Question

1) Na + HCI= 2) KOH + H2SO4=3) MgO + CaCO3=4) NaOH + HNO3=5) HNO3+Al(OH)3=6) Ca0+P205=7) Fe+C12=​

Answer 1

Ответ:

Na + HCl = NaCl + H2

KOH + H2SO4 = K2SO4 + H2O

MgO + CaCO3= CaO + MgCO3

NaOH + HNO3 = NaNO2 + OH

3 HNO3 + Al(OH)3 = Al(NO3)3 + 3 H2O

Ca0 + P2O5 = Ca3(PO4)2

Fe + C12 = FeC13

Answer 2

Chemical Reactions:

1) Na + HCI: When sodium (Na) reacts with hydrochloric acid (HCI), it forms sodium chloride (NaCl) and hydrogen gas (H2). The balanced chemical equation for this reaction is:

2Na + 2HCI -> 2NaCl + H2

2) KOH + H2SO4: When potassium hydroxide (KOH) reacts with sulfuric acid (H2SO4), it forms potassium sulfate (K2SO4) and water (H2O). The balanced chemical equation for this reaction is:

2KOH + H2SO4 -> K2SO4 + 2H2O

3) MgO + CaCO3: When magnesium oxide (MgO) reacts with calcium carbonate (CaCO3), it forms magnesium carbonate (MgCO3) and calcium oxide (CaO). The balanced chemical equation for this reaction is:

MgO + CaCO3 -> MgCO3 + CaO

4) NaOH + HNO3: When sodium hydroxide (NaOH) reacts with nitric acid (HNO3), it forms sodium nitrate (NaNO3) and water (H2O). The balanced chemical equation for this reaction is:

NaOH + HNO3 -> NaNO3 + H2O

5) HNO3 + Al(OH)3: When nitric acid (HNO3) reacts with aluminum hydroxide (Al(OH)3), it forms aluminum nitrate (Al(NO3)3) and water (H2O). The balanced chemical equation for this reaction is:

3HNO3 + Al(OH)3 -> Al(NO3)3 + 3H2O

6) CaO + P2O5: When calcium oxide (CaO) reacts with diphosphorus pentoxide (P2O5), it forms calcium phosphate (Ca3(PO4)2). The balanced chemical equation for this reaction is:

3CaO + P2O5 -> Ca3(PO4)2

7) Fe + Cl2: When iron (Fe) reacts with chlorine (Cl2), it forms iron(III) chloride (FeCl3). The balanced chemical equation for this reaction is:

2Fe + 3Cl2 -> 2FeCl3
