my answers are so far d, c, c, b ,b not sure for q6

These are the actual questions i have posted my solution on the above post, any suggestions chhers, Question 1 Which types of bonds can be identified in the IR spectrum of molecule B? Answer a. C=O and C=C b. C=O and O-H c. O-H only d. C=O only Question 2 By identifying the...

Homework Statement Spec diagrams are attached, could someone see if i am correct so far with these questions 1)Which types of bonds can be identified in the IR spectrum of molecule B? carbonyl group i believe 2) By identifying the molecular ion, determine which of the molecular formula...

Heyguys, could you have a look if i am on the right track Heres my working out to calculate the driving force in mass concentration units from the gas phase I converted 10 mol% to 0.17 mass%, (which is in mole fraction) then i calculated the partial pressures of inlet and outlet...

Any suggestions guys on calculating the mass transfer driving force?

Consider a chemical species A, which is soluble in water. The equilibrium of this system with A in air is described by the following question: C(air) = HC(water) where C(air) is mass concentration of the species in air C(water) is the mass concentration in water, and the Henrys Law constant...

Q.In which of the answers below are the substances listed in order of increasing melting point? a) Cl2 < CHF3 < H2O < CHCl3 < SiO2 b) Cl2 < CHCl3 < CHF3 < H2O < SiO2 c) Cl2 < CHF3 < CHCl3 < H2O < SiO2 d) Cl2 < H2O < CHF3 < CHCl3 < SiO2 e) SiO2 < H2O < CHCl3 < CHF3 < Cl2 How can we tell...

Homework Statement For the following situations of steady flow, determine whether the flow is laminar or turbulent based on Reynolds number: water at 10oC flowing at an average velocity of 2 m/s in a 100-mm pipe, (Viscosity of water at 10oC: 1.31 cP, density: 1000 kg/m3) Homework...

Any ideas guys?

wouldnt the overall pressure difference=850x1000x(12-0.6)=94962Pa so the reading could be 0.05+(pressure/94962)

Any thoughts guys?

The following are summary statistics for a data set. Would it be appropriate to use the Student's t- distribution to construct a confidence interval for these data? Explain clearly! Sample size = 10 Mean = 8.905 Median = 6.105 Standard deviation = 9.690 Minimum = 0.512 Maximum = 39.920...

that was for a different part of the question where "If water is used instead of cream, how high must the silo be in order for the display (calibrated for cream) to read 100% when the silo is full" but i can't seem to derive an equation to relate the display reading (in %) to the sensor...

so Stephen, your suggesting its not suitable to use tdistribution because its not normally disstributed but could there be any other reasons?

so would R=P/(pg0.6)*100
