Question

Дописать уравнения:1)H2SO4+AL→ 2)HBr+Ba (OH)2→ 3)H2SO4+BaCl→ помогите срочно

Answer 1

3H2SO4+2AL→2AL(SO4)3 + 3H2
2HBr+Ba (OH)2→BaBr2 + 2H2O
H2SO4+BaCl2→2HCl + BaSO4

Answer 2

3Н2SО4+АL->АL(SО4)3->3Н2(стрелочка вверх) 
2НВr+Ва (ОН) 2->Н2Ва+2ВrОН 
Н2SО4+ВаСL2->ВаSО4+2НСL 

Answer 3

Уравнение 1: H2SO4 + Al → ?

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.

The balanced equation for the reaction between sulfuric acid (H2SO4) and aluminum (Al) is:

H2SO4 + 2Al → Al2(SO4)3 + 3H2

Уравнение 2: HBr + Ba(OH)2 → ?

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.

The balanced equation for the reaction between hydrobromic acid (HBr) and barium hydroxide (Ba(OH)2) is:

2HBr + Ba(OH)2 → BaBr2 + 2H2O

Уравнение 3: H2SO4 + BaCl → ?

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.

The balanced equation for the reaction between sulfuric acid (H2SO4) and barium chloride (BaCl) is:

H2SO4 + BaCl2 → BaSO4 + 2HCl I hope this helps! Let me know if you have any further questions.
