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:
Equal
Explanation:
According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.
Answer:
The correct answer is option C.
Explanation:
Isoelectronic species are those atoms or ions which same number of electrons.But they differ in physical and chemical properties.
Atomic number of nitrogen atom is 7.
![[N]=1s^22s^22p^3](https://tex.z-dn.net/?f=%5BN%5D%3D1s%5E22s%5E22p%5E3)
![[N]^{3-}=1s^22s^22p^6](https://tex.z-dn.net/?f=%5BN%5D%5E%7B3-%7D%3D1s%5E22s%5E22p%5E6)
Number electron in nitride ions = 
Atomic number of oxygen atom is 8.
![[O]=1s^22s^22p^4](https://tex.z-dn.net/?f=%5BO%5D%3D1s%5E22s%5E22p%5E4)
![[O]^{2-}=1s^22s^22p^6](https://tex.z-dn.net/?f=%5BO%5D%5E%7B2-%7D%3D1s%5E22s%5E22p%5E6)
Number electron in oxide ions = 
![[Ne]=1s^22s^22p^6](https://tex.z-dn.net/?f=%5BNe%5D%3D1s%5E22s%5E22p%5E6)
Number of electrons neon = 
Hence, 
are isoelectronic.
