Answer:
Explanation:
It is called a single replacement. K is one of the few chemicals that can force Aluminum to take on electrons. The balanced equation is
AIBr3 +3K → 3KBr + AI
Answer is: the maximum concentration of Pb²⁺ is 6.8·10⁻³ M.
Chemical reaction 1: PbCl₂(s) → Pb²⁺(aq) + 2Cl⁻(aq).
Chemical reaction 2: NaCl(aq) → Na⁺(aq) + Cl⁻(aq).
Ksp(PbCl₂) = 1.7·10⁻⁵.
c(NaCl) = c(Cl⁻) = 0.0500 M.
Ksp(PbCl₂) = c(Pb²⁺) · c(Cl⁻)².
c(Pb²⁺) = Ksp(PbCl₂) ÷ c(Cl⁻)².
c(Pb²⁺) = 1.7·10⁻⁵ M³ ÷ (0.0500 M)².
c(Pb²⁺) = 0.000017 M³ ÷ 0.0025 M².
c(Pb²⁺) = 0.0068 M = 6.8·10⁻³ M.
No Ag cannot react with NaOH because Ag is less reactive than Na in the reactivity series and can't displace it
<h3>
Answer:</h3>
H₂O
<h3>
Explanation:</h3>
The additional product that balances the reaction is water (H₂O).
- Therefore, the complete balanced equation for the reaction is;
H₂SO₄(aq) + 2NaOH(aq) → Na₂SO₄(aq) + H₂O(l)
- Balancing a chemical equation ensures that the law of conservation of mass is obeyed by the reaction.
- The reaction is an example of a neutralization reaction where an acid, H₂SO₄, reacts with a base, NaOH to form a salt and water.
- In this case the salt formed is sodium sulfate (Na₂SO₄)
