We will begin by observing in a quantitative way decomposition of baking soda (NaHCO3). When NaHCO3 is heated, it decomposes to Na2CO3, CO2 and H2O. In this experiment, we will decompose a known amount of NaHCO3 and measure the mass of the Na2CO3 produced (actual yield). We will then compare this to the theoretical value using the percent yield calculation.

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
