Answer:
Tissue level of organization
Explanation:
The various levels of the organization of life are as follows:
Cells: a cell is the basic unit of ife
Tissues; A tissue is a group of cells with a common origin. performing similar functions.
Organ: an organ is a group of tissues with varied or similar function that work together to perform a specific function.
System: a system is a group of different organs that work together in the body to perform a specific function.
Since, the leaf is an organ in the plant that performs the function of photosynthesis, the group of dermal cells found on the leaf are in the tissue level of organization, they perform the function of protection for the leaf.
Moles Fe₂O₃ produced : 1.16 moles
<h3>Further explanation</h3>
Given
2.32 moles of iron
Required
moles of Fe2O3
Solution
The reaction coefficient in a chemical equation shows the mole ratio of the reacting compounds (reactants and products)
Reaction
4 Fe + 3 O₂ ⇒ 2 Fe₂O₃
From the equation, mol ratio Fe : mol Fe₂O₃ = 4 : 2, so mol Fe₂O₃ :
= 2/4 x mol Fe
= 2/4 x 2.32
= 1.16 moles

The volume of neon when the pressure is reduced to 93.3 kPa is 519 mL.
Explanation:
The kinetic theory of gases is mostly based on Boyle's law. From the Boyle's law, the pressure experienced by any gas molecules is inversely proportional to volume of the gas molecules. Also this inverse relation is obeyed if and only if the number of moles and temperature of the gas molecules remained constant.
So,
So if there is a change in pressure then there will be inverse change in volume. That means if there is decrease in the pressure of gas molecules then there will be increase in the volume and vice versa.
So the Boyle's law is combined as 
As here the initial pressure or 
is 1 atm or 101.3 kPa and the initial volume is 478 mL. Similarly, the final pressure is 93.3 kPa and the final volume will be
So, the volume of neon when the pressure is reduced to 93.3 kPa is 519 mL.
