Answer:
Thus the order of covalent character will be
DG < EG < DF < DE
Explanation:
The electronegativity decides the nature of bond formed between two atoms.
More the difference in electronegativity more the ionic character in the bond formed.
Let us check the electronegativity difference between the elements forming molecules
a) DE :
3.8-3.3 = 0.5
b) DG :
3.8-1.3 = 2.5
c) EG
3.3-1.3 = 2
d) DF
3.8-2.8 = 1.3
So the maximum ionic character will be in DG and minimum in DE
Thus the order of covalent character will be
DG < EG < DF < DE
The disease prevention methods are as follows:
- Influenza: Avoid close contact with sick people; Cover your mouth and nose, Clean your hands
- Salmonella: wash hands properly; keep food area clean; cook food properly
- Type 2 Diabetes : exercise regularly; reduce sugar intake; quit smoking
- HIV/AIDS: Avoid sharing of unsterilized sharp objects; avoid unprotected sex; screen blood before transfusion
- Heart disease: avoid trans fat; exercise regularly; avoid smoking
- Whooping cough: wear face masks; wash regularly; get vaccinated
<h3>What is the disease prevention?</h3>
Disease prevention refers to the steps taken to protect oneself from developing a particular disease.
The disease prevention methods for the given diseases is as follows:
- Influenza: Avoid close contact with sick people; Cover your mouth and nose, Clean your hands
- Salmonella: wash hands properly; keep food area clean; cook food properly
- Type 2 Diabetes : exercise regularly; reduce sugar intake; quit smoking
- HIV/AIDS: Avoid sharing of unsterilized sharp objects; avoid unprotected sex; screen blood before transfusion
- Heart disease: avoid trans fat; exercise regularly; avoid smoking
- Whooping cough: wear face masks; wash regularly; get vaccinated
In conclusion, disease prevention is the best policy in health care.

Answer:
-1151.5 J
Explanation:
Given that:
The supplies energy = 245 L
The energy used in the expansion of gas = Pressure ×ΔV (change in volume)
At standard conditions;
Pressure = 105 × 10³ Pa
energy used in the expansion = 105 × 10³ Pa × (38.6 - 25.3)L
= 1396.5 J
Thus, the change in the energy of gas = 245 - 1396.5 J
= -1151.5 J
Hence, we can conclude that the gas has lost its own energy in the process of expansion.
