reaction with oxygen

• what are the two allotropes of phosphorus

  white phosphorus and red phosphorus
• how does white phosphorus react with oxygen

  burns instantaneously with a white flame producing a white powder with a white smoke
• how does red phosphorous react with oxygen?

  doesnt react at room temperature , heated in a jar with oxygen for a white flame producing a white powder with a white smoke
• what is the highest oxide of phosphorus?

  phosphorus 5 oxide - P4O10
• what is the oxide produced with phosphorus when there isnt enough oxygen?

  phosphorus 3 oxide - P4O6
• what is the balanced equation when phosphorus reacts with oxygen (highest oxide)

  4P + 5O2 = P4O10
• how does sulfur react with oxygen?

  sulfur is heated in a jar with oxygen producing a blue flame and an acidic choking gas
• what colour flame is produced when sulfur reacts with oxygen?

  blue
• what is the highest oxide of sulfur?

  sulfur trioxide - SO3
• what is the common oxide of sulfur?

  sulfur dioxide - SO2
• what is the balanced equation of the most common oxide of sulfur and the state symbols

  S(S)+ O2 (g) = SO2(g)
• what is the balanced equation of the highest oxide of sulfur with state symbols


  2S(s) + 3O2(g) = SO3(l)
• what is the balanced equation for sodium oxide and its state symbols?

  4Na(s) + O2(g) → 2Na2O(s)
• what is the balanced equation for magnesium oxide with state symbols?

  2Mg(s) + O2(g) → 2MgO(s)
• what is the balanced equation for aluminium oxide and its state symbols?

  4Al(s) + 3O2(g) → 2Al2O3(s)
• whats the balanced equation for siliciondioxide and its state symbols?

  Si(s) + O2(g) → SiO2(s)
• what is the balanced equation for posphorus oxide (highest oxidation state)

  4P(s) + 5O2(g) → P4O10(s)
• sulfurtrioxide is polar , sulfurdioxide is non-polar but sulfuretrioxide still had higher melting point because it has more van der waals forces
