ive got a neap bio exam with solutions

i'm afraid you're incorrect. HCl is an acid that is more commonly found as a gas than an aqueous solution. HCl (g) + H20 (l) --> ......

You need to know: -energy graphs, ie: exothermic and endothermic ones. -metal reactions with acid, water, and oxygen -galvanic cells (electrochemistry) -pollution (crude oil etc) -distillation -all the common glassware (eg burette, volumetric flask etc) and HOW they're used -ionic and...

I understand. How many scenes should I focus on for each text? Am I allowed to "jump" from scene to scene when explaining HOW the power/powerplay is being represented? eg: if i talk about 6 types of powerplays am I allowed to use 6 short scenes from my prescribed text, and then 3 for each...

were you asking me a question? because maybe that's where the confusion lies, and i may have misinterpreted it lol could you sort of explain 5) a bit please? i dont know how it will let me find the "approx. conc. of the iron, before standard soln of iron maybe prepared."

this is how i am going to structure my essay, (if anyone can comment if it is a wise idea): 1. intro 2. Power and Control - context in both societies 3. Comparative study 4. Science and technology - context in both societies 5. Comparative study 6. Nature/environment - context in...

I've constructed an essay on this text and 2 others, but I don't know whether to focus more on "representation" or the actual "powerplay - who wins/loses power", or if I should balance the two out. My teacher told me to just focus on representation (language, techniques, etc) but that makes...

i have a few steps to analyse; i need to find out how these particular steps increases accuaracy. I've tried, but it's difficult. step 1) weight out 1.0g of fertiliser onto a piece of weighing paper and then transfer to a 250ml beaker. add 25ml of de-ionised water to dissolve. to this solution...

1) But the the question says "in 0.1M HCL" solution lol 2) the results for the water from the dam are quite low. water from a tank showing rusting would contain considerable levels of iron because the tank was constructed from iron material and if it undergoes rusting then iron ions...

Could you just explain your working out here? Can I use the C1V1=C2V2 formula in this situation?

Trial paper questions - AAS Hey just few questions I couldn't do, if you could lend a hand. It's to do with AAS. 1. The first question asks why standard solutions (iron ion standards in an AAS) were prepared in 0.1mol/L HCL solution. 2. Also, what would be a valid reason/hypothesis for...

Wouldn't you agree that the question is terribly worded? Or possibly that I have terribly misinterpreted it... shouldn't the equation be: HgO + O2 --> Hg + O2 It says "heating HgO" to obtain "Hg and O2"...but logically it makes no sense...

1. Identify the ions present in an aqueous LiOH solution. Li+, OH- 2. How many moles of oxygen are there in 10.46g SO2 ? MM (total)= 64 32:32 so, m(O2) = 5.23g n=m/MM so, n(O2) = 5.23g/16g/mol = .326875mol O2 3. What is the percent by mass of nitrogen N2O3 ? MM(total) = 76...

Mmmmm I suppose I shall agree with you there in some areas of sport, we do have flaws :) . Though you must remember we are more academically focused overall :P But still, everybody loses, and everybody wins.
