Achemical engineer must calculate the maximum safe operating temperature of a high-pressure gas reaction vessel. the vessel is stainless-steel cylinder that measures 25.0 cm wide and 30.0 cm high. the maximum safe pressure inside the vessel has been measured to be 6.60 mpa. for a certain reaction the vessel may contain up to 0.800 kg of carbon dioxide gas.

calculate the maximum safe operating temperature the engineer should recommend for this reaction. write your answer in degrees celsius. round your answer to 3 significant digits.

Maximum safe operating temperature = 370°C

Explanation:

Radius of stainless steel vessel = 25.0/2 = 12.5 cm

height of vessel = 30.0 cm

Substitute the values in the above formula

Maximum safe temperature is calculated by using ideal gas equation

PV = nRT

pressure, P = 6.60 mPa =

R = 8.314 J/mol.K

molecular mass of CO2 = 44 g/mol

mass of CO2 = 0.800 kg = 800 g

T (K)=T (°C) + 273.15

643 K = T (°C) + 273.15

T = 643 - 273.15

   = 369.85 °C = 370°C

Maximum safe temperature = 370°C

1.consider the following balanced equation and answer parts a through. show calculations for each part.  

3 ag(s) + 4 hno3(aq) → 3 agno3(aq) + no(g) + 2 h2o(l)  

a. calculate the number of moles of agno3 produced by the reaction of 3 moles of ag with excess hno3. if the number to the left of the compound represents the number of moles of the compound which are present, then 3 moles of ag react with 4 moles hno3 to produce 3 moles agno3 (aq).

so the answer to a would be 3 moles.

b. calculate the number of moles of agno3 produced by the reaction of 108 grams of ag with excess hno3.  

i'm not sure how to plug in the grams of silver into an equation using moles to find how many moles are produced.

c. calculate the number of grams of agno3 produced by the reaction of 108 grams of ag with excess hno3  

d. calculate the number of moles of no produced as a byproduct of the reaction of 108 grams of ag with excess hno3.  

e. calculate the number of grams of no produced as a byproduct starting with 108 grams of ag and excess hno3.
