Question 11 (0.4 points) Ms. Chambers students were in science lab trying to identify standard biomolecules: carbohydrates, fats and proteins. During the lab experience, Assistant Principal Matthews came in to evaluate their teacher and the learning environment. Ms. Matthews reacted positively to the fact that the students were conducting a hands-in investigation, but she reacted negatively to the overall classroom environment. Take a look at one lab group. Justify Ms. Matthews concern. What is something Ms. Chambers should have done before the lab began?
Question 11 options:

Ms. Chambers should have provided the appropriate lab gear. Although the students have on lab aprons and goggles, they are not wearing gloves.

Before beginning the lab, Ms. Chambers should have cleared away all debris and non-required materials. The best way to prevent accidents is to eliminate hazards.

Ms. Chambers should have checked each student group before letting them begin work. Two students in this photo should modify their appearance to maximize safety.

Ms. Chambers should consider what is appropriate for the students to be wearing. In stead of lab aprons, it would be best if the students wore lab coats as well as gloves.
Question 12 (0.4 points)

Study the graph above concerning the extinction rate of animal species compared with the human population growth.

What does this graph suggest about the extinction rate compared to the growth of the human population?
Question 12 options:

Human population is growing as well as animal extinction rate.

Human population is decreasing as well as animal extinction rate.

Human population is growing and animal extinction rate is declining.

Human population is decreasing and animal extinction rate is increasing.

Ineed someone to see if my answers are correct! if any are wrong let me know what the correct answers would be and how to get that answer! 1. how many moles of sodium chloride are in 28 grams od nacl? a. 265 mole naclb. 856 mole naclc. 479 mole of nacld. 1.2 mole nacl < my choice2. 734 grams of lithium sulfate (li2so4) are dissolved to make 2500 ml of solution what is rhe molaratiy? a. 2.67 mb. 4.56 mc. 3.89 m < my choiced. 1.78 m3. how many grams of cacl2 would be dissolved in 3.0 l of a 0.50 m solution of cacl2? a. 250 g cacl2 b. 166.5 g cacl2c. 113.65 g cacl2d. 98 g cacl2 < my choice4. suppose you had 58.44 g of nacl and you dissolved it in exactly 2.00 liters. the molarity if the solution would be 0.5 mtrue < my choicefalse 5. i would need 22g of naoh to make a 3.0 m solution using 250 ml of solvent. true < my choicefalse6. identify the solute: you have a .0195 m solution made from using 6.5 g of solute and 3 l of solvent. identify the solute by solving for molar weight. a. the solute is nacl because the molar weight is 58.43 g/mol < my choiceb. the solute is h2so4 because the molar weight is 98.06 g/molc. the solute is cacl2 because the molar weight is 111.11 g/mol
