The challenges I have encountered during assessment in terms of tourism skills is linking reliable, valid, and right learning assessment methods and tools to some of the course learning objectives. This may be due to my level of comprehension.
<h3>What is Tourism?</h3>
This is known to be a kind of social, cultural and economic situation that is based on the movement of people to countries or places outside their normal environment for different reasons.
The types of tourism are:
- Sustainable tourism
- Food tourism
- Experiential tourism and others.

Answer:
A positively charged benzenonium intermediate
Given 30.00 ml of 0.10 m acetic acid and 50.00 ml of 0.100 m koh, the pH of the solution is 12.40
<h3>What is the pH of a substance?</h3>
This is the measure of the acidity or the basicity of an aqueous or liquidsolution.
The details that are contained in this question are:
Mole of CH3COOH = 0.1 M
Volume of CH3COOH = 30 mL
Mole of KOH = 0.1 M
Volume of KOH = 50 mL
mol of (CH3COOH) = 0.1 Mole * 30 mL = 3 mol
mol of (KOH) = 0.1 Mole * 50 mL = 5 mol
From the solution above,
mol of CH3COOH = 3 mol
mol of KOH = 5 mol
3 mol of both substances is going to react
excess KOH remaining = 5 - 3 = 2 mmol
Volume of both Solutions
= 30 + 50 = 80 mL
OH⁻ = 2/80
= 0.025 M
use:
pOH = -log [OH-]
= -log (0.025)
pOH = 1.602
PH = 14 - pOH
= 14 - 1.60
= 12.40
The calculated pH is therefore 12.40
