The reason for the solubility of some covalent compound as compared to other in water is to be determined. Concept introduction: A solution is a combination of two parts: solute and solvent. A solute is the substance that is present in small quantity and solvent is the substance in which solute is dissolved. When water acts as a solvent then it is known as an aqueous solution. A covalent compound is a formed by sharing of electrons between the non-metals. A covalent compound can be classified into two types: polar covalent compounds and nonpolar covalent compounds. When there is an electronegativity difference between the atoms then it is known as polar covalent compound and when there is no electronegativity difference between the atoms then it is known as a nonpolar covalent compound.

1) Suppose 0.1 kg ice at 0°C (273K) is in 0.5kg water at 20°C (293K). What is the change in entropy of the ice as it melts at 0°?
To produce the original "water gas" mixture, carbon (in a combustible form known as coke) is reacted with steam: 131.4 kJ + H20(g) + C(s) → CO(g) + H2(g) From this information and the equations in the previous problem, calculate the enthalpy for the combustion or carbon to form carbon dioxide.
kindly show me how to solve this long problem. Thanks
