Answer:
33km due south
Explanation:
Morant Bay is 33km south of Port Antonio;
Problem: displacement of Morant bay from Port Antonio;
Displacement is a vector quantity. It is the length of path between two position and the direction inclusive.
So, it has magnitude and must be specified with a direction.
A. lon charges are written as superscripts with the names of the
atoms.
B. Roman numerals are used instead of prefixes to indicate number.
C. Subscripts are used in the name to indicate number of atoms.
D. Ions combine in only one ratio.
Prefixes are not used to indicate the number of atoms when writing the chemical formula. The number of atoms are written as subscripts to their chemical symbols.
Chemical formula of a compound is used to identify a compound and distinguishes it from other compounds. A chemical formula is written from the chemical symbols of elements which constitute the compound.
The number of atoms of each element is written as the subscripts of the symbols for each atoms. For example,magnesium chloride contains one magnesium and two chlorine atoms thus, its formula is MgCl₂.
The subscripts for each atom in the formula of an ionic compound is the charge of the other atom into which it is bonded. Similarly, the formula of iron oxide containing 2 Fe and 3 O is written as Fe₂O₃.

Explanation:
The color of the emitted light depends on the energy. According to the arrangement of the electromagnetic spectrum, the color red has the lowest energy, the lowest frequency, and the largest wavelength
Which changes occur when O2(g) is added tothis system?
(1) The equilibrium shifts to the right and the concentration of PCl3(g) increases.
(2) The equilibrium shifts to the right and the concentration of PCl3(g) decreases.
(3) The equilibrium shifts to the left and the concentration of PCl3(g) increases.
(4) The equilibrium shifts to the left and the concentration of PCl3(g) decreases.
Given the data from the question, the correct answer to the question is:
The equilibrium shifts to the left and the concentration of PCl₃(g) decreases. (Option 4)
This is simply defined as a state in a chemical system where there is no observable change in the properties of the system with time.
A French scientist postulated a principle which helps us to understand a chemical system in equilibrium.
The principle states as follow:
Considering the question given above, we are concerned with O₂ (i.e concentration) being added to the reaction
2POCl₃(g) + energy <=> 2PCl₃(g) + O₂(g)
According to the principle given above, if more O₂ is added, then, PCl₃ and O₂ will react to produce more POCl₃. Thus, the equilibrium will shift to the left and also PCl₃ will reduce.
