Answer:
32.4 K
Explanation:
Initial pressure P1= 50.0mmHg
Initial temperature T1= 540K
Final temperature T2=????
Final pressure P2= 3 mmHg
From
P1/T1= P2/T2
P1T2= P2T1
T2= P2T1/P1
T2= 3×540/50.0= 1620/50.0
T2= 32.4 K
Answer: m= 0.69 m or mol/kg
Explanation: Molality is expressed as moles per unit kilograms of solvent or m= n / kg
First convert 25.0 g NaCl to moles
25.0 g NaCl x 1 mole NaCl / 58 g NaCl
= 0.43 moles NaCl
Next convert 625 g H2O to kilograms
625 g H2O x 1 kg / 1000 g H2O
= 0.625 kg H2O
Substitute the values in the formula
m = n / kg
= 0.43 mole NaCl / 0.625 kg
= 0.69 m or mole / kg
Answer:
D) saturated fat
Explanation:
Saturated fat -
It is a form of fat , where saturation is present , i.e. , presence of single bonds , it is a type of very unhealthy fat .
Butter , red meat , coconut oils and palm are rich in saturated fat , and are mostly in solid state at room temperature .
These fats often tends to be collected in the walls of arteries , and , can act as a restriction to the flow of blood .
Hence , the correct option for the given information of the question is saturated fat .
