This is an aplication of Le Chatelier Principle. So, if you need further details about the theory behind the answer, search for this subject.
Here is the answer and the explanation.
You can realize that 1 mol of reactant produce 2 moles of products, which means that the trend of the reaction is to increase the volume (at constant pressure) or to increase the pressure (at constant volume). If you realease the pressure by increasing the volume, Le Chaelier principle permit you to predict a displacement of the equilibrium to the right (to the products). This is, because the equilibrium will try to restore (increase) the pressure by producing more molecules.
So, the answer is the option B. There will be a shift toward the products.

Answer:
0.3 Coulomb charge flows through the toy car.
0.9 Joules of energy is lost by the battery
Explanation:
a)
Current drawn from the battery = 0.50 mA = (0.50 × 0.001 A)
milli Ampere = 0.001 Ampere
Duration of time current drawn = T = 10 min = 10 × 60 s = 600 s
1 min = 60 seconds
Charge flows through the toy car be Q
0.3 Coulomb charge flows through the toy car.
b)
Voltage of the battery = V = 3.0 V
Current drawn from the battery = 0.50 mA = (0.50 × 0.001 A)
Duration of time current drawn = T = 10 min = 10 × 60 s = 600 s
H = 0.9 Joules
0.9 Joules of energy is lost by the battery

3 moles of H2O *18g H2O/1 mol H2O
= 54 g H2O
