Answer: E = - 19.611×
J
Explanation: The lowest possible energy can be calculated using the formula:
where:
Z is atomic number of the atom;
k is a constant which contains other constants and is 2.179× J
n is a layer;
For the lowest possible, n=1.
Atom of Lithium has atomic number of Z=3
Substituing:
J
<u>The energy for the electron in the </u>
<u> ion is - 19.611 joules</u>
Answer:
ΔHr = -86.73 kJ/mol
Explanation:
Using Hess's law, you can calculate ΔH of any reaction using ΔH°f of products and reactants involed in the reaction.
<em>Hess law: ∑nΔH°f products - ∑nΔH°f reactants = ΔHr</em>
<em>-Where n are moles of reaction-</em>
For the reaction:
Fe³⁺(aq) + 3 OH⁻(aq) → Fe(OH)₃(s)
Hess law is:
ΔHr = ΔH°f Fe(OH)₃ - ΔH°f Fe³⁺ - 3×ΔH°f OH⁻
Where:
ΔH°f Fe(OH)₃: −824.25 kJ/mol
ΔH°f Fe³⁺: −47.7 kJ/mol
ΔH°f OH⁻: −229.94 kJ/mol
Replacing:
ΔHr = −824.25 kJ/mol - (−47.7 kJ/mol) - (3×-229.94 kJ/mol)
<em>ΔHr = -86.73 kJ/mol</em>
Answer:
As the garter snake can be found almost in any kind of habitat, what makes them be able to survive in any environment include:
1. They hibernate to increase their chances of survival in unfavorable weather conditions.
2. They can blend with the background of any environment especially grass to escape being eaten.
3. They produce an odor that is usually unpleasant especially when about to be attacked.
Explanation:
The garter snakes are distinguished by the three stripes running the length of their body and can often be found in forests, places that are even close to water bodies, and almost any place, even in holes.
