Answer:
16. Option c.
Explanation:
The reaction is:
C₈H₁₈ + O₂ → CO₂ + H₂O
Let's count, we have 8 C, 18 H and 2 O in reactant side
We have 1 C, 2 H and 3 O in product side
In order to balance the C, we add 8 to CO₂ and to balance the H, we add a 9 to H₂O
Now we have 8 C on both sides and 18 H On both sides. Finally we have 25 O on product side.
C₈H₁₈ + O₂ → 8CO₂ + 9H₂O
To balance the O in product side we must add 25/2, but as it is a rational number, we must multiply x2 to get an integer number (x2 in all the stoichiometry). The balanced reaction is :
2C₈H₁₈ + 25O₂ → 16CO₂ + 18H₂O
with 16 C, 36 H and 50 O, on both sides

Answer:
The volume of basketball is 7216.5 cm³.
Explanation:
Given data:
Radius of ball = 12 cm
Volume of ball = ?
Solution:
We will apply the volume formula of sphere.
V = 4/3 ×π×r³
we know that,
π = 22/7
r = 12 cm
Now we will put the values in formula.
V = 4/3 × 3.14 × (12 cm)³
V = 4/3 × 3.14 ×1728 cm³
V = 7216.5 cm³
Thus, the volume of basketball is 7216.5 cm³.
Answer:
