Explanation:
Balanced Equation is 2ALCL₃₍ₐq₎ + 6NaOH₍ₐq₎ = 2Al(OH)₃₍s₎ + 6NaCl₍ₐq₎
Total Iconic Equation is AL²⁺+2CL₃⁻ + 6Na⁺+ 6(OH)⁻= Al²⁺(OH)₃⁻ + 6Na⁺+6Cl⁻
2CL₃⁻ cancels 6Cl⁻ from both sides
6Na⁺ cancels 6Na⁺ from both sides
the Net Ionic Equation is AL²⁺ ₍ₐq₎+ 6(OH)⁻₍ₐq₎= Al²⁺(OH)₃⁻₍s₎
Ответ:
a) Balanced equation
AlCl₃ (aq) + 3NaOH (aq) → 3NaCl (aq) + Al(OH)₃ (s)
b) Total Ionic Equation
Al³⁺(aq) + 3Cl⁻(aq) + 3Na⁺(aq) + 3OH⁻(aq) → 3Na⁺(aq) + 3Cl⁻(aq) + Al(OH)₃(s)
c) Net Ionic Equation
Al³⁺(aq) + 3OH⁻(aq) → Al(OH)₃(s)
Ответ:
4H2 + CO2 = 2H2O + CH4
so 4 moles H2 : 2 moles H2O = x : 19.1
you ll need x = 2x19.1 / 4
and that is 9.55 moles of hydrogen gas
