3) orbitals can hold two electrons provided they are spinning in the same direction

We define an orbital in chemistry as a region in space where there is a high probability of finding an electron.

Each orbital holds a maximum of two electrons which spin in opposite direction according to Pauli exclusion principle.

According to this principle no two electrons can have the same set of quantum numbers. As a result, the spin quantum numbers of two electrons in the same orbital must differ hence they spin in opposite directions.

3) is the incorrect statement. Electrons must pair with opposite spins since they are both negatively charged and would therefore repel each other.

Find the volume of a gas if 3.6 mols of the gas is at STP

Digiron [165]

Answer:

81 L gas

General Formulas and Concepts:

<u>Ideal Gas Law</u>

STP (Standard Conditions for Temperature and Pressure) = 22.4 L per mole at 1 atm, 273 K

<u>Stoichiometry</u>

Using Dimensional Analysis

Explanation:

<u>Step 1: Define</u>

[Given] 3.6 mols gas at STP

[Solve] volume (L) of gas

<u>Step 2: Convert</u>

[DA] Set up: $\displaystyle 3.6 \ mol \ gas(\frac{22.4 \ L \ gas}{1 \ mol \ gas \ at \ STP})$
[DA] Multiply [Cancel out units]: $\displaystyle 80.64 \ L \ gas$

<u>Step 3: Check</u>

<em>Follow sig fig rules and round. We are given 2 sig figs.</em>

80.64 L gas ≈ 81 L gas

A student performs an experiment to determine the melting point of ice in order to investigate the strength of electrostatic for

andrezito [222]

Once the student has finished his experiment, additional steps he may take are to analyze the data gathered and draw a conclusion, then publish his findings to be seen by his peers (other students).

<h3 /><h3>What comes after the experiment?</h3>

Once an experiment is concluded, one must go over the data gathered.
By this, we mean to analyze the information obtained through the experiment.
This allows the student to draw a conclusion backed by evidence.
Once complete, it is wise to share and discuss the findings with peers.

Therefore, we can confirm that once the experiment is completed, the most common action that follows is to draw a conclusion based on the analysis of the data gathered during the experiment, then discuss the findings with peers.
