The equation below shows lithium reacting with nitrogen to produce lithium nitride. 6Li + N2 2Li3N If 12 mol of lithium were rea
Andreyy89

Answer:

4 mol  of lithium nitride would be produced

Explanation:

6Li + N2  → 2Li3N

This equation means that 6 mol of lithium are reacted with 1 mol of nitrogen to make, 2 mol of lithium nitride.

So this is the rule of three to find out, how many moles of lithium nitride are been made, from 12 mol of Li.

6 Li _____ 2 Li3N

12 Li ________ (12. 2) / 6 = 4 moles

Write a balanced equation using the correct formulas and include conditions (s, l, g or aq) for each of the following reactions.
Aloiza [94]

Answer:

2Fe(s) + 3Cl2(g) → 2FeCl3(s)

Explanation:

Step 1: Data given

iron = Fe = solid = Fe(s)

chlorine = Cl2 = gas = Cl2(g)

iron(III) chloride = FeCl3 = solid = FeCl3(s)

Step 2: The unbalanced equation

Fe(s) + Cl2(g) → FeCl3(s)

Step 3: Balancing the equation

Fe(s) + Cl2(g) → FeCl3(s)

On the left we have 2x Cl (in Cl2) and on the right side we have 3x Cl (in FeCl3). To balance the amount of Cl we have to multiply Cl2 (on the left) by 3 and FeCl3 by 2.

Fe(s) + 3Cl2(g) → 2FeCl3(s)

On the left side we have 1x Fe and on the right side we have 2x Fe (in 2FeCl3). To balance the amount of Fe, we have to multiply Fe on the left side by 2. Now the equation is balanced.

2Fe(s) + 3Cl2(g) → 2FeCl3(s)
