Answer 1

Ответ:

Объяснение:

Fe203+2Al=Al2O3+2Fe

2Fe(OH)3=Fe2O3+3H2O

2KHCO3=K2CO3+H2O+CO2

2Al+3H2SO4=Al2(SO4)3+H2

3Mg+N2=Mg3N2

AlCl3+3NaOH=Al(OH)3+3NaCl

2Na3PO4+3MgCl2=6NaCl+Mg3(PO4)2

Answer 2

It seems like you've written a series of chemical reactions. Chemical equations describe the reactants and products in a chemical reaction. Here's a breakdown of the reactions you've written:

1. Fe2O3 + Al = Al2O3 + Fe: This appears to be a balanced chemical equation showing the reaction between iron (III) oxide and aluminum to form aluminum oxide and iron. The equation is not balanced.

2. Fe(OH)3 = Fe2O3 + H2O: This equation suggests the conversion of iron (III) hydroxide into iron (III) oxide and water. It's not balanced.

3. KHCO3 = K2CO3 + H2O + CO2: This equation represents the decomposition of potassium bicarbonate into potassium carbonate, water, and carbon dioxide. It is balanced.

4. Al + H2SO4 = Al2(SO4)3 + H2: This equation describes the reaction between aluminum and sulfuric acid to produce aluminum sulfate and hydrogen gas. It's balanced.

5. Mg + N2 = Mg3N2: This equation shows the formation of magnesium nitride from magnesium and nitrogen gas. It is balanced.

6. AlCl3 + NaOH = Al(OH)3 + NaCl: This equation represents the neutralization reaction between aluminum chloride and sodium hydroxide, resulting in the formation of aluminum hydroxide and sodium chloride. It's balanced.

7. Na3PO4 + MgCl2 = NaCl + Mg3(PO4)2: This equation appears to describe a double displacement reaction where sodium phosphate reacts with magnesium chloride to produce sodium chloride and magnesium phosphate. It is not balanced.

Balancing chemical equations is essential for ensuring that the number of atoms of each element is conserved on both sides of the equation. If you would like any of these equations to be balanced, please let me know, and I can help you balance them.
