Question

Треба записати повне,розгорнуте та йонне рiвняння:2H+ + 2OH- = 2H2O.Будь ласка,допоможiть,термiново потрiбно....Я все знайшла,але коефiцiетнiв немае,що робити?

Answer 1

2H(+) + 2OH(-) = 2H2O
2H(+) + SO4(2-) + 2Na(+) + 2OH(-) =
2Na(+) + SO4(2-) + 2H2O
H2SO4+2NaOH=Na2SO4+2H2O

Answer 2

Writing the Balanced Chemical Equation: 2H + 2OH- = 2H2O

To write the balanced chemical equation for the reaction 2H + 2OH- = 2H2O, we need to ensure that the number of atoms on both sides of the equation is equal. This is achieved by adjusting the coefficients in front of the reactants and products.

In this case, we have two hydrogen atoms (H) on the left side and four hydrogen atoms (2H2O) on the right side. To balance the hydrogen atoms, we can place a coefficient of 2 in front of the hydrogen gas (H2) on the left side:

2H + 2OH- = 2H2O

Next, let's balance the oxygen atoms. On the left side, we have two hydroxide ions (OH-) which contain two oxygen atoms. On the right side, we have four oxygen atoms (2H2O). To balance the oxygen atoms, we can place a coefficient of 2 in front of the hydroxide ions (OH-) on the left side:

2H + 2OH- = 2H2O

Now, let's verify that the equation is balanced by counting the number of atoms on both sides:

On the left side: - Hydrogen (H): 2 atoms - Oxygen (O): 2 atoms

On the right side: - Hydrogen (H): 4 atoms - Oxygen (O): 4 atoms

As we can see, the number of atoms is now equal on both sides of the equation, and the equation is balanced.

Therefore, the balanced chemical equation for the reaction 2H + 2OH- = 2H2O is:

2H + 2OH- = 2H2O
