3. Cl₂ + 2KI --> 2KCl + I₂

Cl = 2 Cl = 2

K = 2 K = 2

I = 2 I = 2

4. 2NaCl --> 2Na + Cl₂

Na = 2 Na = 2

Cl = 2 Cl = 2

5. 4Na + O₂ --> 2Na₂O

Na = 4 Na = 4

O = 2 O = 2

6. 2Na + 2HCl --> H₂ + 2NaCl

Na = 2 Na = 2

H = 2 H = 2

Cl = 2 Cl = 2

7. 2K + Cl₂ --> 2KCl

K = 2 K = 2

Cl = 2 Cl = 2

6. Consider the reaction: CzHo (g) + 02 (8) - 4 CO2(g) + 6H2O (1)

deff fn [24]

Answer:

1120 gm

Explanation:

6. Consider the reaction: CzHo (g) + 02 (8) - 4 CO2(g) + 6H2O (1)

(a) Balance the equation.

(b) How many grams of oxygen are required to react with 10 moles of ethane for a complete

combustion reaction?

FIRST, CORRECT THE EQUATION THEN BALANCE

2C2H6(G) + 7O2------------> 4CO2 + 6H2O

so for 10 moles of ethane, we need

7 X 5 = 35 MOLES O2

=35 MOLES O2

O2 HAS A MOLAR MASS OF 2X16 = 32 gm

35 MOLES OF O2 HAS A MASS OF 35 X 32 =1120 gm

PLEASE HELP!!

kondaur [170]

Number of moles of HCl = $\frac{mass (g)}{molar mass}$
= $\frac{27.8 g}{36.45}$ = 0.763 mole
From balanced equation:
4 moles of HCl give 2 moles Cl2
0.763 mole HCl give ?? mole Cl2
by cross multiplication :
= 0.38 mole Cl2
mass of Cl2 = moles x molar mass = 0.38 x 70.9 = 27 g
