Chapter 22, Problem 71d
Write chemical equations for the reaction of calcium with the following substances, making sure that the numbers and kinds of atoms are the same on both sides of the equations. If no reaction occurs, write N.R.
(d) O2
Verified step by step guidance1
Identify the reactants: Calcium (Ca) and Oxygen (O_2).
Determine the type of reaction: This is a synthesis reaction where a metal reacts with a non-metal to form an ionic compound.
Predict the product: Calcium will react with oxygen to form calcium oxide (CaO).
Write the unbalanced chemical equation: Ca + O_2 \(\rightarrow\) CaO.
Balance the chemical equation: Ensure the number of atoms of each element is the same on both sides. The balanced equation is 2Ca + O_2 \(\rightarrow\) 2CaO.
Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Chemical Reactions
A chemical reaction involves the transformation of reactants into products, characterized by the breaking and forming of chemical bonds. In a balanced chemical equation, the number of atoms for each element must be the same on both sides, adhering to the law of conservation of mass. Understanding the types of reactions, such as synthesis, decomposition, and combustion, is crucial for predicting the products formed.

Chemical Properties
Balancing Chemical Equations
Balancing chemical equations is the process of ensuring that the number of atoms of each element is equal on both sides of the equation. This is achieved by adjusting the coefficients in front of the chemical formulas. A balanced equation reflects the conservation of mass and allows for accurate stoichiometric calculations, which are essential for determining the amounts of reactants and products involved in a reaction.

Reactivity of Elements
The reactivity of elements, particularly metals like calcium, determines how they interact with other substances. Calcium is an alkaline earth metal that readily reacts with oxygen to form calcium oxide (CaO). Understanding the reactivity series helps predict whether a reaction will occur and what products will be formed, as some elements are more reactive than others and can displace them in reactions.
