True. NH4CL is an ionic compound, and salts are strong electrolytes.
Answer:
5 moles of Fe₂(SO₄)₃ will be produced
Explanation:
Given data:
Number of moles of Fe₂(SO₄)₃ = ?
Number of moles of Fe react = 10 mol
Solution:
Chemical equation:
3H₂SO₄ + 2Fe → Fe₂(SO₄)₃ + 3H₂
Now we will compare the moles of iron and Fe₂(SO₄)₃ .
Fe : Fe₂(SO₄)₃
2 : 1
10 : 1/2×10 = 5 mol
5 moles of Fe₂(SO₄)₃ will be produced.
True because photon is a composite particle of a neutrino. It is solely based on the fact that emission and absorption of a photon corresponds to the creation of annihalation.
