Question

Поиогите решить H3PO4+KOH Fe+HCI Mg+CI2 CaO+H2O CH4+O2 AI+O2

Answer 1

Fe+2HCl=FeCl2+H2O-р.з
Н3PO4+KOH=K3PO4+H2O
Mg+CI2=MgCl2
CaO+H2O=CA(OH)2
4AI+3O2=2Al2O3

Answer 2

H3PO4 + KOH → K3PO4 + H2O This is a neutralization reaction between phosphoric acid (H3PO4) and potassium hydroxide (KOH). The products are potassium phosphate (K3PO4) and water (H2O).

Fe + HCl → FeCl2 + H2 This is a single replacement reaction between iron (Fe) and hydrochloric acid (HCl). The products are iron(II) chloride (FeCl2) and hydrogen gas (H2).

Mg + Cl2 → MgCl2 This is a synthesis reaction between magnesium (Mg) and chlorine gas (Cl2). The product is magnesium chloride (MgCl2).

CaO + H2O → Ca(OH)2 This is a combination reaction between calcium oxide (CaO) and water (H2O). The product is calcium hydroxide (Ca(OH)2).

CH4 + 2O2 → CO2 + 2H2O This is a combustion reaction between methane (CH4) and oxygen gas (O2). The products are carbon dioxide (CO2) and water (H2O).

2Al + 3O2 → 2Al2O3 This is a synthesis reaction between aluminum (Al) and oxygen gas (O2). The product is aluminum oxide (Al2O3).

I hope this helps! Let me know if you have any further questions.
