If the coefficient 2 is placed in front of the product tetraiodine nonaoxide (i4o9), then, how many atoms of each element must be accounted for on the otherwise of the equation

Number of iodine atoms = 2 × 4 = 8

Number of oxygen atoms = 2 × 9 = 18

Explanation:

Coefficient 2 is placed in front of the product tetraiodine nonaoxide:

=

Number of iodine atom in a single molecule tetraiodine nonaoxide = 4

Number of oxygen  atoms in a single molecule tetraiodine nonaoxide = 9

Coefficient 2 is placed in front of the product tetraiodine nonaoxide:

=

Number of iodine atoms = 2 × 4 = 8

Number of oxygen atoms = 2 × 9 = 18

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.

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
