Mechanical waves are classified according to transverse waves.
Answer:
Balanced net ionic equation;
2MnO₄⁻ + 16H⁺ + 5C₂O₄²⁻ → 2Mn²⁺ + 8H₂O + 10 CO₂
Explanation:
- This is an example of a redox titration where acidified potassium permanganate (KMnO₄) is titrated against oxalic acid (H₂C₂O₄).
- A redox reaction is a type of reaction that involves both reduction and oxidation.
- One reactant of the reaction gains electrons(reduction) while another loses electrons(oxidation).
- During the redox reaction, H⁺/KMnO₄ undergoes reduction while the oxalic acid undergoes oxidation.
- Therefore, KMnO₄ is the oxidizing agent while H₂C₂O₄ is the reducing agent.
- The net ionic reaction will be;
2MnO₄⁻ + 16H⁺ + 5C₂O₄²⁻ → 2Mn²⁺ + 8H₂O + 10 CO₂
- From the reaction, MnO₄⁻ is reduced to 2Mn²⁺ while C₂O₄²⁻ is oxidized to CO₂.
- Therefore, two moles of KMnO₄ will react with 5 moles of oxalic acid.
Answer:
Explanation:
If this is a double replacement reaction or salt metathesis, then I have taken the liberty of including the symbol representing an aqueous solution, (aq), to the formulas in the equation written as CuCl2(aq)+2NaNO3(aq)→Cu(NO3)2(aq)+2NaCl(aq).
In order for a double replacement reaction to occur, one of the products must be a solid precipitate (a salt), an insoluble gas, or water. Since all species are in aqueous solution, none of these products occur, which means there is no reaction. The result is an aqueous solution containing Cu2+, Cl−, Na+, and NO3− ions.
The equation should be written as CuCl2(aq)+2NaNO3(aq)→No Reaction
Answer:
C
Explanation:
It is most likely non metal with a high electronegativity.
You just switch them around
