Predicting 7 marker AAS - Assess impact to environment/society with its uses

damnit they are so hard to remember =S QUESTION: Discuss the need for alternative sources presently obtained from petrolchemical industry.

Biopolymers are polymers created naturally occuring biomass such as cellulose. They have superior properties than normal synthetic polymers are they are biodegradable, renewable and biocompatible. An example of a biopolymer is cellulose or starch. However, there have been developments to...

Cellulose is a natural condensation polymer composed of thousands of glucose monomers. During condensation polymerisation, the beta glucose monomers link together by 1-3 glycosidic bond to form cellulose. This glycosidic bond forms when two -OH react and condense out a water molecule. Celloluse...

Can someone post up the correct oxidation/reduction reactions for DRY CELL and SILVER BUTTON cell

Sulphur dioxide is used to produce sulphorous acid to preserve food such as pickles. It's low pH prevents the growth of microbes, allowing the food to stay fresher longer.

yay 2 hrs till exam

Qq

in this thread

what did u guys get for amplitude and period for 5b)?? amplitude = 2/3 ???

depends on your luck, one silly mistake and your out of the race

square of tangents = product of intercepts

For xy = 1/2 a^2 The focus is (a,a) ; (-a,-a) Directices: x + y = a and x + y = -a Eccentricity is always rt 2 so for xy=c^2 focus is ( rt 2 c ,rt c ) and ( -rt 2 c, - rt 2 c) ... just memorise it

plz make it as hard as 2000

*prays they make it very challenging*

Winkler Method (Titration) for testing the quantitative amount of DO in a sample. Note: the method involves fixing the amount of DO in a sample and determining the DO by titration later on. 1. Manganese (II) ions and hydroxide ions are added to the water sample. The amount of insoluble brown...

check out the school cert results for 2006, we have comparatively lower band 6s/5s for eng/maths than other years.

(ii) < ACB = < ADB = 90 degrees (tangents perpendicular to radius) <ACB + <ADB = 180 degrees BCAD is cyclic (opposite angles added up to 180 in a cyclic quadrilaterial) (iii) Since< ACB = 90 and < ADB = 90 Thus, AB must be diameter (< in semi circle = 90) But, AE = EB (=equal radius of equal...

From what I've heard, comparing last years results, you need around 70% for an E4 that is something like 8x/120. I reckon 80~86% i.e. 95~102/120 will get u mid 90s and 102+/120 will get you 95+. But since the marks distribution is a bell curve, you would need high 11x/120 to get the top marks.
