Technoratibalanced equations
:cry:i need help to write out these equations and then to balance them i think i can do but i cant find out all of the equations. please help to write them out
1. solid iron (II) reacts with a solution of carbonic acid (dihydrogen carbonate) in water to form iron (II) bicarbonate that remains in dissolved water
2. molybdenum (IV) sulfide, a solid, reacts with oxygen to form molybdenum (VI) oxide, a solid, and sulfur dioxide, a gas
3. ammonia gas reacts with fluoride to produce ammonium fluoride , a solid, and nitrogen trifluoride, a gas
4. aluminum metal, reacts with aqueous sulfuric acis to form aluminum sulfate, that remains dissolved in water, and hydrogen
5. heptane,c7h16 a liquid reacts with oxygen to produce carbon dioxide , a gas, and water, a vapor
please help me to write these out so i can balance them
thanks
1. Fe(s) + H2CO3(aq) -> FeCO3(aq) + H2(g)
2. 2(MoS2)(s) + 5(O2)(g) -> 2(MoO3)(s) + 2(SO2)(g)
3. Not sure, as I don't know the exact formula for 'ammonium fluoride' and what fluoride you're using (ammonium fluoride can be NH4F or NH5F2)
4. 2Al(s) + 3(H2SO4)(aq) -> Al2(SO4)3(aq) + 3(H2)(g)
5. C7H16(l) + 11(O2)(g) -> 7(CO2)(g) + 8(H2O)(g)
I think the third would be:
4 NH3(g) + 3 F2(g) ---> 3 NH4F(s) + NF3(g)
Maybe also like this:
20(NH3)(g) + 29(F2)(g) ---> 6(NH5F2)(s) + 14(NF3)(g)
Pretty big! I see...
you should at least let the kid try to balance them.
