Binding energy, amount of energy required to separate a particle from a system of particles or to disperse all the particles of the system.
Answer:
0.875 time.
Explanation:
The length of plastic water bottles are bought in the United States every day = (the no. of plastic water bottles are bought every day)(length of each bottle) = (140.0 million bottle)(0.25 m) = 35.0 million meter.
The length of the equator of the earth = 40.0 million meter.
∴ The times can the Earth's equator be circled by a line of plastic bottles used in the United States every day = (The length of plastic water bottles are bought in the United States every day)/(The length of the equator of the earth) = (35.0 million meter)/(40.0 million meter) = 0.875 times.
Answer:
14. (C) -3; 16. B. 0, 3
Explanation:
14. Ionic charge
X: ns²np³.
The element is three electrons short of having a complete octet.
It is likely to react chemically to add those three electrons and form an X³⁻ ion.
16. Orbitals in subshells
The n = 1 shell contains no p orbitals. All the other shells contain three p orbitals.
The n = 1 shell contains only one s orbital. Every higher shell contains a p subshell, and each p subshell contains three p orbitals.
