Answer:
One of the post school destination challenges are the disability of the students to cope with the vast syllabus of the subjects.
Explanation:
The challenge of adapting with the new system of education is a great challenge to may students in this society.
The post school destination programs offers the students a great place to learn more to apply their skills in their specific fields.
When students overcome this challenge, they will be able to learn new subjects and apply the same in their practical life which is considered as a great opportunity.

Answer:
Volume is 0.00233mL
Explanation:
Hello,
The density of a substance is the mass per unit volume of that substance.
Density = mass / volume
To solve this question, we need to get our data first.
Data;
Density = 19.3g/mL
Mass = 45mg = 0.045g
Volume = ?
Density = mass / volume
Density (ρ) = mass (m) / volume (v)
ρ = m / v
v = m / ρ
v = 0.045 / 19.3
v = 0.00233mL
The volume of the substance is 0.00233mL
The correct option is ARGON.
To quickly find out the element that is been described by the electronic configuration, write down and add together all the index figures in the electronic configuration. The index figures in the above electronic configuration are 2, 2, 6, 2 and 6. If you add all these figures together, you will get 18 and the element that has the atomic number of 18 is argon.
Answer : The correct option is, (B) bimolecular
Explanation :
Molecularity : It is defined as the total number of reactant molecules taking part in the balanced equation of a reaction. It is a theoretical concept.
The given chemical reaction are,
Step (1) :
Step (2) :
Step (3) :
The number of reactants molecules taking part in the balanced equation of a reaction 2 are, .
In this reaction, 1 'I' molecules reacts with the 1 molecule.
Total number of reactant molecule = 1 + 1 = 2
The molecularity of the reaction is 2 that means, the elementary reaction is bimolecular.
Hence, the correct option is, (B) bimolecular
