Question

Составить эл.баланс, расставить коэффициенты!!! Помогите пожалуйста!!!! P4+AgNO3+H2O=H3PO4+Ag+HNO3

Answer 1

P4(0)-5e*4=4P(+5)|20 1
Ag(+1)+1=ag(0)|1 20
P4+20agno3+16h20=4h3po4+20ag+20hno3

Answer 2

P4 + 20AgNO3 + 16H2O = 4H3PO4 + 20Ag + 20HNO3, баланс:

P4 -20e- = 4P+5            | 20 | 20 |  1  |

Ag+ +e- = Ag                |  1  |      | 20 |;

возможно продолжение - р-ия Ag с HNO3.

Answer 3

Balancing the Chemical Equation

To balance the chemical equation P4 + AgNO3 + H2O = H3PO4 + Ag + HNO3, we need to ensure that the number of atoms of each element is the same on both sides of the equation.

Here is the balanced equation:

P4 + 10AgNO3 + 6H2O = 4H3PO4 + 10Ag + 10HNO3

Let's break down the balancing process step by step:

1. Start by counting the number of atoms for each element on both sides of the equation: - P: 4 on the left, 4 on the right - Ag: 1 on the left, 10 on the right - N: 1 on the left, 10 on the right - O: 3 on the left, 30 on the right - H: 2 on the left, 10 on the right

2. Balance the elements that appear in the fewest compounds first. In this case, we start with phosphorus (P): - Add a coefficient of 4 in front of H3PO4 on the right side to balance the number of phosphorus atoms.

P4 + 10AgNO3 + 6H2O = 4H3PO4 + 10Ag + 10HNO3

3. Next, balance the silver (Ag) atoms: - Add a coefficient of 10 in front of AgNO3 and Ag on the right side to balance the number of silver atoms.

P4 + 10AgNO3 + 6H2O = 4H3PO4 + 10Ag + 10HNO3

4. Now, balance the nitrogen (N) atoms: - Add a coefficient of 10 in front of HNO3 on the right side to balance the number of nitrogen atoms.

P4 + 10AgNO3 + 6H2O = 4H3PO4 + 10Ag + 10HNO3

5. Finally, balance the oxygen (O) and hydrogen (H) atoms: - Add a coefficient of 6 in front of H2O on the left side to balance the number of oxygen and hydrogen atoms.

P4 + 10AgNO3 + 6H2O = 4H3PO4 + 10Ag + 10HNO3

Now the equation is balanced, with an equal number of atoms on both sides.

Coefficients in the Balanced Equation

The coefficients in the balanced equation represent the number of molecules or moles of each substance involved in the reaction. In this case, the coefficients are as follows:

- P4: 1 molecule - AgNO3: 10 molecules - H2O: 6 molecules - H3PO4: 4 molecules - Ag: 10 atoms - HNO3: 10 molecules

Please note that the coefficients can also be interpreted as the ratio of the number of molecules or moles between the reactants and products.

I hope this helps! Let me know if you have any further questions.
