If I only have the name of this transitional coordination compound, bis(enthylenediamine)dinitroiron (III) sulphate how do you find the 2 outside the square bracket of this same thing but in formula form? [Fe (en)2 (NO2)2]2SO4 thanks.

Hi, I have few questions from a chemistry lab that i did, 1) I'm not sure whats the point of heating a nitrate (NaNO3) 2) I'm not sure why you add NaOH to NaNO3 after it has dissolved in water 3) I'm not sure why do we have to test what gas is produced fr...

Hi I was wondering if this equation is reversible and be written lime this: NaNO3 + H2O ⇋ NaOH + HNO3 Thanks!

If I heated NaNO3, would there be yellow gas inside the test tube?

Hi, I was wondering why is there white smoke when nh4cl and ca(oh)2 is being heated. Thanks!

Hi, what is the PH for NH3 in gas form? When I tested it with PH paper it showed a number around 8-9.5, but from searching online its a higher number. I'm not sure which one is correct. Thanks

Hello, Sorry to bother you all, but i have a quick question. If I needed to use heat in a reaction, for example, Ca(OH)2(s) + 2NH4Cl(s) = 2H2O(g) + 2NH3(g) + CaCl2(s) Do I need to put "+heat" on the reactant side when writing my equation? Thanks in advanc...

Hello, Which one is correct? 1) NaOH(aq) + HNO3(aq) ⇋ NaNO3(aq) + H2O(l) or 2) NaNO3(s) + H2O(l) ⇋ NaOH(aq) + HNO3(aq) Thanks!!

Hello, If I add water to a solid, how do i represent it in a equation with phases? for example the NaNO3 was the solid in this case and H2O was the liquid, does NaNO3 turns into an aqueous or stays as solid when I write the equation? Which one would be co...

Is this a valid equation? NaNO3 + H2O = NaOH + HNO3 Why or why not?

Hello, Is nano3 + h2o -> naoh + hno3 correct?

If I add water to NaNO3 does it make HNO3 and NaOH? For example NaNO3 + H2O -> HNO3 + NaOH is that equation correct? Please explain if it's not. Thanks!

Hello, Is there a reaction when NaNO3 is added to some H2O? Or does it just dissolves? Please explain why, thanks!

Hello, So I have recently done a lab with cobalt(II) nitrate and NaOCl (bleach) and our objective was to determine if colbalt or the bleach is part of the rate determining step. With the lab we have done trials by diluting the colbalt and leaving the conc...

Hi, for #3 i mean why do we have to heat calcium hydroxide with ammonium chloride?

Hi, I tested it with moist PH paper, i think its from the water vapour, what PH was i suppose to get?

Then what is the white smoke?

Do I have to put it, or can I just leave it out?

Is this correct though? NaNO3(s) + H2O(l) = NaOH(aq) + HNO3(aq)

I don't understand how it turns into aq when its a solid I add into the water, isn't only the products turn into aq?

So despite having to shake the test tube for it to dissolve into the water, NaNO3 in this case would be considered as Aqueous?

I meant NaNO3 + H2O -> NaOH + HNO3 is this valid?

Hi DrBob222, Can I express it in this form? NaNO3(s) + H2O(l) ==> NaNO3(aq)

Where did NaNO3 + HNO3 come from?

How about if I put the "H2O" above the arrow, and wrote NaNO3(aq) as my answer, would that be correct?
