Hey guys!
I need help with some problems from my chemistry homework
1.) When equation Fe2O3 +H2= Fe + H2O is balanced using whole-number coefficients, what is the coefficients of H2?
A.)6 B) 3 C)2 D) 1
2) Identify the spectator ion in this reaction
Ba(OH)2 + H2SO4= BaSO4 +H2O
3) Magnesium ribbon reacts with an aqueous solution of Cu(II) chloride in a single replacement reaction. What are the products of the balanced net ionic equation for the reaction?
4)expected products of decomposition reaction of potassium oxide, K2O?
A) K+ and O2- (charge is -2)
B) K+ and O2 (oxygen molecule)
C) K and O2(2-)
D) K and O2
thnx in advance!
