    relative activity of metals question

    A student designed an experiment to investigate the relative activity of unknown metals, X, Y and Z. She placed each metal into a test tube containing the solution of metal ions indicated in the table and recorded her observations. Her results are shown below. <TABLE class=MsoNormalTable...

    galvanic cell anode cathode

    also because the metal is further up = more reactive = more readily oxidised, then it is a strong reductant, and will displace a metal thats further down the series. the rule for displacement thingy, if this is what youre asking about.. is that metals will react mre vigourously when they are...

    galvanic cell anode cathode

    say they give you two metals for the electrodes, to find out whether one is the anode or the cathode you can look at your data sheet for the standard potentials if a metal is higher i.e. towards the potassium reaction, then that means that it is more ready to lose it's electron, so its more...

    volumetric analysis question

    um, the problem i had initially was writing the chemical equation, so that the products were correct.. not the calculating part. so yeah when you say it didnt really help with anything.....hehe but its all cool now! i have my half yearlys for chem and music tomorrow!!...........:'( im...

    volumetric analysis question

    okay well i just used mum's equation to determine the mole ratio and molarity etc and so im guess that her logic was right my working out, just for the record was: 2KOH + (COOH)2.2H2O -> (COOK)2 + 4H2O data: KOH - 2moles , Vol.=47.8mL , M=? (COOH)2.2H2O - 1 mole, mass=0.26g, FW=126 amu...

    volumetric analysis question

    um so how exactly does it react? i asked my mum this and she said "according to the general word equation: Acid + Base -> salt + water the H+ from (COOH)2 [from (COOH)2.2H2O] reacts with the OH- from KOH to form water, the remainder is the salt, so the equation would have to be... 2KOH +...

    volumetric analysis question

    im havin trouble writing the equation for this problem find the molarity of potassium hydroxide if 47.8mL of it reacts completly with 0.26g of oxalic acid (COOH)2.2H2O i dont get the "(COOH)2.2H2O" part.. what exactly do you do with it

    answer to this ?

    excel says that 80% of SO2 generated is due to combustion of fossil fuels, and that motor vehicles contribute to only 1% emission so my best pick would either a or b, and since excel didnt mention any statistics on SO2's emmision due to smelting, then id pick b) combustion of fossil fuels...

    temp. affecting voltage

    can anyone explain to me how environmental temperature (or temperature of the external wire or anything else) affects the voltage of galvanic cells please? excel says that temperature affects the voltage without explaining it but im thinking that perhaps if the temperature of surroundings...

    strength vs proton donation

    mkay i can understand what Tennille is saying. but what about in conjuction with what i said earlier dispite the differig pH levels, are they still of the same acidic strength? or.. are they just both concidered strong because the pH is < 4

    strength vs proton donation

    actually, okay. i have another query conerning what insert-username said but lets say that we were just talking about strong acids. and their proton donation. if a strong acid was to have the ability to donate one proton, then would this mean that it was weaker, compared to another strong...

    strength vs proton donation

    hey cool :D that clarifies things thanks heaps!

    strength vs proton donation

    im abit confused about the relationship between the relative strength of an acid, and.. the number of protons that theyre able to donate..ie. whether the acid is monoprotic, diprotic or triprotic... im confused because i thought that when there are more H ions, (or something) present within...
