5. How many moles of carbon dioxide (CO2) are produced from 15.6 grams of baking soda (NaHCO3)? (6 points)
3 NaHCO3 + H3C6H507 → 3 H2O + 3 CO2 + NazC6H507

The following reaction shows sodium carbonate reacting with calcium hydroxide. na2co3 + ca(oh)2 → naoh + caco3 how many grams of naoh are produced from 20.0 grams of na2co3? (molar mass of na = 22.989 g/mol, c = 12.01 g/mol, o = 15.999 g/mol, ca = 40.078 g/mol, h = 1.008 g/mol) 12.2 grams 15.1 grams 24.4 grams 30.2 grams

Asample of air with a volume of 2.20m3 at a pressure of 105 kpa and a temperature of 30c is cooled to 10c and the pressure is reduced to 75.0 kpa. what is the new volume? 6.9 1.34 2.56 43.0 2.88

In the space, show a correct numerical setup for calculating the number of moles of co2 present in 11 grams of co2
