Answer:
it has 79 protons
Explanation:
the atomic number is equal to the number of protons an element has.
Answer:
bonds within the nucleus of reactants atoms are broken and rearranged to form new product atoms
Since 1 mol --> 6.023x10^23 number of atoms/particles/molecules
Then do
1 : 6.023x10^23
6.72 : X
X= 6.72 x 6.023x10^23
X= 4.047x10^24 number of molecules
The molarity of the hydrogen peroxide solution from the information supplied in the question is 12.26 M.
Co = 10pd/M
Where;
Co = concentration = ?
p = percent of the hydrogen peroxide = 30%
d = Density of hydrogen peroxide = 1.39 g/ml
M = Molar mass = 34 g/mol
Substituting values;
Co = 10 × 30 × 1.39/34
Co = 12.26 M
The molarity of the hydrogen peroxide solution from the information supplied in the question is 12.26 M.
