I am so stressed right now and am on the verge of a nervous breakdown. My chemistry homework is just really confusing and I need to pass this class, could someone please help me out? I need to hand this in tomorrow and I have already answered the questions myself but I feel like my answers are all wrong. I would appreciate it if someone could show me how to solve these so I know that when I hand this in tomorrow it won't bring my grade down even lower.

Complete and balance following equations: (find reactants and products)
1.Reactants: KOH+H2SO4
2.Reactants: FeS+HCl
3.Reactants: NaCl+H2SO4

If reaction occurs, list products. If no reaction occurs, state "no reaction":
1.Reaction: CaBr2+KOH
2.Reaction: Cu(OH)2+HC2H3O2
3.Reaction: FeS+2HCl
4.Reaction: Ca(NO3)2+2HClMy attemps: 1. H2SO4(aq) + 2KOH(aq) --> K2SO4(aq) + 2H2O(l)
2. FeS + 2HCl ------> FeCl2 + H2S
3. 2NaCl + H2SO4 = Na2SO4 + 2HCl(g)

1. CaBr2 + KOH = CaOH + KBr2
2. Cu(OH)2 + 2 HC2H3O2 = Cu(C2H3O2)2 + 2 H2O
3. ?
4. No reaction ?

Idk what it nmeans by listing products :/

Please post your answers - forum rules!
 
What part do you struggle with exactly? Part where you need to find the products? Or part where you need to balance the equation?

Both, but finding products in particular. I swear I'm not an airhead lol, I had a medical issues which caused me to miss school and now I'm so behind. :cry:

Sorry, I'm a new member so I wasn't aware of the rules. I just posted my attempts.

I'm not much of a chemist, but those look right to me.

I don't think so. See http://www.chemguide.co.uk/inorganic/group7/halideions.html.

A problem with the valencies?

The rest I leave to others.

Thread 'Humidity of a saturated NaCl solution with anticaking additive'

I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...

Thread 'Resists for etching Aluminium with NaOH'

I'm trying to find a cheap DIY method to etch holes of various shapes through 0.3mm Aluminium sheet using 5-10% Sodium Hydroxide. The idea is to apply a resist to the Aluminium then selectively ablate it off using a diode laser cutter and then dissolve away the Aluminium using Sodium Hydroxide. By cheap I mean resists costing say £20 in small quantities. The Internet has suggested various resists to try including... Enamel paint (only survived seconds in the NaOH!) Acrylic paint (only...
