2. Given the unbalanced equation: Na(s) +
H2O(1) -
NaOH(aq) +
Н.
When this equation is balanced, the reactant Na(s) and the product NaOH(aq) both have coefficients of
1) 1
2) 2
3) 3
4) 4

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
