Chemistry

Hey! I am doing a chem pre lab and i need to calculate the equilibrium concentrations. I know how to do this but i need help balancing the equation. The reactants are H2O2 and Na2S2O3 (both aqueous) and i believe they go to NaO and H2SO4 ???? Are those the right products. Could someone help me please!!!!

I read reading a book, and it said white gold is a mixture and not a compound. I don't understand how it's a mixture unless it's all melted. And when it's cooled down and formed into a ring, then isn't it a compound? I don't understand how it's a mixture instead of a compound. Is that because different amounts of gold and palladium are mixed, such as different percentages?

Is there a standard SI unit for volume? Would it be [math]m^3[/math]? I was reading a book, and it said people like to use [math]cm^3[/math], but that doesn't define what's considered standard.

What is Electron Affinity and what are the trends on the periodic table?

Anyone knows method of reducing carboxylic acid to alcohol that doesn't include LiAlH4?

I have wondered how this product works forever.it is this little packet that you can buy at REI. it is a clear liquid with a metle disk in it. when you slap the disk it heats up and turns into a solid. then you can boil it and it can be reused. it contanes sodium acetate (food grade [if that helps ]) and water. i asked all my science teachers and well nothing. any idias

I have a test tomorrow, and i have a question. Which intermolecualr forces are stronger liquids or gasses, and why. -thanks for any helps

im drawin a plan for somthing but i need to know how powerful the earths magnetic force is? what is it

Going through my textbook there isn't anything to explain this to me simply. Can anyone help? What is the [H3O+] of a 2.0M solution of the weak acid HA? Ka=1.8x10^-7

Why is water denser in the liquid state than in the solid state. I know it has something to do with hydrogen bonding and the particles sliding past each other. Can someone please explain.

Do neutrons attract each other?

if the chemcial reaction is CaCO3----> CaO + CO2, and if 40.0g of caco3 is decomposed, and 22.4 g of CaO is produced. if the question asks "where did the rest of the mass go", is it that it was burned off since its decomp in the form of CO2?

is [] = n / v or [] = v / n?

3 Questions: 1. Im confused on how the principle quantum numbers are related to the orientation of the sublevels, and energy levels. 2. I also dont understand why an s sublevel can only have 1 orbital, a p sublevel can only have 3 orbitals, a d sublevel can only have 5 orbitals, etc. 3. How can we tell wther or not an electron is in the ground or excited state based on electron configs.

I am a "virtual student'' in my school without a teacher and I need some urgent help with a question not covered in my textbook or other assignments. The question is: what is the solubility in g/L of AgI in a 0.040 M solution of MgI2 Ksp for AgI is 8.3 x 10 (to the power of -17) I have no idea where to start on this one and any help is greatly appreciated

Will someone please help me in determinig the polarity of a molecule

If the following could be show how to be balanced and answered with the shown dimensional analysis that would be great. Thanks! 1. In the decomposition of 242 L of carbon monoxide, at STP, what is the volume of oxygen gas produced? 2.If 27.36 g of silver metal were placed into a solutin containing 273.600 of magnesium nitrade, what would be the mass (if any) of magnesium metal formed? 3. A solution containing 666.0 g barium nitrate is added to a solution containing 666.0 g ammonium phosphate. What would be the mass of the precipitate formed (if any)? 4. If 4.04 g of hydrogen gas were to combine with an excess amount of oxygen gas, how many grams of wate…

We just startedt this topic in class and i dont understand it. I know this is a very basic problem but I need some help on where to start. If the partial pressures of oxygen and carbon dioxide are 565mm Hg and 225Hg respectivley, what would be the total pressure of the system?

Benzene (C6H6) reacts with nitric acid. Two products are produced, one of which is water. The other product is an oily liquid which has molar mass of 213 g/mol. It contains 33.8% Carbon, 1.42% Hydrogen, 19.7% Nitrogen, and 45.08% Oxygen. Write a balanced equation complete with descriptive symbols for this reaction. I converted each to moles so for carbon I got 2.816, Hydrogen 1.42, and Nitrogen, 1.407 and oxygen 2.8175. Then I divided by the smalles and expressed to a whole number ratio. So for each one respectively: Carbon 2, Hydrogen 1, Nitrogen 1 and Oxygen 2. So the supposed emperical forumula should be C2HNO2. The molar mass for the molecular formula is 21…

Other then batteries ! ! where can we get Carbon electrodes ?? And How to obtain it !?!?!

i need some help in that how can we explain the effect of temperature change on the rate of reaction in terms of boltzman distributions?

I know how a breathalyser works, but someone explain to me how it can give a relatively accurate reading of BAC? Is it the colour coding involved with the chemical reaction?

Hi everyone! Just wanted to start a new thread about everyone's current research interests...

what is the complete ionic equation of copper wire once put into a bunsen burner's flame. PLEASE HELP!!

i have been wondering why a solution does not have a constant freezing point. Anyone have any ideas? Not really sure ... my prof asked the class and asked us to find out... cant find any help so i wondered if anyone wants to give me some help. P.S. it is not homework for those who think i only am here for homework!
