Question

А) Al + Ce2=AlCE3 , б) HgO=Hg + O2 , в)H2O2= H2O + O2, г)NH3= N2+ H2 , Д)Si + O2 = Si2O , е)KNO3+CaCE= KCE+Ca(NO3)2 ПОМОГИТЕ СРОЧНООО , нужно расставить коэффиценты и типы (замещение или соединение)

Answer 1

A)2Al + 3Cu2 = 2AlCu3 (соединение)
б)2HgO = 2Hg + O2 (разложение)
в)Там не нужны коэфиценты (разложение)
г)2NH3 = N2 + 3H2 (разложение)
4Si + O2 = 2Si2O (соединение)

Answer 2

Balancing Chemical Equations and Types of Reactions

a) Al + Ce2 = AlCe3 To balance the chemical equation for the reaction between aluminum and cerium, we need to consider the chemical properties of the elements involved. The balanced equation is: 2Al + 3Ce2 -> 2AlCe3 This is a combination reaction.

b) HgO = Hg + O2 The balanced chemical equation for the decomposition of mercury(II) oxide into mercury and oxygen is: 2HgO -> 2Hg + O2 This is a decomposition reaction.

c) H2O2 = H2O + O2 The balanced chemical equation for the decomposition of hydrogen peroxide into water and oxygen is: 2H2O2 -> 2H2O + O2 This is also a decomposition reaction.

d) NH3 = N2 + H2 The balanced chemical equation for the decomposition of ammonia into nitrogen and hydrogen is: 2NH3 -> N2 + 3H2 This is a decomposition reaction.

e) Si + O2 = SiO2 The balanced chemical equation for the reaction between silicon and oxygen to form silicon dioxide is: 2Si + O2 -> 2SiO2 This is a combination reaction.

f) KNO3 + CaCl2 = KCl + Ca(NO3)2 The balanced chemical equation for the reaction between potassium nitrate and calcium chloride is: 2KNO3 + CaCl2 -> 2KCl + Ca(NO3)2 This is a double displacement reaction.
