Answer:
The correct option is;
24 moles
Explanation:
Here, we have the reaction as follows;
Sn(s) + 2HF(g) → SnF₂ (s) + H₂ (g)
Therefore, one mole of Sn reacts with 2 moles HF to form one mole of SnF₂ and one mole of H₂
Molar mass of H₂ = 2.01588 g/mol
Therefore, the number of moles of H₂ in 48 grams of H₂ is given by the relation;

Since one mole each of SnF₂ and H₂ are produced, the number of moles of SnF₂ produced = 24 moles.
The number of moles of SnF₂ that will be produced is 24 moles.
Answer:
AL*3+ + 3e- =AL.
(10A×1930)÷96500=0.2mole e-
0.2÷3×27=1.8g(AL)
Answer:
Here is the meaning of covalent bond: covalent bond: a chemical bond in which two atoms share some of their valence electrons which creates a force that holds the atoms together
