testing different cognitive abilities, analytical skills, and subject-specific knowledge. In this essay, we will explore the nature of exams in business, law, and mathematics, their format, and how they evaluate students’ comprehension and
application of core concepts. We will also discuss the similarities and differences

double-displacement reaction - (ANSWER)is a reaction in which the positive and
negative ions of two ionic compounds exchange places to form two new
compounds.
Precipitate - (ANSWER)is an insoluble solid that emerges from a liquid solution.
The emergence of the insoluble solid from solution is called precipitation. Often
the precipitate emerges as a suspension. (Precipitates can form when two soluble
salts react in solution to form one or more insoluble products)
Energy Levels - (ANSWER)(also called electron shells) are fixed distances from the
nucleus of an atom where electrons may be found. As you go farther from the
nucleus, electrons at higher energy levels have more energy. Electrons in the
outermost energy level of an atom are called valence electrons
Marquis Test - (ANSWER)is commonly used for Ecstasy testing as MDMA turns
the precipitate purple black. Cobalt thiocyanate is used to test for cocaine. The
Cobalt is mixed with the questionable substance, then drowned in hydrochloric
acid, doused in chloroform, and shaken.
What is the relation between an atomic number and a mass number? -
(ANSWER)Atomic number is actually the number of protons in an atom while
mass number is the number of nucleons i. e, number of protons plus the number
of neutrons.

law, and mathematics, their format, and how they evaluate students’
comprehension and application of core concepts. We will also discuss the similarities and differences
Isotopes - (ANSWER)are members of a family of an element that all have the
same number of protons but different numbers of neutrons.
Chemical Synthesis - (ANSWER)the construction of complex chemical compounds
from simpler ones. It is the process by which many substances important to daily
life are obtained
Decomposition - (ANSWER)is a type of chemical reaction in which a single
compound breaks down into two or more elements or new compounds. These
reactions often involve an energy source such as heat, light, or electricity that
breaks apart the bonds of compounds
single-displacement reaction - (ANSWER)is a type of chemical reaction where an
element reacts with a compound and takes the place of another element in that
compound
Flame test - (ANSWER)analytical procedure used in chemistry to detect the
presence of certain elements, primarily metal ions, based on each element's
characteristic emission spectrum. The color of flames in general also depends on
temperature
Precipitation reaction - (ANSWER)In an aqueous solution, precipitation is the
process of transforming a dissolved substance into an insoluble solid from a
super-saturated solution. The solid formed is called the precipitate
