Detailed explanation-1: -Oxygen reacts with silicon and carbon to form silicon dioxide and carbon dioxide. Carbon is also able to react with oxygen to form carbon monoxide which is slightly acidic.
Detailed explanation-2: -Oxygen is reactive and will form oxides with all other elements except the noble gases helium, neon, argon and krypton.
Detailed explanation-3: -Calcium reacts with oxygen to form calcium oxide. It is having high melting point and is soluble in water.
Detailed explanation-4: -The hydrogen and oxygen atoms that combine to form water molecules are bound together by covalent bonds. The electron from the hydrogen splits its time between the incomplete outer shell of the hydrogen atoms and the incomplete outer shell of the oxygen atoms.
Detailed explanation-5: -Carbon combines with oxygen to form Carbon dioxide, CO2 and carbon monoxide, CO.
