The phospholipid head is hydrophilic which means it has an affinity for water. And it is true.
<h3>What is phospholipid , its component and how come it is hydrophilic?</h3>
- Phospholipid contains of a head and a tail , the head part of phospholipid consist of phosphate group and for further clarification the tail part of phospholipid consist of fatty acids.
- As we know already phosphate group that is OH- is negatively charged which clearly which its head is going to be polar .
- Since its polar , its hydrophilic. There is a specific function performed by phosphate group that cannot be filled by other compound present simultaneously.
- Phosphate group grabs a role to provide space to other compounds too.

Answer: The heat required to melt 25.0 g of ice at 
is 8350 Joules
Explanation:
Heat of Fusion tells us how much energy is needed to convert 1g of a solid to a liquid at the same temperature.
Q = Heat absorbed = ?
m = mass of ice = 25.0 g
L = Latent heat of fusion of ice = 334 J/g
Putting in the values, we get:
Thus heat required to melt 25.0 g of ice at is 8350 Joules
Answer : The volume for 6.0m HCl solution required = 62.5 ml
Solution : Given,
Initial concentration of HCl solution = 6.0m
Final concentration of HCl solution = 1.5m
Final volume of HCl solution = 250 ml
Initial volume of HCl solution = ?
Formula used for dilution is,
where,
= initial concentration
= final concentration
= initial volume
= final volume
Now put all the given values in above formula, we get the initial volume of HCl solution.
= 62.5 ml
Therefore, the volume for 6.0m HCl solution required = 62.5 ml
Answer:
C3F7
'Tri' means 3
Tricarbon means 3 carbon
"Hepta" means 7
Fluoridez molecular formula is "F"
hence F7
