I feel silly asking for help on this question but I have spent 2 hours reading and trying to figure it out myself. Hope you guys can help.

I will type the question and hopefully you can guide me to the correct answer.

Potassium Peroxydisulfate K2S2O8, and important industrial bleaching agent is produced by the reaction (NH4)2S2O8 + 2KHSO4 = K2S2O8 + 2NH4HSO4

What Mass (in grams) of K2S2O8 would be produced when 50.0G OF (NH4)2S2O8 reacts with 50.0g of KHSO4?

I did attempt trying to do it but I could understand the equation or the way of getting it done. The question before it asked for the Limiting Reagent between (NH4)2S208 and KHS04 which I worked it out to be (NH4)2S2O8.

Hi Folks,
I am bringing this question to you, as no one else seems to answer my questions.
I hope you might be able to help with your vast chemistry knowledge.

I am a moderator for a group dedicated to African Dwarf Frogs, a fully aquatic frog
(www.flippersandfins.net)
We have seen a large increase in a certian fungus on amphibian skin (chytridiomycosis).

These frogs are very succeptible to this fungus, and it is deadly to them.
It kills by reproducing on their skin, messing it up, stopping o2 exchange, where they eventually suffocate and die.

The standard antifungal chemical we've used

I have here that the correct formula of mercury (I) arsenide is :
(Hg2)3 As2

Can someone help me understand how this was all put together?

Thanks

in grade 11 chem I learned and thought it was 2 electrons on the first orbit and 8 thereafter as the maximum until you reach the total number of electrons.

now if for example let's use silver the 47 element

has 47 electrons

how does my book come up with 1s₂ 2s₂ 2p₆ 3s₂ 3p₆ 4s₂ 3d₁₀ 4p₆ 5s₂ 4d₉?

I see on the priodic table the simplified is 5s1_4d10

why does an ideal gas change in temperature?? please be detailed
also what is the significance of 22.4? please be detailed

thank you very much
