3. When baking soda (sodium bicarbonate or sodium hydrogen carbonate, NaHCO3) is heated, it releases carbon dioxide gas, which is responsible for the rising of cookies, donuts, and bread.
a. Write a balanced equation for the decomposition of the compound (one of the products
is Na2CO3).
b. Calculate the mass of NaHCO3 required to produce 20.5 g of CO2

i dont know

explanation:

have a great day because if you dont you and i will be sad

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.
