Answer:
286 minutes
Explanation:
Given the content of fat in a meal= 53g
the content of protien in a meal= 38g
the content of carbohydrate in a meal= 152g
Also given that fuel value of protien = 17 KJ/g
the fuel value of fat = 38 KJ/g
the fuel value of carbohydrate = 17 KJ/g
Now to burn all the molecules the energy recquired is content of molecule times the fuel value.
the energy recquired to burn fat =
the energy recquired to burn protien =
the energy recquired to burn carbohydrate =
The total energy=2014+646+2584=5244KJ
The energy spent on swimming is 1100KJ/hour
for 1 hour 1100 KJ are spent
to spend 5244 KJ of energy the time taken is = =4.76hours
We know 1 hour=60 minutes
The total time =
Answer: The precipitate formed is
Explanation:
A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid or precipitated form are represented by (s) after their chemical formulas.
A double displacement reaction in which one of the product is formed as a solid is called as precipitation reaction.
The balanced chemical equation is:
