Ow many atoms of each element are in 4Na3PO4? 3 sodium, 1 phosphorus, 4 oxygen
4 sodium, 4 phosphorus, 4 oxygen
12 sodium, 1 phosphorus, 4 oxygen
12 sodium, 4 phosphorus, 16 oxygen

Explanation:

4Na₃PO₄

Each of the elements is multiplied by the number in front of the compound, and also by the subscript.

Therefore:

Number of Sodium (Na) = 4 × 3 = 12

Number of Phosphorous (P) = 4 × 1 = 4

Number of Oxygen (O) = 4 × 4 = 16

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

i'm pretty sure its b i might be wrong though!
