Explanation:
The country located at coordinates N 35°00' 00", latitude and E 33°00' 00" longitude is Cyprus and is surrounded by the Mediterranean Sea. The country I would like to go to would be the one located at coordinates N 41°89'01" E 12°49'22".
<h3>What is a geographic coordinate?</h3>
Geographic coordinates is a term that refers to a reference system that has the objective of identifying a point located on Earth using a system of numbers, letters or symbols.
The geographical coordinates take as reference points the Greenwich meridian (longitude 0°) and the line of the equator (latitude 0°). On the other hand, longitudes range from 0° to -180° or 180° and latitudes range from 0° to 90° or -90°.
According to the above, it can be inferred that the location of the coordinates N 35°00' 00", latitude and E 33°00' 00" longitude is the country of Cyprus surrounded by the Mediterranean Sea.

Answer:
pH = 12.2
Explanation:
Given data:
Mass of lime = 0.69 g
Volume = 1535 mL (1535 / 1000 = 1.535 L)
pH of solution = ?
Solution:
First of all we will determine the molarity.
Molarity = moles of solute / volume in litter
Number of moles = mass / molar mass
Number of moles = 0.69 g / 56.1 g/mol
Number of moles = 0.0123 mol
Molarity = moles of solute / volume in litter
Molarity = 0.0123 mol / 1.535 L
Molarity = 0.008 M
One mole of CaO neutralize two mole of OH⁻.
0.008 M×2 = 0.016 M
[OH⁻] = 0.016 M
pOH = -log [OH⁻]
pOH = [0.016]
pOH = 1.8
14 = pH +pOH
pH = 14 - pOH
pH = 14-1.8
pH = 12.2
solution:
The general form of the equation would be A = P x (1/2) ^ (t/h) where A = final amount, P = start amount, t = time (here in days) and h = half-life (has to be same units as t)
a) A = 192 x (1/2) ^ (15/5) = 192 x (1/2) ^3 = 192 x 1/8 = 24 mg
