Where can you access the COLA test?

i liked it :)

How would you integrate |sinx|

1. montreal treaty: *replacing CFCs with HCFC or HFC *helping developing nations phase out the production of CFCs 2. HCFC: breakdown in the troposphere 3. HFCs: no clorine ^ steps taken need to assess how effective it is

Test for acidic/basic substances requires you to know what substances are acidic and basic.

accuracy - how close the result is from the accepted value. it can be improved by avoiding measuremental errors reliability - results are considered reliable if repeated measurements give the same value

PHB has similar properties to polypropylene. besides biocompatibility and biodegradability, its thermoplastic properties means it can be easily moulded for other purposes such as shampoo bottles [however, it's not economically viable yet]

my teacher said it's because adding base shifts equilibrium to the right. so even though acetic acid is weak, all of it eventually becomes ionised. and since both hcl and acetic acid are monoprotic, then the same amount is required. thank you for helping btw.

hmm, but i don't understand how this question is related to le chatelier's principle.

A sample of vinegar of concentration of 1M has a pH of 3. A 25mL sample of this 1M vinegar requires the same volume of 0.5M sodium hydroxide solution to reach the equivalence point of titration, as does a 25mL sample of 1M HCl. Explain why the same volume of NaOh is required for each titration...
