Synthetic cathinone can be made in small amounts by creating a chemical reaction through the mixing of pseudoephedrine with regular household items.
<h3>What is cathinone?</h3>
Cathinone is an alkaloid drug obtained from a shrub plant (<em>Catha edulis</em>) and is equivalent to Akovaz (ephedrine).
The cathinone can also be artificially designed by using a pseudoephedrine medical drug.
Synthetic cathinone can be artificially produced in order to obtain this substance for medical use.

The answer is B. Suspension. Suspension mixtures are composed of two or more materials mixed together wherein the solute particles are usually larger than those found in a solution or colloid. In cases of solid-fluid suspension mixtures, the solid solute particles tend to settle at the bottom of the mixture after some time.
Explanation:
It is the heat required to change a gram of substance from a liquid to a gas.
Answer:
q = - 3.569KJ 0r 3.569KJ Liberated heat (signifying the change in heat is negative)
Explanation:
liberated heat implies that change in heat is negative , therefore
q = -m c ΔT
where, m = mass of the Silver = 249 g
c = specific heat capacity of Silver = 0.235 Jg^{-1} °C^{-1
ΔT = change in temperature = 87°C- 26 °C= 61°C
q = -m x c x ΔT
= - 249 x 0.235 x 61 = - 3569.415J rounded to -3569J
Changing to KJ becomes= -3569/1000= - 3.569 KJ
q = - 3.569KJ 0r 3.569KJ liberated heat.
