2NaHCO3 (s) —> Na2O (s) + 2 CO2 (g) + H2O (g)
Calculate the mass of sodium oxide, Na2O, produced if 0.5 g of sodium bicarbonate, NaHCO3 is decomposed

Molar mass NaHCO3= 84.006 g/mol
Molar mass Na20= 61.979 g/mol

away from the curb

explanation:

the wheels would then hit the curb if it started to rolling, decreasing the chance of an accident.

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
