Question

So I’m in 6th grade and this is a chart. I need the # of molecules, # of atoms in each element and the total # of atoms 2H₂SO

Answer 1

1.) 2 molecules

2.) 4 H atoms, 2 S atoms, 2 O atoms

3.) 8 total atoms

Step-by-step explanation:

1.) 2 H₂SO

--------> The molecule is all of the elements bonded together (H₂SO). Because there is a coefficient of 2 in front of the molecule, this means that there are 2 molecules present.

2.) 2 H₂S₁O₁

---------> The number of atoms of each element is determined by the subscripts and the coefficients. In one molecule, there is one oxygen, one sulfur, and 2 hydrogen atoms (denoted by subscripts). Because there are two molecules, these values are doubled.

3.)

--------> The total number of atoms is calculated by adding the number of atoms of each element. If between 2 molecules there are 4 hydrogens, 2 sulfurs, and 2 oxygens, combined there would be a total of 8 atoms.
