Answer:
=1.36kg
Explanation:
First heat is absorbed to melt the ice- latent heat of fusion of ice then heat is absorbed to raise the temperature to 373K
The specific heat capacity of water is 4.187kJ/kg/K while the latent heat of fusion of ice is 2230kJ/kg/K.
Letting the mass of the ice to be =x
x×2230kJ/kg/K + x×4.187kJ/kg/K×100K= 3600kJ
2230x+418.7x=3600
2647.8x=3600
x=1.36 kg
Hydrogen bonds are not like covalent bonds. They are nowhere near as strong and you can't think of them in terms of a definite number like a valence. Polar molecules interact with each other and hydrogen bonds are an example of this where the interaction is especially strong. In your example you could represent it like this:
<span>H2C=O---------H-OH </span>
<span>But you should remember that the H2O molecule will be exchanging constantly with others in the solvation shell of the formaldehyde molecule and these in turn will be exchanging with other H2O molecules in the bulk solution. </span>
<span>Formaldehyde in aqueous solution is in equilibrium with its hydrate. </span>
<span>H2C=O + H2O <-----------------> H2C(OH)2</span>
