Mass to Mass Stoichiometry Sodium peroxide reacts vigorously with water to produce sodium hydroxide
and oxygen. The balanced chemical equation is the following:
2Na2O2 (s) + 2H20(1)→ 4NaOH(aq) +O2 (g)
a) What mass in grams of H,0 is needed to react completely with 40.0 g of
Na,0,?
M(H2O) =18.02g/mol
M(Na, O2)=78 g/mol
Times
Molar

b..

is the correct one

explanation:

covalent bonds form as valence electrons are shared between two atoms. lewis structures and structural formulas are common ways of showing the covalent bonding in organic molecules. formal charge describes the changes in the number of valence electrons as an atom becomes bonded into a molecule.

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.
