Where’s the questions hun? I don’t even see the questions you need answered
atoms are made of 3 types of subatomic particles ; protons, neutrons and electrons.
Atomic number is the number of protons. Atomic number is characteristic for the element. So atoms of the same element will have the same number of protons.
mass number is the sum of protons and neutrons
Isotopes are atoms of the same element with different mass numbers. So since they are the same element the number of protons will be the same. But different mass numbers means number of neutrons will be different
therefore the three known forms of hydrogen are called A. isotopes
each of these forms will have the same number of A. protons
but different numbers of B. neutrons in their nuclei
I believe the strength comes from its ability to break the particle bond in the molecule. So the bond dissociation energy
Answer:
0.1529mol
Explanation:
Number of mole = x mol
Mass = 52.3g
Molar Mass of Sucrose
(C = 12, H = 1, O = 16)
C12H22O11
(12×12)+(1×22)+(16×11)
144 + 22 + 176
342g/mol
Number of Mole = Mass given/Molar mass
Number of mole = 52.3/342
Number of mole = 0.1529mol
