Directions Now that the lab is complete, it is time to write your lab report. The purpose of this guide is to help you write a c

lear and concise report that summarizes the lab you have just completed. The lab report is composed of three sections: Section I: Experimental Overview o Provide background information. o Include the hypothesis. o Summarize the procedure. Section II: Data and Analysis o Include graphs to display trends in the data. o Identify trends in the data. Section III: Conclusions o Identify if the hypothesis was supported or refuted. o Provide logical reasoning based on data. o Explain how the experiment could be improved. To help you write your lab report, you will first answer the eight questions listed below based on the experiment that you have just completed. Then you will use the answers to these questions to write the lab report that you will turn in to your teacher. You can upload your completed report with the upload tool in formats such as OpenOffice.org, Microsoft Word, or PDF. Alternatively, your teacher may ask you to turn in a paper copy of your report or use a web-based writing tool. Questions Section I: Experimental Overview 1. What is the purpose of the lab? 2. What is your hypothesis for this experiment? 3. What methods are you using to test this hypothesis? Outline the steps of the procedure in full sentences. Section II: Data and Analysis 4. What graphs would clearly represent the trends in your data? Your Student Guide includes information on which graphs to construct. Each graph should have the following items: a. An appropriate title b. Appropriate labels for each axis c. An appropriate scale for each axis d. The correct units for the data Complete a rough sketch of each graph. 5. What do the data in your graphs tell you? Explain in one or two sentences what trend is shown in each of your graphs. Section III: Conclusions 6. What do the data tell you about your hypothesis
Lab:Absorption and Radiation by Land and Water

6. According to Crystal Field Theory, what should be the color of an aqueous solution of the ion [Y(H2O)6]3
UkoKoshka [18]

Answer:

Colourless

Explanation:

We know that Y^3+ has the electronic configuration of;

1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 (the 5s and 4d levels are empty).

According to the crystal field theory, the colour of complexes result from transitions between incompletely filled d orbitals.

As a result of this, complexes with empty or completely filled d orbitals are colourless. Thus,  [Y(H2O)6]3 is colourless according to the Crystal Field Theory.

If 22.5L of nitrogen at 748 mm Hg are compressed to 725 mm Hg at constant temperature. What is the new volume?2.A gas with a vol
kykrilka [37]

Answer:

a)23.2 L

b)68.3kPa

c)7.5 atm

d)60.5L

e)1.67 atm

Explanation:

From Boyle's law:

P1V1=P2V2

P1= 748mmHg

P2=725mmHg

V1= 22.5L

V2??

V2= P1V1/P2= 748×22.5/725= 23.2 L

b)

V1=4.0L

P1= 205×10^3Pa

V2= 12.0L

P2=???

P2= P1V1/V2= 205×10^3×4/12

P2= 68.3×10^3 Pa or 68.3kPa

c)

P1= 1 atm

V1= 196.0L

P2= ??

V2= 26.0L

P2= P1V1/V2=1×196.0/26.0

P2= 7.5 atm

d)

V1= 40.0L

P1= 12.7×10^3Pa

V2=???

P2= 8.4×103Pa

V2= P1V1/P2= 12.7×10^3×40.0/8.4×103

V2=60.5L

e)

V1= 100mL

P1= 1atm

V2= 60mL

P2=???

P2= P1V1/V2= 1×100/60

P2= 1.67 atm
