Answer:
<h2>Is broader than other models
</h2>
Explanation:
George Engel conceptualised the biospychosocial model in 1977. He suggested apart from the biological condition a persons medical condition is also dependent on social and psychological factors.
This model is used in cases of chronic pain and considers the pain as a psychophysiological behaviour pattern that cannot be categorised into social, psychological and biological perspective.
There are suggestions that physiotherapy should be integrated into psychological treatment to address the various components that comprises the experience of pain.
23. The correct answer would be a (AlPO4 + H2O).
This is an example of a neutralization reaction (an acid and a base react to form water and a salt).
24. a, combination reaction. There are two reactants and one product.
Answer:
Chemical properties
-It is not reverseable
-Change in energy is seen
-It is permanent change
-The change take place in both physical and chemical properties of matter
Physical properties
-The change takes place only in physical property of matter
-It can be reversed back
-It is temporary change
-Change in energy is not seen
Answer:
248 mL of 5% w/v boric acid solution should be used to obtain the solution needed.
Explanation:
We can calculate the volume of the 5% w/v boric acid solution needed to prepare the buffer solution 1.24% w/v using the following equation:

Where:
: is the concentration of the initial solution = 5% w/v
: is the concentration of the final solution = 1.24% w/v
: is the volume of the initial solution =?
: is the volume of the final solution = 1 L
Hence, the volume of the 5% solution is:

Therefore, 248 mL of 5% w/v boric acid solution should be used to obtain the solution needed.
I hope it helps you!
