Question

Ph3+202=h3po4 овр . . . . .

Answer 1

Ответ:

ОВР является 1

p -3 - 8e = p +5 8 1

o2 + 4e = 2o -2. 4 2

ph3 - фосфин - восстановитель

о2 кислород - окислитель

Answer 2

It seems like you've provided a chemical equation, but it's not completely balanced. The equation you've given appears to represent the reaction between phosphine gas (PH3) and oxygen gas (O2) to form phosphoric acid (H3PO4). To balance this equation, you need to make sure that there are the same number of each type of atom on both sides of the equation. Here's the balanced equation:

4 PH3 + 5 O2 → 6 H3PO4

Now, there are 4 phosphine molecules reacting with 5 oxygen molecules to produce 6 molecules of phosphoric acid. This equation is balanced in terms of both mass and charge.
