Balance the following equations: (c) Al(OH) 3 (s) + H 2 SO 4 (l) → Al 2 (SO 4 ) 3 (s) + H 2 O(l)

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 11c

Chapter 3, Problem 11c

Balance the following equations: (c) Al(OH)₃(s) + H₂SO₄(l) → Al₂(SO₄)₃(s) + H₂O(l)

Verified step by step guidance

Identify the number of each type of atom on both sides of the equation.

Start by balancing the aluminum (Al) atoms. There are 2 Al atoms in Al2(SO4)3, so you need 2 Al(OH)3 on the reactant side.

Next, balance the sulfate (SO4) groups. There are 3 SO4 groups in Al2(SO4)3, so you need 3 H2SO4 on the reactant side.

Balance the hydrogen (H) atoms. Count the H atoms from both Al(OH)3 and H2SO4 on the reactant side and ensure they match the number of H atoms in H2O on the product side.

Finally, balance the oxygen (O) atoms. Check that the total number of O atoms on both sides of the equation is equal.

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 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. Coefficients are used to adjust the quantities of reactants and products to achieve balance.

Types of Chemical Reactions

Understanding the types of chemical reactions, such as double displacement, is crucial for balancing equations. In a double displacement reaction, two compounds exchange ions to form new compounds. Recognizing the reactants and products in the given equation helps in predicting the correct products and their states.

States of Matter in Reactions

The states of matter (solid, liquid, gas, aqueous) are important in chemical equations as they provide information about the physical state of the reactants and products. In the given equation, Al(OH)3 is a solid, H2SO4 is a liquid, and the products include a solid and a liquid. This information can influence the reaction conditions and the balancing process.
