Answer:
The correct answer is <em>d. At equilibrium, the forward reaction and reverse reaction will have the same reaction rate.</em>
Explanation:
When a reaction begins, the reactants combine to form products. At the same time of product formation, the convertion of products into reactants also occur. The reaction reaches <em>chemical equilibrium </em>when the rate of forward reaction (the convertion of reactant into products) is equal to the rate of reverse reaction (the convertion of product into reactants). Upon this state, the concentration of reactants and products do not change in time (that does not mean that the concentration of reactants and products are equal, but that once the chemical equilibrium is reached, their concentrations at this point will not vary with the time because the forward and reverse reactions are occuring at the same velocity).
Answer:
10 kilowatts or 10,000 kw
Explanation:
Power = Force × Velocity
Given that:
Velocity of car is 50 m/s
The force is 200N
The power would be:
P = 200 × 50
P = 10,000 W
Notice that it only reaches watts because of the unit of the velocity is m/s. Standard unit to make Kw is km.
Since:
1 kw = 1000 w
10 kw = 10000 w

Answer:
See below, please
Explanation:
1 mol CH4 ——>2 mol H2O=2x18 g/mol= 36 g
The question is not clear. You should tell us the concentration of CH4, methane.
