Answer:
Joule-Thomson coefficient for an ideal gas:
Explanation:
Joule-Thomson coefficient can be defined as change of temperature with respect to pressure at constant enthalpy.
Thus,
Also,
Also, is defined as:
Acoording to defination, the ethalpy is constant which means
For an ideal gas,
So,
Thus, ≠0. So,
Answer:
C) tellurium (Te) is the correct answer.
Answer:
In the middle of every atom is the nucleus. The nucleus contains two types of subatomic particles, protons and neutrons. The protons have a positive electrical charge and the neutrons have no electrical charge. A third type of subatomic particle, electrons, move around the nucleus
All of the elements in a period have the same number of atomic orbitals. For example, every element in the top row (the first period) has one orbital for its electrons.
Answer:
There are 26 valence electrons in SOF₂.
Explanation:
Valence electrons are calculated by adding the valence electrons present in valence shell of each element present in SOF₂. So,
# of Valence e⁻s in S = 6
# of Valence e⁻s in O = 6
# of Valence e⁻s in F = 7
# of Valence e⁻s in F = 7
Now, add all valence electrons,
= 6 + 6 + 7 + 7
= 26 Valence Electrons
