius = 14 cm / 2 = 7 cm.

For a first-order reaction, k = 0.693 / t₁/₂. Here, t₁/₂ = 10 min, so k = 0.693 / 10 = 0.0693 min⁻¹.

The rate law for a reaction is determined by the order with respect to each reactant. For a first order with respect to A and second order with respect to B, the rate law is Rate = k[A][B]^2.

For a second order reaction with respect to A, the rate law is expressed as Rate = k[A]^2.

The rate law is determined by the order of the reaction with respect to each reactant. For first order in A and second order in B, the rate law is Rate = k[A][B]^2.

The real part of the complex number 4 + 5i is 4.

The standard reduction potential for 2H⁺ + 2e⁻ → H₂ is 0.00 V.

The relationship is ΔG = -nFE, where n is the number of moles of electrons transferred.

The period T is the reciprocal of frequency f, given by T = 1/f.

According to the Arrhenius equation, the rate of reaction increases exponentially with temperature.

(15 + 5) = 20, so 20 × 2 = 40.

15 ÷ 3 = 5, then 5 × 4 = 20.

Methane (CH4) has a tetrahedral shape due to the four pairs of bonding electrons around the central carbon atom.

The s orbital has a spherical shape.

The SI unit of electric charge is Coulomb (C).

Acetone (CH3COCH3) is the simplest ketone.

Slope = (6-2)/(3-1) = 4/2 = 2.

The slope of the line is 7/2. The slope of the perpendicular line is the negative reciprocal, which is -2/7.

f'(x) = 2x + 2. At x = 1, f'(1) = 2(1) + 2 = 4.
