Aqueous solution means the compound dissociate in water. But here it is not the case.
1. Not possible, because both are not solouble in water.
2. FeCl3 would be Fe 3+ + 3 Cl- and Sn(NO3)4 Sn 4+ + 4 NO3-
But also here no reaction, because everything is oxidised already.

A displacement is also a redox reaction. Check redox numbers of Cu and Zn

Re: Iron precipitation
Better use Ammonia in excess. Zinc get complex. Iron get hydroxide precipitation

Re: Seeking for program to spectrophotometer Halo Rb-10
Probably ask the manufacturer of the machine.

Re: Calculate the volume of gas under standard conditions
Molar mass propane C3H8 = 44 g/mol and butane C4H10 = 58 g/mol ratio 1:2 means 44 g : 116 g, in sum 160 g 12 kg is then 75 times more means 3300g propane and 8700 g butane. In mol its 75 : 150 mol Energy is 75 mol x 2220 kJ/ mol = 166500 kJ and 150 mol x 2850 kJ/mol = 427500 kJ in sum its 594000 kJ ...

What has stoichiometry to do with temperature.

Re: How is the volume of salt in the problem calculated?
Volume is not possible, only mass. Start with equation of saponification and also combustion. The moles CO2 refers of the amount of carbon and the water of the amount of hydrogen. The saponification gives also the moles of glycerol , where you can calculate the Fragment what is going away in mass. T...

Re: Complete these reactions
AgTiO2 and MnTiO2 cannot be. Silver is monovalent, manganese bivalent and titanium tetra valent. The 3 reactions I had given already. AgxTi(1-x)O2 and MnyTi(1-y)O2. Make also no sense . If you put 1 for x or y then it would give AgO2 and MnO2 Manganese would be possible, but then has to use Mn-IV co...

Re: Complete these reactions
That is only a hydrolysis.
Ti(OC3H7)4 + 2 H2O => TiO2 + 4 C3H7OH
The Hydroxide will give Manganese- or silver oxide, what will be built in the Titaniumdioxide particles
2 AgNO3 + 2 NaOH => Ag2O + 2 NaNO3 + H2O
MnSO4 + 2 NaOH => MnO + Na2SO4 + H2O
A reducer is able to reduce to silver.

Re: Temperature effect on the reaction
Figur out if the reaction is exothermic or endothermic.
If exothermic equilibrium shifts left, if endothermic it shifts right, if temperature is increase.
