(n^2 + 7)/(n + 3) = n – 3 + 16/(n + 3); For it to divide perfectly i.e. no remainder; (n^2 + 7)/(n + 3) must be an integer. but (n^2 + 7)/(n + 3) = n – 3 + 16/(n + 3); thus n – 3 + 16/(n + 3); must be an integer. thus 16/(n + 3); must be an integer Then you find n which will make...

1. - Provide example of additon polymer - Provide example of condensation polymer. - Outline how addition monomers have double bonds where as condensation does not. - Outline how a small molecule (such as water) is emitted from the condesation polymerisation process, where nothing is lost during...

A few people in my class got a motor to work brilliantly. They even attached a handcrafted fan out copper. Heres some things i noticed they did differently from the book. 1. Add extra magnets. 2. Alumnium foil = crapness. Used copper for brushes and commutator. 3. Turn up the power supply. GL

CSU online is alrite. Displays info in a table. The main features: 1. Pair of magnets/pair of Electromagnetic coils 2. Rotor Coil 3. Amature 4. Split-Ring Commutator 5. Brushes 6. External circuit/power supply 7. Axle

1. Find number of moles used up in titration. n = 0.15 x 11.4/1000 n = 1.71 x10-3 to neutralise 20mls of unknown 5n = 8.55 x10-3 to neutralise 100mls of unknown. NaOH- + HCl+ ----> H2 O + NaCl(aq) Thus 8.55 x10-3 moles in 100mls of unknown. 8.55 x10-3 x molar mass 8.55 x10-3 x (22.99 +16...

The time taken for the 500km journey is . 500/v (in hours) the cost is 150+v^2 for every hour. thus overall cost is 500/v x (150+v^2)

My teacher doesn't even both with the pump. Such a waste of time :P

Solvable only in terms of different pronumerals.

If u hate chem and its ur worst subject. Then drop it. Just make sure you use your frees productively

You can't get more then the maximum allocated marks. Remember that.

Re: IMPORTANT: The correct answers to commonly asked questions- read before you post. UAI caps on subjects do exist.

hydronium or hydrogen ions are effectively the same thing. To be specific, hydrogen ions don't ever exist on there own. They are always in the form of hydronium. A strong acid is one which readily forms hydronium ions. For example in HCl, 100% of the hydrogen will combine with water to...

State what the anode cathodes are made of. Write the equations State the electrolyte. Maybe add if ones rechargeable or not.

edit; nvmm too hardd

Don't generalise upon your personal experiences.

read the question properly nam :P AND OMG ITS JAAKKIE edit: You don't use the change in GPE formula for the first part basically.y.

who the fuck cares its year 11. Teacher forgot to mark a whole page of my test. I didnt tell him Who gives a fuck. edit: okay now thats out of the way: 1. Don't stress about bad marks in yr 11 2. Learn WHY you made the mistake. (Math and chem have the tendency to build on previous...

How many themes do we need to talk about in our essay. In particular for emma/clueless. Is two enough? Say i chose marriage & social class, do i still need to talk about transformations? Also is there a link to some past questions from emma/clueless. thx
