Question

I need to balance these...Please....
B. Lithium iodide and bromine react to produce lithium bromide and iodine.
LiI + Br2  LiBr + I2
C. Hexose (a type of sugar) burns in oxygen to produce water and carbon dioxide.
C6H12O6 + O2  H2O + CO2
D. Magnesium hydrogen carbonate produces magnesium carbonate and carbon dioxide and water.
Mg(HCO3)2  MgCO3 + CO2 + H2O
E. Calcium and hydrochloric acid produce calcium chloride and hydrogen gas.
Ca + HCl  CaCl2 + H2
F. Water and tellurium trioxide react to produce telluric acid.
H2O + TeO3  H2TeO4
G. Mercury (I) Oxide forms mercury and oxygen.
Hg2O  Hg + O2
H. Calcium chloride and sodium sulfate produce calcium sulfate and sodium chloride.
CaCl2 + Na2SO4  CaSO4 + NaCl
I. Aluminum and nickel(II) chloride produces aluminum chloride and nickel.
Al + NiCl2  AlCl3 + Ni
J. Butane burns in oxygen to form carbon dioxide and water.
C4H10 + O2  CO2 + H2O

Answer 1

(B) Lil + Br2 ⇒ LiBr + I2
(C) C6H12O6 + O2 ⇒ H2O + CO2
(D) Mg(HCO3)2 ⇒ MgCO3 + CO2 + H2O
(E) Ca + HCl ⇒ CaCl2 + H2
(F) H2O + TeO3 ⇒ H2TeO4
(G) Hg2O ⇒ Hg + O2
(H) CaCl2 + Na2SO4 ⇒ CaSO4 + NaCl
(I) Al + NiCL ⇒AlCl3 + Ni
(J) C4H10 + O2 ⇒CO2 + H2)

Answer 2

b)  2LiI+Br2------>2LiBr+I2
c]C6H12O6+6O2----------------->6H2O+6CO2
d] Mg(HCO3)2------------>MgCO3+CO2+H2O  already balanced
e]Ca+2HCl------------>CaCl2+H2
f)H2O+TeO3-------------->H2TeO4     already balanced
g]2Hg2O---------------->2Hg+O2
h]CaCl2+Na2SO4--------------->CaSO4+2NaCl
i]2Al+3NiCl2---------------->2AlCl3+3Ni
j]2C4H10+13O2--------------->8CO2+10H2O
