Answer: 2755.2 g of 
will be produced from 24.6 mol of haematite.
Explanation:
The balanced chemical equation is:
According to stoichiometry :
1 mole of 
produce = 2 moles of
Thus 24.6 moles of will produce=
of
Mass of 
Thus 2755.2 g of will be produced from 24.6 mol of haematite.
The additional information required to calculate the cost of the drive has been distance between the two cities. Thus, option B is correct.
The distance traveled by the object set the cost per unit has been given by the product of the distance and the cost.
<h3>Detail required for calculation cost</h3>
The given question has known cost of the fuel per gallon.
The mileage of the car has been known.
The distance traveled by the car has not been known. Thus, to calculate the cost of the drive, the distance between the two points has to be known. Thus, option B is correct.

Answer:
Equilibrium shifts to produce more reactant
Explanation:
- <em>Le Châtelier's principle</em> <em>states that when there is an dynamic equilibrium, and this equilibrium is disturbed by an external factor, the equilibrium will be shifted in the direction that can cancel the effect of the external factor to reattain the equilibrium.</em>
- When more product is added to the solution:
<em>This will increase the concentration of the products side, so the reaction will be shifted to the lift side (reactants side) to suppress the increase in the concentration of Products.</em>
<em />
<em>So, the right choice is: Equilibrium shifts to produce more reactant</em>
C. The answer is detroyed
Answer:
0.113 M
Explanation:
Since B and D are on opposite sides of the reaction, the concentration of D increases when the concentration of B decreases. The amount by which D increases is determined by the coefficients of B and D in the balanced chemical equation:
[D]=
(0.045 M)=0.113 M.
