ASAP! —Will Give Brainliest!Now that the lab is complete, it is time to write your lab report. The purpose of this guide is to h

elp you write a
clear and concise report that summarizes the lab you have just completed.
The lab report is composed of four sections:
Section 1: Experimental Overview

- Provide background information
- Include the hypothesis(es).

Summarize the procedures.
Section II: Data and Observations

- Summarize the data you collected in the lab guide.
Include information from data tables
- Include any written observations that are relevant.

Section III: Analysis and Discussion

- Discuss any important calculations or formulas used.
- identify key results, what the results indicate, and any trends in the data.
- Include graphs (if constructed) that display trends in the data.
- Provide possible reasons for any problems with the experiment, or unexpected data.

Section IV: Conclusions
o identify if the hypothesis(es) was (were) supported or refuted

- Provide logical reasoning based on data.
- Explain how the experiment could be improved.

Questions I have not answered yet. Please help me out:

-What do the key results indicate?

- If you constructed graphs, what trends do they indicate in your data?

-Were there any problems with the experiment or the methods? Did you have any surprising results?

- What do the results tell you about your hypothesis?

- How does the data support your claim above?

To break the oxygen-oxygen bonds in a single O2 molecule, 1 × 10–18 J of energy is required. Which of the following wavelengths
Sonbull [250]

E = hc/(lamda)

The lamda symbol is wavelength, which this site does not have. I can represent it with an "x" instead.

Plancks constant, h = 6.626×10^-32 J·s

Speed of light, c = 3.00×10^8 m/s

The energy must be greater than or equal to 1×10^-18 J

1×10^-18 J ≤ (6.626×10^-32 J·s)*(3.0×10^8 m/s) / x

x ≤ (6.626×10^-32 J·s)*(3.0×10^8 m/s) / (1×10^-18 J)

x ≤ 1.99×10^-7 m or 199 nm

The wavelength of light must be greater than or equal to 199 nm

Two atoms that are isotopes of one another must have the same number of what? Electrons, All Particles, Protons, or Neutrons
emmainna [20.7K]

atoms are made of 3 types of sub atomic particles; neutrons, protons and electrons

atomic number is the number of protons which is characteristic for the element. Atoms of the same element have the same number of protons.

mass number is the sum of the neutrons and protons.

Isotopes are atoms of the same element with different mass numbers. since they are the same element number of protons are the same but number of neutrons vary.

therefore 2 isotopes are of the same element so they have the same number of protons.

Under which conditions do you expect helium gas to deviate most from ideal behavior?. . a. 100 K and 1 atm. b. 300 K and 2 atm.
mamaluj [8]
Ideal behavior is approached by gases when the conditions of the system are at a low pressure and high temperatures. Therefore, the correct answer is C. At the conditions of lowest temperature highest pressure, gases will deviate from an ideal gas.

A molecular orbital that decreases the electron density between two nuclei is said to be ____.
nikklg [1K]

A molecular orbital that decreases the electron density between two nuclei is said to be <u>antibonding.</u>

The bonding orbital, which would be more stable and encourages the bonding of the two H atoms into H_{2}, is the orbital that is located in a less energetic state than just the electron shells of the separate atoms. The antibonding orbital, which has higher energy but is less stable, resists bonding when it is occupied.

An asterisk (sigma*) is placed next to the corresponding kind of molecular orbital to indicate an antibonding orbital. The antibonding orbital known as * would be connected to sigma orbitals, as well as antibonding pi orbitals are known as \pi* orbitals.

Therefore,  molecular orbital that decreases the electron density between two nuclei is said to be <u>antibonding.</u>

<u></u>

Hence, the correct answer will be option (b)
