Leaf stomates are the primary sites of transpiration and consist of two guard cells that form a small pore on the surfaces of leaves. The guard cells control the opening and closing of the stomates in response to various environmental stimuli and can regulate the rate of transpiration to reduce water loss.
An assessment finding which the nurse should document as evidence of a positive response of this infant client to oxygen therapy is decreased agitation and restlessness.

The classification of each of the elements into nonessential element, essential bulk element, or essential trace element are as follows:
Nonessential elements:
Essential bulk elements:
- Carbon,
- Nitrogen,
- Calcium,
- Hydrogen
Essential trace elements:
The complete question
The elements are: Hydrogen, iron, Copper, Nitrogen, Helium, Carbon, Aluminum, Calcium, Argon
<h3>What is Essential and Nonessential Elements?</h3>
Nonessential elements as the name implies are elements which are not necessary for the functional routine of the body and hence are not included in diets.
Essential bulk elements are elements which are needed for the proper functioning of the body and hence are required in relatively large amounts.
Essential trace elements are required in minute quantities in the body.

Answer:
B. CH₅N
Explanation:
The combustion reaction of a compound CₐHₓNₙ with O₂ is:
CₐHₓNₙ + O₂ → a CO₂ + X/2 H₂O + n NO₂
Where 1 mole of CₐHₓNₙ with an excess of O₂ produce a moles of CO₂, X/2 moles of H₂O and n moles of NO₂
Thus, you need to convert the mass of CO₂ and H₂O to moles to find the C:H ratio and determine a possible empirical formula thus:
Moles CO₂ (Molar mass 44g/mol):
44g ₓ (1mol / 44g) = 1 mole CO₂ = 1 mole C
Mole of H₂O (Molar mass 18g/mol):
45g ₓ (1 mol / 18g) = 2.5 moles H₂O = 5 moles H
Thus, in the compound you have 5 moles of H per mole of C, and a possible empirical formula is:
B. CH₅N
The only structure that meet this C:H ratio
