How many molecules of Sulphuric acid is needed to neutralise 5ml of Sodium Carbonate and 5 volumes of Tetraoxosulphate (VI) acid when Calcium is heated at a temperature of 200°C using Nickel as a catalyst?
This is a homework question. We have a policy which states that you should show your thoughts and/or efforts into solving the problem.

i have a question. i'm in physical science (9th grade) and the teacher's been talking about predicting products - the stuff we've done is stuff with two reactants and predict the products (think double displacement, single displacement, synthesis, decomposition, combustion, and a little bit of acid-base reactions). i'm a little ahead and the other day the teacher let me experiment with some of the lab materials out. I mixed sodium bicarbonate, calcium chloride, and water.
Beforehand, I wanted to predict the products. I know how to handle equations with two reactants, but this has three. How would I approach this?
that is, how do i predict the products of $\ce{NaHCO3 + H2O + CaCl2}$?
sorry: how do i predict the products of $\mathrm{NaHCO_3+H_2O+CaCl_2}$?
@heather as for the products I guess a hissing sound due to slaking of lime, heat evolution, but that bicarbonate ion is problematic; might release CO2 or might impart milkiness to Ca(OH)2. I am entirely not sure
There are 14 questions mentioning EAS, 82 questions mentioning "electrophilic substitution", and 48 questions mentioning "electrophilic aromatic substitution".
Currently, many of these are tagged "o-chem+reaction mech" or "o-chem+aromatic compounds". I think both of these are rather broad catego...

I'm in a site's main chatroom and I want to address a mod about something (not related to a specific post - so I won't flag a post), however, that particular mod hasn't been in the room in over 7 days (or is it 14?) so I can't tag them @[username]

@AvatarShiny killing buzzwords is fine, doesn't need to be super explicit, just when it shows up in the timeline, it should be easily recognisable ... not like in this example: chemistry.stackexchange.com/posts/89321/timeline
It amazes me that despite centuries of religion dominating almost every aspect of life in Britain or at the very least exerting a great deal of influence on the public and private sphere, the English language has managed to retain its non-Christian names of the week (with Tuesday through Friday d...
I have a couple of questions that I wanted to clarify:
1. Do radioisotopes appear in nature? Where do they come from?
2. I know that carbon dating lets us see the amount of Carbon 14 in it, but where did the Carbon 14 come from.
3. How do we predict what type of decay a random isotope will go thr...
First i balanced Fe by writing its half reaction , then i balanced Mn by writing its half reaction , now i multiplied the first reaction by 5 so as to neutralise the extra electrons
and that gave me the ratio asked as 5:1 . What am i doing wrong ?
@Tanuj is . . . What? Equations can solve every balancing, and they're good because you know solving the hardest one or two equations will get the result
Got this question i have no idea about . I mean it does involve dividing the total mass by the n factor or the valence factor , but i have no idea in this question how to do that
Iam unable to figure out what is the role of $\ce{CuCl}$ in Gatterman-Koch reaction. Does it provides $\ce{Cl-}$ by dissociating into $\ce{CuCl2}$ and $\ce{2Cl-}$, but that can also be achieved by using more $\ce{HCl}$? So why do we add $\ce{CuCl}$ in the reaction?

Or in one (C2O4)^2- unit, ON of C is +5, in CO2 it's +4, so çhange in ON for 1 C is 1, but we have 2 C's in it, so 2, like this we have 4 such (C2O4)2- units, so total change in ON is 4x2 = 8, the ON of everything else doesn't change
