Answer:
Which best describes the geologic time scale? It explains why events happen throughout Earth’s history. It presents the correct sequence of events in Earth’s history. It is used to determine the absolute dates in years for different periods.
It changes from a liquid from to a solid.
I hope this helps!
Chemical reaction is given as :
Here, 2 moles of water gives 2 moles of hydrogen and one mole of oxygen.
Mass of hydrogen = 28.0 g (given)
Mass of oxygen = 224.0 g (given)
Number of moles = 
Thus, number of moles of hydrogen = 
= 14 moles of hydrogen
Number of moles of oxygen= 
= 7 moles of oxygen
Now, to find the amount of water:
= 252 g of water.
Thus, amount of water is 252 g (involved in the process).
Answer: All of the statements (A-D) are false
Explanation: All of the given statements are wrong as Hydrogen bonds are weaker than the ionic and the covalent bonds.
Liquid water is more dense than the solid water.
When heat or temperature is provided to the system of the ice, not only covalent bonds are broken but also hydrogen bonds also get broke.
Energy must not be given off in order to break down the crytsal lattice of ice to a liquid. Infact in changing the phase of the water, energy is released.
