Balance the following equations. (c) NH 4 ClO 4 + Al → Al 2 O 3 + N 2 + Cl 2 + H 2 O

Hey everyone. We're asked to balance the given chemical reaction first. Let's go ahead and count the number of atoms we have on both sides. Starting off with our react inside. We have one of nickel, one of hydrogen, one of nitrogen And three of oxygen. Looking at our product side, we have one of nickel as well, two of hydrogen, three of nitrogen and nine of oxygen only. Our nickel is balanced out. Let's first start off by balancing out our hydrogen. So if we add a coefficient of two prior to our nitric acid, we then are able to change our hydrogen into two, our nitrogen into two as well, And our oxygen's into six. Since we still need to change our nitrogen and oxygen's, this means we have to change The coefficient that we just inputted, which is R two. So instead of two, we can then go ahead and input a four prior to our nitric acid. And when we do that, we change our hydrogen into four, Our nitrogen into four as well. And our oxygen's into 12. Now that we've done this, we can adjust accordingly and look at our product side, we can add a coefficient of two prior to our water. And when we do this, we end up with four of hydrogen and our oxygen's changed from 9 to 10. Lastly, all we need to do is fix our nitrogen and our oxygen's and we can do that by fixing our nitrogen dioxide. So when we add a two prior to nitrogen dioxide, We end up with four of nitrogen And 12 of oxygen. So our balanced chemical reaction is going to be as such. So I hope this made sense and let us know if you have any questions.

Problem 42c

Chapter 3, Problem 42c

Balance the following equations. (c) NH₄ClO₄ + Al → Al₂O₃ + N₂ + Cl₂ + H₂O

Verified step by step guidance

Write down the unbalanced chemical equation: NH_4ClO_4 + Al → Al_2O_3 + N_2 + Cl_2 + H_2O.

List the number of each type of atom on both sides of the equation to identify which elements are unbalanced.

Start by balancing the metals: Balance the aluminum (Al) atoms by ensuring the number of Al atoms on the reactant side equals the number on the product side.

Balance the non-metals: Balance the nitrogen (N), chlorine (Cl), and oxygen (O) atoms by adjusting coefficients as needed.

Finally, balance the hydrogen (H) atoms by adjusting the coefficient of H_2O, and check that all elements are balanced.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Balancing Chemical Equations

Balancing chemical equations involves ensuring that the number of atoms of each element is the same on both sides of the equation. This is achieved by adjusting the coefficients in front of the chemical formulas. The law of conservation of mass dictates that matter cannot be created or destroyed in a chemical reaction, thus requiring balanced equations.

Stoichiometry

Stoichiometry is the quantitative relationship between reactants and products in a chemical reaction. It allows chemists to calculate the amounts of substances consumed and produced in a reaction based on balanced equations. Understanding stoichiometry is essential for predicting yields and determining the proportions of reactants needed.

Types of Chemical Reactions

Chemical reactions can be classified into several types, including synthesis, decomposition, single replacement, and double replacement reactions. Recognizing the type of reaction can help in predicting the products and understanding the underlying mechanisms. In the given equation, the presence of aluminum and ammonium perchlorate suggests a redox reaction, where oxidation and reduction processes occur.
