Question

Как найти сумму коэффициентов в химическом уравнении? Al(OH)3+3HCl=AlCl3+3H2Oпожалуйста с объяснением) ​

Answer 1

Ответ:

Тут єсть гідроксил, який заберає всі не потрібні вуглеводи, лугів спиртів, не потрібні речовини.

Answer 2

Ответ:

Коэффициент - число, стоящее перед формулой молекулы. Оно показывает количество молекул (или моль) в реакции.

Коэффициент не равен 0, иначе бы в записи молекулы не было смысла. Запись Al(OH)3 означает 1 молекулу гидроксида алюминия. Просто коэффициент 1 не ставится (как и в любой науке).

Получается, что сумма равна:

1Al(OH)3+3HCl=1AlCl3+3H2O. 1 + 3 + 1 + 3 = 8

Finding the Sum of Coefficients in a Chemical Equation

To find the sum of coefficients in a chemical equation, you need to balance the equation first. Balancing a chemical equation involves adjusting the coefficients in front of each compound or element so that the number of atoms of each element is the same on both sides of the equation.

Let's take the chemical equation you provided as an example:

Al(OH)3 + 3HCl = AlCl3 + 3H2O

To balance this equation, you need to ensure that the number of atoms of each element is the same on both sides. Here's how you can do it step by step:

1. Start by counting the number of atoms of each element on both sides of the equation. In this case, we have:

Left side: Al: 1, O: 3, H: 3, Cl: 1 Right side: Al: 1, O: 3, H: 6, Cl: 3

2. Begin balancing the equation by adjusting the coefficients in front of the compounds or elements. In this case, we can start by balancing the hydrogen (H) atoms:

Al(OH)3 + 3HCl = AlCl3 + 3H2O

Now, the number of hydrogen atoms is the same on both sides.

3. Next, balance the chlorine (Cl) atoms:

Al(OH)3 + 3HCl = AlCl3 + 3H2O

Now, the number of chlorine atoms is also the same on both sides.

4. Finally, balance the aluminum (Al) and oxygen (O) atoms:

Al(OH)3 + 3HCl = AlCl3 + 3H2O

Now, the number of aluminum and oxygen atoms is the same on both sides.

After balancing the equation, we can see that the sum of the coefficients on both sides is equal:

1 + 3 = 1 + 3

Therefore, the sum of the coefficients in the balanced chemical equation is 4.

Please note that balancing chemical equations is a fundamental skill in chemistry and requires practice. There are various methods and techniques available to balance equations, such as the inspection method, algebraic method, and the ion-electron method. The method used may depend on the complexity of the equation.
