Hello there!

I am not really sure which part you are talking about but let me answer some of them.

First, you need to read the information they gave you about glucose etc..

13- What is produced in photosynthesis?
"Photosynthesis is essential for all life on earth, because it provides food and oxygen."

Thus, the answer is: Photosynthesis produced food and oxygen.

14- What is the glucose used for?
"The glucose produced is used by the plant for energy and growth."

Thus, the answer is: The glucose used for energy and growth of the plants.

15- What is the oxygen used for?
"The oxygen produced is released into the air for us to breath."

Thus, the answer is: The oxygen used for us to breath.


I hope this helps!

Let me know if you have questions about the answer.

Answer:

1.) Eyewash station --> D

2.) Absorbent material --> G

3.) Fire extinguisher --> F

4.) Safety Shower --> E

5.) Biohazard container --> J

6.) Broken glass container --> I

7.) Safety goggles --> C

8.) Lab apron --> H

9.) asbestos gloves --> A

10.) Latex gloves --> B

Explanation:

In an equipped laboratory, alot of safety equipments are made available and kept in area that it could be easily accessed in the laboratory. Safety or protective equipments are those materials that helps protect a laboratory personnel while at work on the lab.

These equipments include:

--> Eyewash station: This is an equipment used in the laboratory during emergency to rinse chemical from the eye. Therefore option D is correct.

--> Absorbent material: They are used to contain small spills in the laboratory. Therefore option G is correct.

--> Fire extinguisher: This equipment is used to put out small fires. Therefore F is correct.

--> Safety Shower: This is used to rinse away chemical from clothes and on skin during emergency. Therefore option E is correct.

--> Biohazard container: This container is used to safely dispose bacteria culture, blood and other living tissues. Therefore option J is correct.

--> Broken glass container: This is used to dispose cracked, chipped or broken bottle in the laboratory. Therefore option I is correct.

--> Safety goggles: This helps to protect the eye from chemical and broken glasses. Therefore option C is correct.

--> Lab apron: This is worn by the laboratory personnel to help protect the skin from chemical and biohazards. Therefore option H is correct.

--> Asbestos gloves: these are heat resistant gloves used to protect the hands from heat. Therefore option A is correct.

--> Latex gloves: these are equally worn by the laboratory personnel to protect the hands from chemicals and biohazards

Experiment #1A melting point of an old sample of Naphthalene was completed and a melting range of 77-83 oC was observed and reco
White raven [17]

Answer:

%error = 0.32%

Explanation:

Let's answer both questions, by parts.

1. Percentage error:

In this case, I do not have the video, but I do have the reported melting point of naphtalene which is 80.26 °C.

The expression to calculate the percentage error is the following:

%Error = absolute error / actual percentage. (1)

And the absolute error is:

Abs error = actual value - experimental value  (2)

But the experimental value is a range, so we just have to get a average of that:

Exp value = 77 + 83 / 2 = 80 °C

Now the absolute error:

Abs error = 80.26 - 80 = 0.26 °C

Finally the %error:

%error = (0.26 / 80.26) * 100

<h2>%error = 0.32%</h2>

2. Meaning of melting point range and %error

The melting point range just means that the sample of naphtalene has impurities, and when a sample of any compound has impurities, melting point tends to be low. However, this decrease of temperature is a wider range. But usually a range of just 5° C means that compound has little traces of impurities but it can still be used for reactions.

The %error means that the impurities of the sample are really low, so the sample is practically pure with little traces of impurities.
