1. 9.36 moles S

2. 0.213 moles Al

<h3>Further explanation</h3>

Given

Reaction

2Al+3S⇒Al₂S₃

Required

moles of S

moles of Al

Solution

The reaction coefficient in a chemical equation shows the mole ratio of the compounds involved in the reaction (reactants or products)

  • 1. 3.12 moles Al₂S₃

From equation, mol ratio of Al₂S₃ : S = 1 : 3, so mol S :

= 3/1 x mol Al₂S₃

= 3/1 x 3.12

= 9.36 moles S

  • 2. 0.32 moles S

From equation, mol ratio of Al : S = 2 : 3, so mol Al :

= 2/3 x mol S

= 2/3 x 0.32

= 0.213 moles Al

When a piece of sodium metal is kept in water in chemical equation​
jekas [21]

Explanation:

Sodium metal reacts rapidly with water to form a colourless basic solution of sodium hydroxide (NaOH) and hydrogen gas (H2). The reaction continues even when the solution becomes basic. The resulting solution is basic because of the dissolved hydroxide.

10. Which of the following best describes the reaction 2VO3– (aq) + Zn (s) + 8H+ (aq) → 2VO2 (aq) + Zn2+ (aq) + 4H2O (l)? ______
Oduvanchick [21]
Correct answer is option E. <span>It is a redox reaction in which Zn is oxidized at the anode, and V is reduced at the cathode.

Reason:
In above reaction, the oxidation state of VO3- is +5, while that of VO2 is +4. Thus there is reduction of V from +5 to +4
In case of Zn, oxidation state of Zn is increased from 0 to +2, Thus process is referred as oxidation. </span>
