Answer:

FIRST, if you are giving an exam, try to understand the long or short question first and then write the answer.

Second, Carefully look at the marks allotted to the long question. Suppose 3 marks are allotted to the question then you should thoroughly understand what the question is asking for and write a "to the point" answer. But if 5 or 10 marks are allotted to that question, then you should ADD all the DETAILS to your "to the point" answer.

Answer:

20g of AL = 20/26.98 MOL = 0.74 mol

30G of S = 30/32.07 mol = 0.94 mol

so, only min(.74/2,.94/3) = 0.31333 mol of Al2S3 can be formed:

.31333 mol Al2S3 = .61667*26.98g Al + .94*32.07 g S = 16.64g Al + 30g S

Abstract

CO2 is one of the major gases formed during coffee roasting, which has important implications on coffee’s quality and packaging requirements. In this STUDY, the residual CO2 content and CO2 degassing behavior of an Arabica coffee processed using a fluidized bed roaster, as affected by the roasting temperature-time conditions, were investigated. The results showed that positive correlations existed between the DEGREE of roast (expressed as lightness value) and residual CO2, IMPLYING that lightness could be used as an indicator of initial CO2 content in roasted coffee. At the same degree of roast, coffee roasted with high-temperature-short-time process had significantly higher CO2 degassing rate than those with low-temperature-long-time process. Moreover, the CO2 releasing rate increased with the degree of roast. The degassing rate of CO2 in ground coffee was highly dependent on the grind size and roasting temperature, but less dependent on the degree of roast. The different degassing behaviors observed between roasted coffee SAMPLES were explained on the basis of chemical composition and microstructural differences.

ANSWER:

EXOTHERMIC REACTION

Answer:

DALTON's law of partial pressure states that in a mixture of non-reacting gas, the TOTAL pressure exerted is equal to the sum of the partial pressure of the individual gases. Since NH3 and HCl are reacting gases, hence they don't obey Dalton's law of partial pressure.

Explanation:

Real gases do not obey Dalton's law of partial pressures. It is because these gases do not BEHAVE ideally and violate some of the rules of the KINETIC theory of gases. Real gases behave ideally only under CIRCUMSTANCES where the pressure is low and the temperature is high.

DALTON's Law, or the Law of Partial Pressures, states that the total PRESSURE EXERTED by a MIXTURE of GASES is equal to the sum of the partial pressures of the gases in the mixture.

The CONCENTRATION of P₄ will be more than the concentration of Cl₂

• From the reaction P₄ (S) + 6Cl₂ (g) ⇔ 4PCl₃ (g)  it is clear that 1 mole of P₄ reacts with 6 moles of Cl₂
• If both the REACTANTS were taken in equal AMOUNTS i.e, 1 mole in a vessel then for attaining EQUILIBRIUM 6 moles of  Cl₂ gets consumed
• Complete P₄ will not be consumed and some concentration of P₄ will remain at equilibrium

• So the concentration of P₄ is greater thn the concentration of Cl₂ at equillibrium i.e, [P₄] > [Cl₂]

To test whether the SEASHELL contains calcium CARBONATE, strong acids, such as Hydrochloric acid, can be added to it. If the sample does contain calcium carbonate, it will fizz and produce CARBON dioxide. Weak acids such as ACETIC acid will react, but less quickly.

Explanation:

Answer:

a) C3H6O   B) C4H6O3   c) VOCl3

Explanation:

a)   Carbon.                 Hydrogen               Oxygen

     0.180/12.0               0.030/1.0               0.080/16.0              

     = 0.015                    =0.030                   =0.005

     = 0.015/0.005          =0.030/0.005        =0.005/0.005

     = 3                            =6                           = 1

Therefore, the empirical formula is C3H6O

b) Hydrogen= 17.97g

   Oxygen= Carbon= (300-17.97)/2= 141.01g  

   Carbon.                 Hydrogen               Oxygen

     141.0/12.0               17.97/1.0               141.0/16.0              

     = 11.75                    =17.97                    =8.81

     =11.75/8.81              =17.97/8.81           =8.81/8.81

     = 1.33 X3                  =2.03  X 3           = 1

    = 4.                           =6.                        =3

Therefore, the empirical formula is C4H6O3

C) Hydrogen= 17.97g

   Oxygen= Carbon= (300-17.97)/2= 141.01g  

    VANADIUM                 Oxygen            Chlorine

     29.4/50.9               9.2/16.0               61.4/35.5              

     = 0.58                    =0.58                    =1.73

     =0.58/0.58            =0.58/0.58           =1.73/0.58

     = 1                           =1                          = 2.98 -> 3

    Therefore, the empirical formula is VOCl3
