Title: Identify a balanced equation for the calcination of Al(OH)3.
Post by: Mollykgkg on Nov 18, 2019

Question 1

Identify a balanced reaction for the smelting of SnO2 with carbon.
◦ 2SnO2(s) + 2CaC2(s) 2SnC2(s) + 2CaO(s) + O2(g)
◦ SnO2(s) + CaCO3(s) SnC(s) + CaO(s) + O2(g)
◦ SnO2(s) + 2C(s) Sn(l) + 2CO(g)
◦ SnO2(s) + CO2(g) SnCO3(s)
◦ SnO2(s) + 2CO(g) Sn(l) + 2CO2(g)

Question 2

Identify a balanced equation for the calcination of Al(OH)3.
◦ Al(OH)3(s) + SiO2(s) AlSiO3(s) + 3H2O(g)
◦ Al(OH)3(s) + C(s) Al2O3(s) + CO2(g) + H2O(g)
◦ 2Al(OH)3(s) + 3CO(g) Al2O3(s) + 3CO2(g) + 3H2O(g)
◦ 2Al(OH)3(s) + O2(g) Al2O3(s) + 3H2O(g)
◦ 2Al(OH)3(s) Al2O3(s) + 3H2O(g)
