Answer:Therefore, there must be a direct relationship between these volumes of gases and the number of molecules they contain. Avogadro's law says that: Equal volumes of different gaseous substances, measured under the same pressure and temperature conditions, contain the same number of molecules.
Explanation:I hope it works for you.
Answer:
Hydrogen: -141 kJ/g
Methane: -55kJ/g
The energy released per gram of hydrogen in its combustion is higher than the energy released per gram of methane in its combustion.
Explanation:
According to the law of conservation of the energy, the sum of the heat released by the combustion and the heat absorbed by the bomb calorimeter is zero.
Qc + Qb = 0
Qc = -Qb [1]
We can calculate the heat absorbed by the bomb calorimeter using the following expression.
Q = C . ΔT
where,
C is the heat capacity
ΔT is the change in the temperature
<h3>Hydrogen</h3>
Qc = -Qb = -C . ΔT = -(11.3 kJ/°C) . (14.3°C) = -162 kJ
The heat released per gram of hydrogen is:
<h3>Methane</h3>
Qc = -Qb = -C . ΔT = -(11.3 kJ/°C) . (7.3°C) = -82 kJ
The heat released per gram of methane is:
According to molecular orbital theory, regions of wave function with highest probability of finding electrons are areas with constructive interference.
An electron is a negatively charged subatomic particle that can exist either free or bound to an atom (not bound). A bound electron is one of the three primary types of particles that make up an atom, along with protons and neutrons. Protons, neutrons, and electrons combined make up the atom's nucleus. A proton's positive charge balances an electron's negative charge. When an atom has an equal number of protons and electrons, it is said to be in a neutral state. Electrons are distinct from other particles in a number of ways. They have a much lower mass, are found outside the nucleus, and exhibit both wave- and particle-like characteristics. The electron is a basic particle.
