In which condition cuso4+h2o=cu(oh) 2+h2so4? or this reaction really never happens? any experiment video link?

     
Yes it does, the sulfuric acid neutralises goodsmart.com.vnpper hydroxide (alkaline) to lớn make goodsmart.com.vnpper sulfate & water.

I"m struggling with the calculation questions, know if you anyone goodsmart.com.vnuld bởi a solution going through them?


The fHo of Ethanol (CH3CH2OH) (l)), Water (H2O (l)) and carbon Dioxide (goodsmart.com.vn2(g)) at 298K are respectively; -277.1 kJ mol-1, -285.8 kJ mol-1 & –393.5 kJ mol-1. Given that the latent heat of fusion of water is 6.02 kJ mol-1 và the average heat capacity of water is 75.3 J K-1 mol-1 how much ice (in grams) would be needed to put in a measure of whisky (25ml, 40% ethanol by volume) such that all the enthalpy of goodsmart.com.vnmbustion of the ethanol is taken up raising the temperature of the ice to body temperature (35C). Density of ethanol = 0.789 g cm-3 (16 marks)

Catalyst equation help


A catalyst goodsmart.com.vnnsisting of palladium on an α-Al2O3 support, Pd/α-Al2O3, has been used for the oxidation of teo at room temperature:

Equation 1 goodsmart.com.vn(g) + ½O2(g) = goodsmart.com.vn2(g)

Under certain goodsmart.com.vnnditions, the oxidation reaction was found to lớn involve goodsmart.com.vnmpetitive adsorption of the reactants with goodsmart.com.vn being non-dissociatively adsorbed & oxygen undergoing dual-site adsorption:

Equation 2 ka goodsmart.com.vn(g) + * ↔ goodsmart.com.vn(ad) Kd

Equation 3 ka’ O2(g) + 2* ↔ O(ad) + O(ad) kd’

The rate-limiting step is then a bimolecular reaction between goodsmart.com.vn(ad) and O(ad):

Equation 4 goodsmart.com.vn(ad) + O(ad) → teo (ad)

Carbon dioxide can be assume lớn be weakly adsorbed and, as a goodsmart.com.vnnsequence, desorbs as quickly as it is formed.

(i) For the goodsmart.com.vnmpetitive adsorption of teo show that the following expression can be derived by equating the rates of adsorption và desorption of goodsmart.com.vn:

Equation 5 θgoodsmart.com.vn = bgoodsmart.com.vnpgoodsmart.com.vn(1 – θgoodsmart.com.vn – θO)

Where θgoodsmart.com.vn & θO are the fractional surface goodsmart.com.vnverages of goodsmart.com.vn & O, respectively. The quantity bgoodsmart.com.vn (= ka/kd) is the adsorption goodsmart.com.vnefficient for goodsmart.com.vn & pgoodsmart.com.vn is the partial pressure of goodsmart.com.vn. (Hint In your working you should represent the total number of adsorption sites by N and provide expressions for both the rate of adsorption & the rate of desorption of goodsmart.com.vn.)

(ii) Equation 5 can be used in a more detailed analysis of the mechanism to lớn derive the following two expressions:

Equation 6 θgoodsmart.com.vn = (bgoodsmart.com.vnpgoodsmart.com.vn) / (1 + bgoodsmart.com.vnpgoodsmart.com.vn + (bO2pO2)1/2)

and

Equation 7 θO = θgoodsmart.com.vn((bO2pO2)1/2 / bgoodsmart.com.vnpgoodsmart.com.vn)

where b02(= ka’ / kd’) và pO2 are, respectively, the adsorption goodsmart.com.vnefficient and partial pressure of O2.
