Capitolo 7, Problema 70c
Write a balanced equation for the reaction that occurs in each of the following cases: (c) Sodium reacts with oxygen.
Guida verificata passo dopo passo1
Identify the reactants: Sodium (Na) and Oxygen (O_2).
Determine the product: Sodium reacts with oxygen to form sodium oxide (Na_2O).
Write the unbalanced equation: Na + O_2 \(\rightarrow\) Na_2O.
Balance the equation by adjusting coefficients: Start by balancing the sodium atoms. Since there are 2 sodium atoms in Na_2O, place a coefficient of 2 in front of Na: 2Na + O_2 \(\rightarrow\) Na_2O.
Check the balance of oxygen atoms: There are 2 oxygen atoms on the reactant side and 1 on the product side. Place a coefficient of 2 in front of Na_2O to balance the oxygen: 4Na + O_2 \(\rightarrow\) 2Na_2O.

Balancing Chemical Equations
Balancing chemical equations involves ensuring that the number of atoms for each element is the same on both sides of the equation. This is based on the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. To balance an equation, coefficients are adjusted in front of the chemical formulas.

Balancing Chemical Equations
Sodium and Oxygen Reaction
When sodium (Na) reacts with oxygen (O2), it forms sodium oxide (Na2O). This reaction is an example of a combustion reaction where a metal reacts with a non-metal. Sodium is a highly reactive alkali metal, and it reacts vigorously with oxygen, often producing heat and light.

Types of Chemical Reactions
Chemical reactions can be classified into several types, including synthesis, decomposition, single replacement, and double replacement. The reaction between sodium and oxygen is a synthesis reaction, where two or more reactants combine to form a single product. Understanding these classifications helps in predicting the products and balancing the equations.
