Explanation:
According to Sigmund Freud, the part of the personality if not fully developed, a person will be more likely to commit a crime is the superego. The superego of one's person is the moral guide. This is the aspect of personality that when it is correctly developed, urges and desires of the id and the one's ego are being balanced. This is when a person rejects those that are not ethically right. When a person commits a crime, this person is more likely committed to his or her urges and desires without even thinking of what the consequences he or she will face.

Answer:
There are 0.301 moles of N2 gas in 6.75 liters of N2 gas.
Explanation:
Given,
Volume of N2 gas = 6.75 L
We know,
At STP,
Number of moles = 
[Here 22.4 liter is the molar volume of any gas at STP]
= 
= 
∴There are 0.301 moles of N2 gas in 6.75 liters of N2 gas.
Answer: 13.888g
Explanation:
CaCO3 —> CaO + CO2
From the equation above, 1mole of CaCO3 produces 1mole of CaO. Since the answer is to be expressed in grams, let us covert this mole to grams. This is illustrated below:
MM of CaCO3 = 40 +12 + (16x3) = 40 + 12 + 48 = 100g/mol
MM of CaO = 40 + 16 = 56g/mol
From the equation,
100g of CaCO3 produced 56g CaO
Therefore, 24.8g of CaCO3 will produce Xg of CaO i.e
Xg of CaO = (24.8 x 56) / 100 = 13.888g
Therefore, the theoretical yield of CaO is 13.888g
