When 16.35 moles of SI reacts with 11.26 moles of N2, how many moles of SI3N4 are formed
Allushta [10]

Answer:

5.450 mol Si₃N₄

Explanation:

Step 1: Write the balanced equation

3 Si + 2 N₂ ⇒ Si₃N₄

Step 2: Establish the theoretical molar ratio between the reactants

The theoretical molar ratio of Si to N₂ is 3:2 = 1.5:1.

Step 3: Establish the experimental molar ratio between the reactants

The experimental molar ratio of Si to N₂ is 16.35:11.26 = 1.45:1. Comparing both molar ratios, we can see that Si is the limiting reactant.

Step 4: Calculate the moles of Si₃N₄ produced from 16.35 moles of Si

The molar ratio of Si to Si₃N₄ is 3:1.

16.35 mol Si × 1 mol Si₃N₄/3 mol Si = 5.450 mol Si₃N₄

Answer:

D equal numbers of protons and electrons​

Explanation:

An atom of an element will always contain equal number of protons and electrons.

Atoms are electrically neutral because the number of positive charges and negative charges within them are always equal.

  • An atom is the smallest indivisible particles of an element that takes part in a chemical reaction.
  • The positively charged particles within an atom are the protons.
  • The negatively charged particles within an atom are the electrons.

For;

 So number of protons = number of electrons within an atom.
