When this reaction happens colour changes Yellow+Brown to Blood Red?? And What happens when adding Fe powder to the it?? Colour changes or Nothing happen????-When a source of iron(III) ions is combine

Notice I said reaction TIME and not reaction RATE. Im still confused on the difference could someone please just clarify the relationship between changing concentration (increase/decrease) and how it
the iupac name of ethylamine is ethanamine and not aminoethane.why so? i am getting so confused about when to use the suffix and when to use the prefix.some link on this topic would be very helpful.-A
Could someone help with these questions please? -The boiling points can be explained by the degree of molecular interactions.
(i) C has an -OH which allow for hydrogen bonding. D does not. So BP of
0.55g of hydrogen chloride (HCl) is dissolved in water to make 3.0Lof solution. What is the pH of the resulting hydrochloric acid solution?-First convert 0.55g of HCl into moles of HCl: 0.55/(1.01+35.
60/40 x 1000/250 mol/dm^3.-
Find the number of moles of NaOH you have
moles = mass / Molar mass
moles = 60 g / 40.00 g/mol = 1.50 moles
Now find the concentration in moles / L
C = moles / Vol (L)
What is the mass, in grams, of copper contained in 1kg of soil, if 2.5ppm is copper?
What I have done so far to attempt this problem:
* I have found the solute concentration by dividing the number o
The pH of an aqueous NaOH solution is 12.83. What is the hydrogen ion concentration of this solution?-Use either of these formula and plug it into the calculator.
[H+] = Inverse log - 12.83
or
pH = -

I missed a few days and so now Im trying to catch up. Am I doing this right?
If I have 21 liters of gas held at a pressure of 78atm and a temp. Of 900K, what will be the volume of the gas if I decreas
So water can dissociate according to the reaction:
H2O ⇌ H+ + OH-
The water is then heated so that is temperature rose by 5°C. How is it possible that the water remains neutral when its pH is decrea
