Methanol at 675°c and 1 bar is fed at a rate of 100 mol/s is fed to an adiabatic reactor where 25% of it is dehydrogenated to formaldehyde according to the reaction chaoh (g) hcho (g) +h2 (8). calculate the temperature of the gases leaving the reactor assuming that constant heat capacities of 17, 12, and 7 cal/mol°c for ch3oh, hcho, and h2, respectively are applicable. heat of formation for hcho (g) and ch3oh (g) are-27.7 and 48.08 kcal/mol

the answer is a and have a great day

they vary. it used to be meat, grain, bread, candy, beverages, donuts, and fruits/vegetables. now they added exercise in.

answer; the numbers of valence electrons in the acetic acid molecule (ch3co2h) is 24;

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
