Answer: hydrogen has 0.0504% and Fluorine has 0.950%
Explanation: H= 1.00794
F= 18.9984
1 X 1.00794+ 1 X 18.9984= 20.00778g/mol
H= 1.00794/20.00778= 0.0504%
F-18.9984/20.00778= 0.950%
Answer:
Maple syrup will have the higher temperature.
Explanation:
- Adding CaCl₂ to water and maple syrup will rise the temperature of both of them.
Specific heat of maple syrup = 2.01 J/g.°C
.
Specific heat of water = 4.18 J/g.°C.
- Which means that the energy needed to rise the temperature by 1.0 °C of 1.0 g of water (4.18 J) is twice as that needed to rise the temperature by 1.0 °C of 1.0 g of water (2.01 J).
- So, the temperature of maple syrup will be higher than that of water when CaCl₂ is added to both of them.

Answer:
hypertonic solution
Explanation:
Hypertonic solution -
It is the solution, with more amount of solute than the solvent , is known as hypertonic solution.
Now, is some substance is immersed in such solution , the substance gets shrinked , because , the solvent from the substance moves out of it and moves to the hypertonic solution.
Hence, the pickles gets shrinked up , as they put in a hypertonic solution.
