Answer:
Final volume = V₂ = 8.2L
Explanation:
Given data:
Initial volume = 12.3 L
Initial pressure = 40.0 mmHg
Final volume = ?
Final pressure = 60.0 mmHg
Solution:
The given problem will be solved through the Boyle's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
40.0 mmHg × 12.3 L = 60.0 mmHg × V₂
V₂ = 40.0 mmHg × 12.3 L / 60.0 mmHg
V₂ = 492 mmHg. L / 60.0 mmHg
V₂ = 8.2L
1) The set of quantum numbers (4, 2, 1, +1/2) represent this:
a) first quantum number, 4: is the the main quantum number, it represents the main energy level, if it were the last electron of the atom, that means that the electron belonged to an element in the row number 4 of the periodic table, that is one element between the atomic numbers 19 and 36.
b:second quantum number, 2; is the sub-level of energy, it indicates the kinf (shepe) of orbital, the number 2 means that the orbital is type d.
c. third quantum number, 1: it represents the orientation of the orbital in the space.
d. fourth quantum number, +1/2: it is the spin quantum number, given that two electrons in an atom cannot have the same set of four quantum numbers and two electrons can share the same orbital, when one electron has spin +1/2 the other electron in the same orbital has opposite spin (- 1/2).
2) Set of quantum numbers (4, 1, 1, +1/2).
This electron is in the same main energy level than the previous one (4), but it is in a p orbital (second quantum number = 1), instead of a d orbital, and the orientation is px (third quantum number = 1). The spin is +1/2 the same as the other electron.

...Diamond is the best conductor of heat, but heat also transmits readily through many other substances. Do you have multiple choice?
Answer: 1) 1.6 moles of HCl
2) 7.0 moles of HCl
3) 2.4 moles of hydrogen
4) 0.96 moles of HCl
Explanation:
The balanced chemical equation is:
According to stoichiometry :
1 mole of require = 2 moles of
0.8 moles of will require= of
3.5 moles of will require= of
According to stoichiometry :
2 moles of produce = 1 mole of
4.8 moles of will require= of
According to stoichiometry :
1 mole of are produced by = 2 moles of
0.48 moles of are produced by = of
