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.

Two Half Cell reactions are as,
Reduction: PbO₂ + 2e⁻ → Pb²⁺
As it is acidic medium reaction, so add H⁺ on reactant side as it has more number of oxygen atoms and add H₂O on product side, and balance tehe elements, So,
4 H⁺ + PbO₂ + 2e⁻ → Pb²⁺ + 2 H₂O (1)
Oxidation: I⁻ → I₂ + 1e⁻
Balance Number of elements along with electrons,
2 I⁻ → I₂ + 2e⁻ (2)
Compare eq. 1 and 2,
4 H⁺ + PbO₂ + 2e⁻ → Pb²⁺ + 2 H₂O
2 I⁻ → I₂ + 2e⁻

Pioneer Species is a community that has reached a stable stage of ecological succession.
Answer:
The answer is
<h2>7.0 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of rock = 14 g
volume = 2 cm³
The density of the rock is
We have the final answer as
<h3>7.0 g/cm³</h3>
Hope this helps you
