Question

3Na+P=Na3Pрасставьте валентность​

Answer 1

Ответ:

Объяснение:

3Na +P = Na3P

Na(0) + P(0) = Na(+1)P(-3)

Answer 2

In the chemical formula 3Na + P = Na3P, we need to determine the valency of each element involved.

Valency is a measure of an element's combining capacity with other elements, and it is related to the number of electrons an atom gains or loses to form a chemical bond.

1. Na (Sodium) has a valency of +1. It tends to lose one electron to achieve a stable electron configuration in its outermost energy level.

2. P (Phosphorus) can have multiple valencies, but the most common valencies are -3, +3, and +5.

Now, let's balance the chemical equation:

3Na + P = Na3P

Since sodium (Na) has a valency of +1, and the subscript "3" in Na3P indicates three sodium atoms, the total valency of sodium in the compound is +1 x 3 = +3.

For phosphorus (P), we see that there is only one phosphorus atom in the compound, and its valency will be determined based on the overall valency of the compound.

The overall valency of the compound Na3P must be zero because in a balanced chemical equation, the total charge on the reactant side should be equal to the total charge on the product side.

So, let's find the valency of phosphorus (P) in this compound:

3 (valency of Na) + P (valency of P) = 0

3 + P = 0

P = -3

Therefore, the valency of phosphorus (P) in the compound Na3P is -3.
