Make the equations of combustion reactions trace of substances in oxygen: 1) magnesium 2) calcium 3) silicon 4) hydrogen 5) silane (SiH4).

• 2Mg + O2 = 2MgO
Burning magnesium produces magnesium oxide
• 2Ca + O2 = 2CaO
When burning, calcium oxide is released
• Si + O2 = SiO2
When silicon burns, sand is released
• 2H2 + O2 = 2H2O
Burning produces water
• SiH4 + 2O2 = SiO2 + 2H2O
Burning produces sand and water



One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
