There's no part f :/ Generally you want to know how many carbons, hydrogens, oxygens if any, are there. Then you want to know what kind of functional groups are present. Accordingly you'll have to arrange the functional groups and the length of the longest chain in order to get what you need. -

Primary alcohols, upon dehydration, will always give 1 product. Secondary or tertiary alcohols can give 1 or more products, as a result of this you can also have cis/trans products. Each counting as one product. Knowing this you can safely eliminate option A and C. Now you're left with B and... -

When the question states that Y gives a ppt "with" aqueous silver nitrate, you should immediately be able to remember that this is a test for halide ions. Which are the group 7 elements consisting of Cl, Br and I. The second part of the question is also important, since it can help us eliminate... -

Errr... This question is quite tricky to explain partially because of the fact that the question is based off of the syllabus back in 2009. Anyways, the process of forming the cyclic compound from J, is known as cyclic esterification. Cyclic esters are actually called lactones. The process is... -

Nope. It does react with alcohols, just not under warm conditions. They don't recommend using it because say for instance you want to prepare an aldehyde from a primary alcohol, KMNO4 will end up over oxidizing the alcohol all the way until it becomes a carboxylic acid. So yes it does react... -

Question 1: 2 C14H30 + 43 O2 ----------> 28 CO2 + 30 H2O 1 tonne = 1000 kg x tonnes = 10.8kg x = 0.0108 tonnes for 1 km For 8195 km = 8195 * 0.0108 = 88.506 tonnes Molar mass of C14H30 = 198g ---> 0.198 kg ------->1.98 x 10^-4 tonnes 88.506 / 1.98 x 10^-4 = 447,000 moles of C14H30 used for... -

Energy ( E ) = Power ( P ) * Time ( t ) Power = I^2 * R -----> ( 40 x 10^-3 )^2 * 60 = 24 J e.m.f = useful volts + lost volts Since 6.0 J is lost, we need to find how many volts are lost. Voltage ( V ) = Energy ( W ) / Charge ( Q ) Charge ---> Q = It = 40 x 10^-3 * 60 = 2.4 coulombs Voltage =... -

1 molecule of X produces 2 hydrogen atoms. The hydrogen atoms come off of the -OH group as H+, leaving behind -ONa. The reaction is, X + Na ---------> XNa + H2 The -OH group in X, has H replaced by Na. This gives 1 hydrogen atom. In the products we have two hydrogen atoms, so there has to be... -

N2 + 3H2 <---> 2NH3 Habers process involves an exothermic reaction. An exothermic reaction favours a lower temperature, and would produce yield at a faster rate and overall increase the total yield. Secondly you need to look at the x-axis, which is pressure. A higher pressure, would favour the...
