LAB 1 1. Describe the function of the following pieces of safety equipment and how each might be used: (10 points) a. Eye Wash (2 points) In the event of a chemical splash to the eyes, flood the eyes for at least 15-30 minutes with water. Flush from the eye outward. If you were not wearing proper eye wear, a chemical could splash into your eye and would make it necessary to use this. b. Fire Blanket (2 points) Used in order to put out a small fire. If a small area of the lab caught fire, a fire blanket could be used to put it out. c. Shower (2 points) Safety showers are designed to flood your body with water in the event of a fire or chemical spill. Stand under and activate the shower for at least 15-30 minutes. If a …show more content…
When this slide is done being used it should be discarded in the biological hazards materials container. 3. Metric Measurements: Perform each of the following conversions. (24 points) a. Given that one inch = 2.54 cm. State the student's height in inches and then convert to centimeters. (4 points) 66 inches. 167.64 cm. b. The width of a normal sheet of paper is 8.5 inches. Convert this length to kilometers. (4 points) 0.0002159 km. c. A lab exercise in BIO156 required 300 ml of water that was poured from a two-liter container. How many milliliters were left in the original container? (4 points) 1,700 ml. d. A typical can of soda is 355 ml. How many liters are there in this can of soda? (4 points) .355 liters. e. The weight of a small bag of sugar is 2.265 kg. The student is baking cakes for a college scholarship fundraiser. It takes 100 grams of sugar to make one small cake. How many cakes can be made from a single bag of sugar? (4 points) 22 cakes. f. The student is conducting a nutrition experiment using lab rats. One group (control group) is fed a normal diet, while the other group (experimental group) is fed a diet high in protein. There were 30 rats total used in the experiment. At the end of the experiment, the average mass (weight) of a rat in the control group was 60.4 g while the average mass (weight) of a rat in the experimental group was 0.0689 kg. What is the average difference in weight between the two groups in grams?
The eyewash fountain is used to rinse chemical splashes off the eyes. They are used by rinsing the eyes 15 to 30 minutes with water.
Cellular respiration: C6H12O6 + 6O2 → 6CO2 + 6 H2O + 36 or 38 ATP
3. State the name and structure of the functional group for each type of biologically
9. How many moles of NaOH would be needed to completely react with all of the excess HCl determined in problem 8?
3. Of the substances that diffused through the bag, did all of the molecules diffuse out? About half of the glucose did diffuse through the bag.
3. 3.14 x 1023 molecules of CO2 are produced in a chemical reaction. How much would the sample weigh in grams?
45. You just removed 60,000 grams of 5.56 ammo from the stockpile of 167 kilograms. How manykilograms remain?
Usage of equipment should be monitored constantly and children should be given instructions of how to use it. Equipment should be stored safely and should be checked and maintained regularly. Any damaged equipment should be removed, repaired or made unreachable if its condition creates a risk of hazard.
5. A salvage operator recovered coins believed to be gold. A sample weighed 129.6 g and had a
9. Each of the other solutions is already approximately 0.1 M. With these solutions you can pour a small
Find the average distance of Pluto from the Sun. Using the same scale as Procedure B, calculate the scaled distance that Pluto should be on your model. Show your work! 5,906,376,200 / 25,000,000 = 236.25cm ~ 236 cm
Predict: If the added mass on the lid was 50 kg, a total mass of 60 kg would exert pressure on the gas inside the container. What would be the volume of the gas? __.42 ______________
Step 9: Because we measured the lengths in centimeters rather than meters, we need to calculate are ‘g’ value into m/s2 so we can compare it to the SI unit for acceleration due to gravity. (Eg. 981.4/100 = 9.81 m/s2)
1 litre of water with each meal as well as two other bowls throughout the day so she had access to 5 litres of water. She had around 500 millilitres of water each bowl so she had a total of 2500 millilitres out of 5000 millilitres.
