Question

Помогите выполнить задание Нужно вместо вопроса поставить формулу соответ. вещ-в H2O --> O2 + ? Я сделала так: 2H2O --> O2 + 2H2 Правильно ли?? А вот второе я не могу N2 + ? --> NO С объяснениями, пожалуйста

Answer 1

Первое вы сделали правильно.
вот второе N2 + O2 --> NO

Answer 2

Balancing Chemical Equations

To balance a chemical equation, you need to ensure that the number of atoms of each element is the same on both sides of the equation. Let's go through each equation and balance them step by step.

Equation 1: H2O -> O2

To balance this equation, you need to ensure that the number of hydrogen (H) and oxygen (O) atoms is the same on both sides.

On the left side, you have 2 hydrogen atoms (H2) and 1 oxygen atom (O). On the right side, you have 2 oxygen atoms (O2).

To balance the equation, you can multiply the water molecule (H2O) on the left side by 2:

2H2O -> O2

Now, the equation is balanced with 4 hydrogen atoms (2H2) and 2 oxygen atoms (O2) on both sides.

Equation 2: N2 -> NO

To balance this equation, you need to ensure that the number of nitrogen (N) and oxygen (O) atoms is the same on both sides.

On the left side, you have 2 nitrogen atoms (N2). On the right side, you have 1 nitrogen atom (N) and 1 oxygen atom (O).

To balance the equation, you can multiply the nitrogen monoxide molecule (NO) on the right side by 2:

N2 -> 2NO

Now, the equation is balanced with 2 nitrogen atoms (N2) and 2 nitrogen atoms (2NO) on both sides.

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