You haven't provided any of the answer choices, but it is likely that a Rainforest biome is the answer to your question.
Answer:
According to the subshells, the ns subshell has a sphere-like shape, and on average, lower energy than the rest of the subshells on the same quantum level
The np subshell has two lobes opposite the origin, and on average has more energy than a ns subshell since it has one more angular node, and thus np electrons are less core-like (and further away from the nucleus).
n
d orbitals have five spatial orientations:
and n
f orbitals have seven spatial orientations
The energies are on average in increasing order for the same energy level , n as follows,
nS < nP < nD < nF
1 meter = 1000 mm so 14mm x (1m/1000mm) = .014m
So first, you would take 10 and raise it up to the 14th power. Then take 10, and raise it up to 10th power. After doing all the work, your answer should be 2.336E29.
<u>Given:</u>
Mass of Ag = 1.67 g
Mass of Cl = 2.21 g
Heat evolved = 1.96 kJ
<u>To determine:</u>
The enthalpy of formation of AgCl(s)
<u>Explanation:</u>
The reaction is:
2Ag(s) + Cl2(g) → 2AgCl(s)
Calculate the moles of Ag and Cl from the given masses
Atomic mass of Ag = 108 g/mol
# moles of Ag = 1.67/108 = 0.0155 moles
Atomic mass of Cl = 35 g/mol
# moles of Cl = 2.21/35 = 0.0631 moles
Since moles of Ag << moles of Cl, silver is the limiting reagent.
Based on reaction stoichiometry: # moles of AgCl formed = 0.0155 moles
Enthalpy of formation of AgCl = 1.96 kJ/0.0155 moles = 126.5 kJ/mol
Ans: Formation enthalpy = 126.5 kJ/mol
