The mantle layer is more dense closest to the core.
Answer:
92.6 kJ.
Explanation:
<em>∵ ΔG°rxn = - nFE°cell,</em>
Where, ΔG°rxn is the standard free energy change (J).
n is the no. of electrons in the reaction (n =2).
F is Faraday constant (C/mol) (F = 96500 C/mol).
E°cell is the standard cell potential (E°cell = - 0.48 V).
<em>∴ ΔG°rxn = - nFE°cell </em>= - (2)(96500 C/mol)(- 0.48 V) = <em>92640 J = 92.64 kJ.</em>
Answer: 1.11 atm
Explanation:
The unit of pressure include kilopascal (kPa), atmospheres (atm), mmHg etc
Now, given that:
Air pressure = 113 KPa
Convert kPa to atm
If 101.325 kPa = 1 atm
113 kPa = Z atm
To get the value of Z, cross multiply
Z atm x 101.325 kPa = 1 atm x 113 kPa
Z = ( 1 atm x 113 kPa) / 101.325 kPa
Z = 1.11 atm
Thus, the pressure is 1.11 atm
The answer I'm pretty sure is a because it can't be d because ionic binding the electrons are affected and it can't be c because that's covalent bonding and it can't be b because they don't swap electrons.
Answer:
Absorb light energy
Explanation:
Chlorophyll absorbs light energy which is used to produce carbohydrate and oxygen in the presence of carbon dioxide and water.
