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.
Answer:
decane
Explanation:
due to more covalant bonds
The number of particles that are in 12.7 moles of compound that Jessica had is 7.65 x10^24 particles of compound ( answer E)
<u><em>Calculation</em></u>
<u><em> </em></u>The number of particles are calculated using the Avogadro's Principle constant.
- that is according to Avogadro's 1 moles = 6.02 x10^23 particles
what about 12.7 moles of compound= ? particles\
by use of cross multiplication
- number of particles of compound= [12.7 moles x (6.02 x 10^23)] / 1 mole = 7.65 x 10^24 particles of compound ( answer E)
N.b moles and moles cancels each other
An ionic compound consists of a metal AND a non-metal.
<em>Option A:</em>
Oxygen and fluorine are non-metals.
<em>Option B:</em>
Sodium and aluminium are non-metals.
<em>Option C:</em>
Calcium is a metal and chlorine is a non-metal.
<em>Option D:</em>
Nitrogen and sulfur are non-metals.
Thus, the answer is C.
