Let's write the balanced chemical reaction for this:
K₂CrO₄ + Pb(CH₃COO)₂ --> PbCrO₄ + 2 CH₃COOK
The products are lead(ii) chromate and potassium acetate. As you can notice, there is an exchange of ions involved for both reactants. This type ofreaction is called the <em>double-replacement reaction or also called metathesis</em>.
Answer: 19
Explanation:
In order to write the Potassium electron configuration we first need to know the number of electrons for the K atom (there are 19 electrons). When we write the configuration we'll put all 19 electrons in orbitals around the nucleus of the Potassium atom.
Answer:
The answer to your question is Cr₂O₃ + 3Mg ⇒ 2Cr + 3MgO
Explanation:
Data
Unbalanced chemical reaction
Cr₂O₃ + Mg ⇒ Cr + MgO
Reactants Elements Products
2 Cr 1
3 O 1
1 Mg 1
Balanced chemical reaction
Cr₂O₃ + 3Mg ⇒ 2Cr + 3MgO
Reactants Elements Products
2 Cr 2
3 O 3
3 Mg 3
Now the reaction is balanced
