Question

Дописать уравнения реакций, расставить коэффициенты а) реакция соединения:Ва+О2= оксид бария б) реакция разложения: АIN= нитрид алюминия в) реакция замещения: FeO+AI=железо+оксид алюминия г) реакция обмена:AI2 O3, + HCI = хлорид железа+вода Помогите пожалуйста✊❤❤

Answer 1

1. 2Ba + O2 = 2BaO
2. 2AlN = 2Al + N2
3. 3FeO + 2Al = Al2O3 + 3Fe
4. Al2O3 + 6HCl = 2AlCl3 + 3H2O

Answer 2

Equations and Balancing Coefficients

a) Reaction of compound: Ba + O2 = Barium oxide

To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Let's balance the equation step by step:

Step 1: Write the unbalanced equation: Ba + O2 = BaO

Step 2: Count the number of atoms on each side of the equation: On the left side: 1 Ba, 2 O On the right side: 1 Ba, 1 O

Step 3: Balance the atoms one by one: Since the number of Ba atoms is already balanced, let's balance the O atoms. To balance the O atoms, we need to add a coefficient of 2 in front of BaO: Ba + O2 = 2BaO

Now the equation is balanced with 2 Ba atoms and 2 O atoms on both sides.

b) Decomposition reaction: AlN = Aluminum nitride

Step 1: Write the unbalanced equation: AlN = Al + N2

Step 2: Count the number of atoms on each side of the equation: On the left side: 1 Al, 1 N On the right side: 1 Al, 2 N

Step 3: Balance the atoms one by one: Since the number of Al atoms is already balanced, let's balance the N atoms. To balance the N atoms, we need to add a coefficient of 2 in front of N2: AlN = Al + 2N2

Now the equation is balanced with 1 Al atom and 2 N atoms on both sides.

c) Replacement reaction: FeO + Al = Iron oxide + Aluminum

Step 1: Write the unbalanced equation: FeO + Al = Fe + Al2O3

Step 2: Count the number of atoms on each side of the equation: On the left side: 1 Fe, 1 Al, 1 O On the right side: 1 Fe, 2 Al, 3 O

Step 3: Balance the atoms one by one: Since the number of Fe atoms is already balanced, let's balance the Al atoms. To balance the Al atoms, we need to add a coefficient of 2 in front of Al: FeO + 2Al = Fe + Al2O3

Now the equation is balanced with 1 Fe atom, 2 Al atoms, and 3 O atoms on both sides.

d) Exchange reaction: Al2O3 + HCl = Iron chloride + Water

Step 1: Write the unbalanced equation: Al2O3 + HCl = FeCl3 + H2O

Step 2: Count the number of atoms on each side of the equation: On the left side: 2 Al, 3 O, 1 H, 1 Cl On the right side: 1 Fe, 3 Cl, 2 H, 1 O

Step 3: Balance the atoms one by one: Since the number of Cl atoms is already balanced, let's balance the Al atoms. To balance the Al atoms, we need to add a coefficient of 2 in front of Al2O3: 2Al2O3 + HCl = FeCl3 + H2O

Now the equation is balanced with 4 Al atoms, 3 Cl atoms, 2 H atoms, and 3 O atoms on both sides.
