The substitution product that is supposed to be favoured. The product with retention of configuration is expected to predominate slightly because the leaving group blocks the nucleophile.
<h3>What is a substitution product?</h3>
A substitution product is a product that is gotten from a reaction in which a group of reactants is replaced by another group in the reaction.
Therefore, the substitution product is supposed to be favoured. The product with retention of configuration is expected to predominate slightly because the leaving group blocks the nucleophile.

#SPJ1
Given:
An experimental set-up where there are four test tubes containing different concentrations of hydrochloric acid, all at 25 degrees Celcius. All test tubes were added with 1 gram of Zn cube (at the same time).
The reaction which occurs at the fastest rate is the test tube where HCl concentration is greatest. The high concentration of HCl enhances the speed of the reaction.
Answer:
The mass of the given gold bar:<u> m = 1.8 × 10² g</u>
Explanation:
The Specific heat capacity (c) of a given substance is defined as the heat capacity (C) per unit mass (m) or the energy required (Q) to increase the temperature (ΔT) of the given substance per unit mass.
∴ <u>The specific heat capacity</u>: 
Given: The specific heat capacity of gold (Au) = 0.128 J/g°C
The increase in temperature: ΔT = 34.7°C - 30.0°C = 4.7°C
Heat energy: Q = 0.108 kJ = 0.108 × 1000 J = 108 J (∵ 1 kJ = 1000J)
Mass of the given gold bar: m = ?
<u>Therefore, the mass of the given gold bar</u>:
<u>Therefore, the mass of the given gold bar: m = 1.8 × 10² g</u>
Salt
Explanation:
Of the listed substances, salts would have the highest melting point.
Salts are ionic compounds that are bounded by strong electrostatic forces.
In an ionic compound, metal and non-metal bond together through electrostatic attraction of their ions.
- Melting point is a property induced but intermolecular forces.
- It is known that salts have very strong intermolecular forces between them.
- They exhibit ionic crystal lattice forces.
- They are the strongest forces.
- They are strong electrostatic attraction between oppositely charged ions arranged into a crystal lattice of ionic compounds.
