Hbr + khco3 --> h2o + kbr + co2 if i do this reaction with 30 grams of hbr, how many grams of carbon dioxide will be formed? make sure u use factor label method and show work!

Mass of carbon dioxide = 17.6 g

Explanation:

Given data:

Mass of HBr = 30 g

Grams of carbon dioxide produced = ?

Solution:

Chemical equation:

HBr + KHCO₃   → H₂O + KBr + CO₂

Number of moles of HBr:

Number of moles = mass/ molar mass

Number of moles = 30 g/ 80.91 g/mol

Number of moles = 0.4 mol

Now we will compare the moles of HBr and CO₂.

                             HBr                    :               CO₂

                               1                       ;                 1

                              0.4                    :              0.4

Mass of carbon dioxide:

Mass = number of moles × molar mass

Mass = 0.4 mol × 44 g/mol

Mass = 17.6 g

po-215 i got it right on the quiz

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
