Vertical Column is a group
Horizontal is Period
Aliki earth metals is a group
Lithium- Neon is both
Based on electrons are both
Number of electron shells is both
The answer is: 1.5 moles of oxygen are present.
V(O₂) = 33.6 L; volume of oxygen.
p(O₂) = 1.0 atm; pressure of oxygen.
T = 0°C; temperature.
Vm = 22.4 L/mol; molar volume at STP (Standard Temperature and Pressure).
At STP one mole of gas occupies 22.4 liters of volume.
n(O₂) = V(O₂) ÷ Vm.
n(O₂) = 33.6 L ÷ 22.4 L/mol.
n(O₂) = 1.50 mol; amount of oxygen.
The answer would be 5. because the last zero is a holding place because the number is in front of the decimal. They other zero counts because they are being sandwiched.<span />
The binding energy in MeV per atom is - 63284.56 Mev.
The amount of energy needed to detach a particle from a system of particles or to disperse every particle in the system is known as the binding energy. Subatomic particles in atomic nuclei, electrons attached to atom's nuclei, and atoms and ions bonded together in crystals are three examples of where binding energy is very relevant.
If we have a nucleus with Z protons and N neutrons and mass MA, where A = Z + N then its binding energy in MeV is given by: Eb(MeV) = (Zmp + Nmn - MA) x 931.494 MeV/u
Mass of atom = 69.955264 amu
Mass of proton = 1.007825 amu
Mass of neutron = 1.008665 amu
Binding energy, Mev = (Zmp + Nmn - M) × 931.494MeV/u
= ( 1.007825 + 1.008665 - 69.955264) × 931.494
= - 67.938774 × 931.494
= - 63284.56 Mev
Therefore, the binding energy in MeV per atom is - 63284.56 Mev.
