Predict the products and write a balanced molecular equation for each reaction. If no reaction occurs, write 'NO REACTION.' c. liquid pentanol (C5H12O) and gaseous oxygen

검증된 단계별 안내
1
Identify the type of reaction: This is a combustion reaction where an organic compound reacts with oxygen.
Write the general form of a combustion reaction: C_xH_yO_z + O_2 \(\rightarrow\) CO_2 + H_2O.
Apply the general form to pentanol: C_5H_{12}O + O_2 \(\rightarrow\) CO_2 + H_2O.
Balance the carbon atoms: Ensure the number of carbon atoms on the reactant side equals the number on the product side by adjusting the coefficient of CO_2.
Balance the hydrogen and oxygen atoms: Adjust the coefficients of H_2O and O_2 to balance the hydrogen and oxygen atoms on both sides of the equation.

Combustion Reactions

Combustion reactions involve the reaction of a substance with oxygen, typically producing heat and light. In organic chemistry, these reactions often involve hydrocarbons or alcohols, resulting in carbon dioxide and water as products. Understanding the general form of combustion reactions is essential for predicting the products of the reaction between pentanol and oxygen.

Balancing Chemical Equations

Balancing chemical equations is a fundamental skill in chemistry that ensures the law of conservation of mass is upheld. This means that the number of atoms of each element must be the same on both sides of the equation. For the combustion of pentanol, one must account for all reactants and products to achieve a balanced equation, which reflects the stoichiometry of the reaction.

Oxidation States

Oxidation states (or oxidation numbers) indicate the degree of oxidation of an atom in a compound. In combustion reactions, the oxidation state of carbon in pentanol changes as it is oxidized to carbon dioxide. Understanding how to assign oxidation states helps in predicting the products of the reaction and determining whether a reaction will occur.

Hard water often contains dissolved Ca2+ and Mg2+ ions. One way to soften water is to add phosphates. The phosphate ion forms insoluble precipitates with calcium and magnesium ions, removing them from solution. A solution is 0.050 M in calcium chloride and 0.085 M in magnesium nitrate. What mass of sodium phosphate would you add to 1.5 L of this solution to completely eliminate the hard water ions? Assume complete reaction.
