Answer:

Subject of the experiment and out of scope

Explanation:

In any research study, the process of thing studied is basically the subject of the experiment on which research is conducted to determine the outcomes. If any thing lies out of the experimental process reach, then it is said to be out of scope of the experiment.

Whitney's tidal volume, which is the volume of air that she inhales and exhales, was 0.56 L . Her tidal volume was measured at a

ipn [44]

<u>Given:</u>

Volume of air inhaled V = 0.56 L

Temperature T = 37 C = 37 +273 = 310 K

Pressure P = 744 mmHg = 744/760 = 0.979 atm

% N2 in air = 78%

<u>To determine:</u>

The moles of N2 inhaled in one breath

<u>Explanation:</u>

Step 1: Calculate the moles of air inhales

Based on the ideal gas law:

PV = nRT

where P = pressure, T = temperature, V = volume, n = # moles

R = gas constant = 0.0821 L atm/mol-K

n = PV/RT = 0.979 * 0.56/0.0821*310 = 0.0215 moles of air

Step 2: Calculate the moles of N2

It is given that air contains 78% N2

Therefore:

moles of N2 = 0.0215 * 78/100 = 0.0168 moles

Ans: moles of N2 = 0.0168

Three carbon atoms are linked by single covalent bonds such that they form the shape of a V. All of the unshared electrons form

Nostrana [21]

Answer:

C) 8

Explanation:

Total number of carbon atoms = 3

Number of single bonds = 3

So, each carbon is bonded to the next carbon with the single bond, Number of unshared electrons left with the terminate carbons are 3 and with the intermediate carbon is 2.

Thus, the two terminate carbon have 3 hydrogen each and the intermediate will have 2.

<u>Total - 8</u>

Describe the Self-Consistent Field (SCF) method for obtaining the orbitals of a Boron atom

weqwewe [10]

<h3>What is Self-Consistent Field (SCF)?</h3>

This is used in quantum chemical models to accurately calculate the amount

of orbitals present in an element.

The Self-Consistent Field (SCF) method for obtaining the orbitals of a

Boron atom involves the following processes which include:

Selecting an approximate Hamiltonian

Solving the Schrödinger equation to obtain a more accurate set of orbitals.
Solving the Schrödinger equation again until the results converge.

The converging of the result typically signified the end of the solving of the

equations and the derivation of the orbitals of the Boron atom.

<span><span>The Lysosome organelles <span> have several dozen of enzymes in each one.</span>
</span><span> The word "Lysosome" comes from two Greek words. One, "Lysis" meaning destruction and two, "Soma" meaning body
</span><span>There is really no way for a lysosome organelle to malfunction execpt if the cell starts eating to much and there are not enough lysosomes to digest all of the food. Which leeds up to the cell not being able to eat anymore.</span></span>
