Question

I need to add these 4 reactions together, but I'm not sure how to do so. Can I get a step-by-step on how to add them together?

a) Al(OH)₃(s) + 3H₂SO₄(aq) → Al₂(SO₄)₃(aq) + 6H₂O(l) + K₂SO₄(aq)
b) 2Al(s) + 2KOH(aq) + 6H₂O(l) → 2KAl(OH)₄(aq) + 3H₂(g)
c) 2KAl(OH)₄(aq) + H₂SO₄(aq) → 2Al(OH)₃(s) + 2H₂O(l) + K₂SO₄(aq)
d) Al₂(SO₄)₃(aq) + K₂SO₄(aq) + 24H₂O(l) → 2(KAl(SO₄)₂ * 12H₂O)(s)

Answer 1

To add chemical reactions, list them, cancel out repeating substances, then combine and balance the new equation, ensuring mass and charge conservation.

Step-by-step explanation:

To add together multiple chemical reactions, you should follow these steps:

1. Write down all the given reactions.
2. Cancel out substances that appear on both sides of the reactions when added together.
3. Combine the reactions by adding reactants to reactants and products to products.
4. Check to ensure all elements and charges are balanced in the final combined equation.

Here is an example:

• Take the reaction Al(OH)3(s) + 3HCl(aq) → AlCl3(aq) + 3H2O(l).
• If another reaction produces HCl that consumes AlCl3, such as: AlCl3(aq) + 3NaOH(aq) → Al(OH)3(s) + 3NaCl(aq),
• Combine them, canceling Al(OH)3 and AlCl3, to get: 3HCl(aq) + 3NaOH(aq) → 3NaCl(aq) + 3H2O(l).

Always double-check that the final equation is balanced with respect to both mass and charge.
