Answer is 2.25 mol.
<em>Explanation;</em>
The balanced reaction equation is
2KMnO₄ + 5H₂O₂ + 3H₂SO₄ → K₂SO₄ + 2MnSO₄ + 8H₂O + 5O₂
The stoichiometric ratio between KMnO₄ and H₂O₂ is 2 : 5.
Hence,
moles of reacted H₂O₂ = moles of KMnO₄ reacted x (5/2)
= 0.90 mol x (5/2)
= 2.25 mol
Hence, your answer is correct.
<span>nitrate. you can tell because the anion is NO3, which cancels out C and D. it's not A either, because nitrite is NO2. :D </span>
Answer:
The limiting reactant is the 6.279 g of
Explanation:
We have to start with the <u>reaction</u> between sodium carbonate () and the Nickel (II) Chloride (), so:
We will have a <u>double replacement reaction</u>. Now we have to <u>balance</u> the reaction, so:
The next step is the <u>calculation of the moles for each reactive</u>. For we have use the <u>molarity equation</u>:
For the calculation of moles of we have to use the <u>molar mass</u> of the compound (129.59 g/mol):
The next step is the division of each mole value by the <u>coefficient of each reactive</u> of the balance reaction. In this case <u>we have "1" for each reactive</u>, so:
The final step is to <u>choose the smallest value</u>. In this case is the value that correspond to . Therefore is the limiting reactive.
