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 clear and concise report that summarizes the lab you have just completed.
The lab report is composed of four sections:
Section I: 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
• Identify if the hypothesis(es) was (were) supported or refuted.
• Provide logical reasoning based on data.
• Explain how the experiment could be improved.

To help you write your lab report, you will first answer the questions listed below by reflecting on the experiment you have just completed. Then you will use the answers to these questions to write the lab report that you will turn into 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.

Answer:

Cl2 acts as an oxidizing agent

Explanation:

The balanced equation is

Cl2+NaOH⟶NaCl+NaClO3+H2O

Cl2 acts as a reactant in this chemical reaction

Cl2 receives one electron and thus reduces itself from Cl2 to 2 Cl−. This indicates that 2Cl- will oxidize some other element and hence Cl2 act as an   oxidizing agent.

The true statement about the Moon is: A. The Moon is always moving around Earth in a circle.

A Moon can be defined as the natural satellite of planet Earth that shines due to the Sun's reflected light, as it revolves around the Earth from west to east in 29½ days.

Generally, there are four (4) primary Moon phases and these are:

Answer:

N₂

Explanation:

Sodium is a larger molecule with a much higher molecular weight. However, 20g of N₂ would be a smaller amount of molecules than 20g of sodium due to how there are multiple nitrogen molecules.

2/3 * given mass of N₂ = mass of N₃

N₃ (Azide ion) given mass = 20g

Na = 20g

Masses of chemicals are equal

Na = 22.990g/mol

20g/22.990g/mol = 0.8699mol of Na

N₃ = 20g

N₃ = N g/mol x 3

N = 14.007 g/mol

14.007 x 3 = 42.021 g/mol

N₃ = 42.021g/mol

20g/42.021g/mol = 0.4759 mol of N₃

Notice how there are fewer moles of the Azide ion than the Sodium.

0.4759 moles of NaN₃ is produced

combine molecular weights:

42.021 + 22.990 = 65.011 g/mol

multiply by amount of moles of the limiting reactant:

0.4759 mol *65.011 = 30.942 g

Also, here is the balanced equation:

3N₂ + 2Na = 2NaN₃

The results are the same as the balanced equation.

The correct answer is - discovering or diagnosing the disease.

Explanation:

According to the question, this technology includes genetically modifying a common virus in order to destroy or kill the deadly brain tumor without affecting normal cells around the tumor, this technique is genetic engineering.

This technique can help in treating or curing the disease by killing the tumor cells and make them non-lethal. It can also prevent the tumor cells to grow and make them controlled. There is nothing mention related to diagnosing the disease in the question and it is not possible to find this tumor with help of such a technique.

Answer:

Kc ≅ 100 (1 sig. fig.)

Explanation:

              2NH₃(g)       ⇄      N₂(g)   +   3H₂(g)

C(i)         3.00 mol/L             0                0

ΔC             -2x                       +x              +3x

C(eq)     0.600 mol/L            x                3x

3.00 - 2x = 0.600  =>  x = 3.00 - 0.600/2 = 1.2 mole/L

At equilibrium Kc = [N₂][H₂]³/[NH₃]² = (x)(3x)³/(3·1.2)² = (1.2)(3.6)³/(0.600)² = 155.52 (calculator)

Rounds to 1 sig. fig. based on given 3.00 moles NH₃(g)' Kc ≅ 100.

Answer:

solid=(s)

Explanation:

A solubility table may be something your class may want you to memorize. Where an aqueous (aq) solution is formed by a soluble compound dissolving in water, our solvent. So if we refer to this solubility table, it says phosphate (PO4) is usually insoluble, so in the reaction it won't break down in water and will stay as a solid (s). The only exceptions are group 1 alkali metals or ammonium (NH4+).

Answer:

[H2] = [I2] = 0.64M; [HI] = 4.72M

Explanation:

Based on the reaction:

H2 + I2 ⇄ 2HI

The K is defined as:

k = 54.3 = [HI]² / [H2] [I2]

Where [] is molar concentration of each reactant at equilibrium

As the initial concentration of HI is 6mol/dm^3 = 6M the equilibrium concentration of each reactant is:

[H2] = X

[I2] = X

[HI] = 6 - 2X

Where X is reaction coordinate

Replacing:

54.3 = [6-2X]² / [X] [X]

54.3X² = 4X² - 24X + 36

0 = -50.3X² - 24X + 36

Solving for X:

X = -1.12. False solution, produce negative concentrations

X = 0.64M. Right solution

Replacing:

[H2] = 0.64M

[I2] = 0.64M

[HI] = 6 - 2*0.64M = 4.72M

Equilibrium concentrations are:

Answer: 15 L of [tex]N_2[/tex] gas will have same numer of molecules as 15L of [tex]CO_2[/tex] gas at the same temperature and pressure,

Explanation:

According to avogadro's law, equal moles of gases occupy equal volume at same conditions of temperature and pressure.

[tex]\text{Number of moles}=\frac{\text{Given volume}}{\text{Molar volume}}[/tex]

[tex]\text{Number of moles of} CO_2=\frac{15L}{22.4L/mol}=0.67mol[/tex]

[tex]1 mole of CO_2[/tex] contains=[tex]6.022\times 10^{23}[/tex]  molecules of [tex]CO_2[/tex]  

Thus 0.67 moles of [tex]CO_2[/tex] contains=[tex]\frac{6.022\times 10^{23}}{1}\times 0.67=4.03\times 10^{23}[/tex] molecules

Now molecules of [tex]N_2[/tex] = molecules of [tex]CO_2[/tex] = [tex]4.03\times 10^{23}[/tex]

[tex]6.023\times 10^{23}[/tex] molecules of [tex]N_2[/tex]  = 22.4 L

Now [tex]4.03\times 10^{23}[/tex]  molecules of [tex]N_2[/tex] = [tex]\frac{22.4}{6.023\times 10^{23}}\times 4.03\times 10^{23}=15L[/tex]

pH = 1.522

Explanation:

HCl + H20 -> Cl^(-) + H30^(+)

0.03M ____ ____

____ 0.03M 0.03M

[H30^(+)] = 0.03M

pH = - log([H30^(+)])

pH = - log( 0.03)

pH = 2 - log3

pH = 2- 0.47

pH = 1.522

The pH of the hydrogen chloride, HCl solution having a concentration of 0.03 M is 1.52

This is simply a measure of the acidity / alkalinity of a solution.

The pH measures the hydrogen ion concentration while the pOH measures the hydroxide ion concentration

Dissociation equation

HCl(aq) —> H⁺(aq) + Cl¯(aq)

From the balanced equation above,

1 mole of HCl contains 1 mole of H⁺.

Therefore,

0.03 M HCl will also contain 0.03 M H⁺

pH = –Log H⁺

pH = –Log 0.03

pH = 1.52

Answer:

23.8g

Explanation :

Convert 2.0M into mol using mol= concentration x volume

2.0M x 0.1L (convert 100mL to L since the units for M is mol/L)

= 0.2 mol

We can now find grams by using the molar mass of KBr

=119.023 g/mol (Found online) webqc.org

but can be be calculated by using the molecular weight of K and Br found on the periodic table

We can now calculate the grams by using grams=mol x molar mass

119.023g/mol x 0.2mol

= 23.8046 g

=23.8g (rounded to 1decimal place)
