Measuring Physical Properties Lab Report Instructions: In the Physical Properties lab, you will test the physical properties of

different building materials in order to pick the appropriate materials for a new home in Tiny World. Record your observations and test measurements in the lab report below. You will submit your completed report. Name and Title: , instructor's name, Sep 9th, measuring physical properties lab report. Hypothesis: In this section, include the if/then statements you developed during your lab activity. These statements reflect your predicted outcomes for the experiment. If we use Aluminum to build the roof of the house, then the temperature inside the house will remain cooler. If we use Clay brick to build the walls and floors of the house, then the temperature inside the house will remain cooler. If we use copper to bring electricity into the home, then it will allow electricity to flow into the home at a faster rate. If we use Iron to construct the latches on the windows and doors, then the magnetism will keep the latches secure. Procedure: The materials and procedures are listed in your virtual lab. You do not need to repeat them here. However, you should note if you experienced any errors or other factors that might affect your outcome. Using the summary questions, clearly define the dependent and independent variables of the experiment. Independent V- The type of material tested. dependent V- The results of each test completed Objective(s): In your own words, what was the purpose of this lab? Conclusion: Your conclusion will include a summary of the lab results and an interpretation of the results. Please answer all questions in complete sentences using your own words. 1. Using two to three sentences, summarize what you investigated and observed in this lab. 2. What building material did you use to build your house? Did your results support or fail to support your hypotheses? 3. What were the densities of the materials you chose for the walls and floor for the home in Tiny World? Why do you think a building material's density is important when building homes or architectural structures? 4. Why wouldn’t you choose wood or aluminum for the latches on your house? 5. Which material has the highest thermal conductivity? Which material has the highest electrical conductivity? Explain why thermal and electrical conductivity is so high with this material. 6. Think about where you live now or where you have lived in the past; use complete sentences to describe this environment and the weather. What building materials do you believe would work well to build a home in that area? Explain why you chose these materials. P.S. Answer objections and conclusion.

What occurs as two atoms of fluorine combine to become a molecule of fluorine?
algol [13]
When two atoms of Florine combines, they share an electron pair to complete it's octet. This result is formation of single bond between two fluorine atoms. This process is exothermic in nature, and hence, heat is liberated during the process of bond formation.  <span />

What is the slope of the line?
pychu [463]

Answer:

The slope of the line is -\frac{10}{7}.

Explanation:

The slope of the line (m) is the change in dependent variable (y) divided by the change in independent variable (x):

m = \frac{y_{f}-y_{o}}{x_{f}-x_{o}} (1)

If we know that (x_{o}, y_{o}) = (0, 2) and (x_{f}, y_{f}) = (1.4, 0), then the slope of the line is:

m = \frac{0-2}{1.4-0}

m = -\frac{10}{7}

The slope of the line is -\frac{10}{7}.

A. Based on the activation energies and frequency factors, rank the following reactions from fastest to slowest reaction rate, a
deff fn [24]

Answer:

A) E_{a} = 350KJ/mol, E_{a} = 50KJ/mol, E_{a} = 50KJ/mol

     A = 1.5×10^{-7}s^{-1}, A = 1.9×10^{-7} s^{-1}, A=1.5×10^{-7} s^{-1}

B) 4.469

Explanation:

From Arrhenius equation

      K=Ae^{\frac{E_{a} }{RT} }

where; K = Rate of constant

            A = Pre exponetial factor

            E_{a} = Activation Energy

             R = Universal constant

             T = Temperature in Kelvin

Given parameters:

E_{a} =165KJ/mol

T_{1}=505K

T_{2}=525K

R=8.314JK^{-1}mol^{-1}

taking logarithm on both sides of the equation we have;

InK=InA-\frac{E_{a} }{RT}

since we have the rate of two different temperature the equation can be derived as:

In(\frac{K_{2} }{K_{1} } )=\frac{E_{a} }{R}(\frac{1}{T_{1} } -\frac{1}{T_{2} } )

In(\frac{K_{2} }{K_{1} } )=\frac{165000J/mol}{8.314JK^{-1}mol^{-1}  }.(\frac{1}{505} -\frac{1}{525} )

In(\frac{K_{2} }{K_{1} } )= 19846.04×7.544×10^{-5} = 1.497

\frac{K_{2} }{K_{1} } =e^{1.497} = 4.469
