Answer:
1.17 mol
Explanation:
Step 1: Write the balanced equation
2 Al + 6 HCl → 2 AlCl₃ + 3 H₂
Step 2: Calculate the moles corresponding to 85.0 g of HCl
The molar mass of HCl is 36.46 g/mol.
85.0 g × 1 mol/36.46 g = 2.33 mol
Step 3: Calculate the number of moles of H₂ produced from 2.33 moles of HCl
The molar ratio of HCl to H₂ is 6:3.
2.33 mol HCl × 3 mol H₂/6 mol H₂ = 1.17 mol H₂

Answer: Option (a) is the correct answer.
Explanation:
When two or more atoms are chemically combined together then the product formed is known as a molecule.
These atoms can be bonded through either covalent or ionic bonds.
For example, a water molecule consists of two hydrogen atoms combined with an oxygen atom. Chemical formula of water is
.
Thus, we can conclude that an element can be made of many elements.
