mixture with baking soda is heated and has a mass loss of 0.325 g. Refer to Example Exercise 14.2 and calculate the percentage of NaHCO3 in the mixture. 1 mol H2 CO3 62.03 g H2 CO3 2 mol NaHCO3 1 mol H2 CO3 84.01 g NaHCO3 1 mol NaHCO3 [?B1] g H2CO3 x = [?B2] g NaHCO3 %D Percentage of NaHCO3 in the mixture = [?B3] %

chemical energy is stored in the chemical bonds of atoms and molecules. it can only be seen when it is released in a chemical reaction. when chemical energy is released, the substance from which the energy came is often changed into an entirely different substance.

this chemical reaction releases energy in the form of light and heat. chemical energy is the potential energy stored in the arrangement of atoms within molecules. breaking chemical bonds requires energy, while forming new chemical bonds releases energy.

the atp molecule can store energy in the form of a high energy phosphate bond joining the terminal phosphate group to the rest of the molecule. in this form,energy can be stored at one location, then moved from one part of the cell to another, where it can be released to drive other biochemical reactions.

i think its 100

i hope this !

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
