Question

решите химические реакции, заранее спасибо) Mg +O2= Ag+HCl= Na+H2O= Fe+CuCl2= Cu+H2SO4= Hg+H2O=

Answer 1

Mg+O2=Mg2O        Ag+HCl=AgCl+H          Na+H2O=Na2O+H             Fe+CuCl2=Fe(Cl)2+Cu

Cu+H2SO4= CuSO4+H2O         Hg+H2O=HgO+H2

 

 

Answer 2

Chemical Reactions:

1. Mg + O2 = ? The reaction between magnesium (Mg) and oxygen (O2) is a combustion reaction that forms magnesium oxide (MgO). The balanced chemical equation for this reaction is:

2Mg + O2 → 2MgO [[1]]

2. Ag + HCl = ? The reaction between silver (Ag) and hydrochloric acid (HCl) is a single displacement reaction. Silver displaces hydrogen from hydrochloric acid to form silver chloride (AgCl) and hydrogen gas (H2). The balanced chemical equation for this reaction is:

2Ag + 2HCl → 2AgCl + H2 [[2]]

3. Na + H2O = ? The reaction between sodium (Na) and water (H2O) is a highly exothermic reaction. Sodium reacts vigorously with water to form sodium hydroxide (NaOH) and hydrogen gas (H2). The balanced chemical equation for this reaction is:

2Na + 2H2O → 2NaOH + H2 [[3]]

4. Fe + CuCl2 = ? The reaction between iron (Fe) and copper(II) chloride (CuCl2) is a single displacement reaction. Iron displaces copper from copper(II) chloride to form iron(II) chloride (FeCl2) and copper (Cu). The balanced chemical equation for this reaction is:

Fe + CuCl2 → FeCl2 + Cu [[4]]

5. Cu + H2SO4 = ? The reaction between copper (Cu) and sulfuric acid (H2SO4) is a single displacement reaction. Copper displaces hydrogen from sulfuric acid to form copper(II) sulfate (CuSO4) and hydrogen gas (H2). The balanced chemical equation for this reaction is:

Cu + H2SO4 → CuSO4 + H2 [[5]]

6. Hg + H2O = ? The reaction between mercury (Hg) and water (H2O) does not occur under normal conditions. Mercury is not reactive with water.

Please note that these are simplified balanced chemical equations. The actual reactions may involve more complex species and conditions.
