Calculate the grams of oxygen produced if 16.0 grams of lithium chlorate are completely decomposed by heating.
The equation of this reaction is 2LiClO3 --gt; 2LiCl + 3O2 if lithium chlorate is 16.0 grams; You can find the amount of substance: n(LiClO3) = m(LiCl)/M(LiCl); M(LiClO3) = 7+35.5...

What would it look like and does a reaction occur:
Fe and HCl
Zn and HCl
Cu and HCl
Fe and HNO3
Cu and HNO3
Zn and HNO3
Iron and zinc force out hydrogen from hydrochloric acid: Fe + 2HCl → FeCl2 + H2↑ Zn + 2HCl → ZnCl2 + H2↑ Copper is among tension after hydrogen therefore...

How many mL of concentrated HCL solution are needed to provide 90.0g of HCL? Concentrated HCL solution is 37.0% HCl by weight and has a density of 1.19 g/mL.
p =m/V 1,19 = 90/V V = 75,63 ml - it's volume of 37% HCL Need to solve a mass of full solution ( x = V(HCL)+(H2O) ), then 75,63...

What volume of 0.1248 M HCl should be added to a 5.0 g sample of CaCO3 for the CaCO3 to react completely.
CaCO3 (s) + 2 HCl ==>> CaCL2 + H2O + CO2 (g)
As one can see from the reaction equation, two moles of HCl reacts with one mole of calcium carbonate: n(CaCO_3 )=n(HCl)/2. The number of the moles of HCl equals: n(HCl)=c(HCl)·V(HCl)=0.1248...

What difference in conductivity would you expect to see, if any, in the following three solutions? 10M HCL, 1M HCL, and 0.1M HCL Explain why.
10M solution will be the most conductive, 1M will be 10 times worse to conduct electricity, 0.1M will be 100 times worse to conduct electric current. When dissolved in water,...

6.) A 11.5 ml solution of HCl has 0.531 g/L of HCl in solution. Calculate the concentration, amount of moles of HCl, and pH of the solution.
1)C(HCl)=0.531/36.5=0.0145 mol/L2)n(HCl)=0.531*0.0115/36.5=1.673 *10^-4 mol3)pH=-lg[H+]=-lg(1.673*10^-4)=3.78

Chlorine is used by manufacture to bleach cloth.
Na2S2O3 + 4Cl2 + 5H2O 2NaHSO4 + 8 HCl
How many kg of NaHSO4 (120) can be produced from 2.5kg of Na2S2O3(158) and how many kg
of HCl(36.5)?
2.5 kg = 2500 gMoles of Na2S2O3: 2500 g / 158 g/mol = 15.82 molAccording to the equation:Na2S2O3 + 4Cl2 + 5H2O = 2NaHSO4 + 8HClMoles NaHSO4 = 2 moles...
