Why is it important to be aware of the properties of the chemicals that you use for experiments?

Answers

Answer 1

Since some substances lose their shelf life at high temperatures, it is important to understand the physical and chemical qualities of everyday items in order to store them effectively and prevent  allergies to certain chemicals.

Why is it important to aware properties?Chemical classes can be created using chemical attributes. Additionally, they can be helpful in identifying unidentified chemicals and in separating or purifying them from other substances. Minimizing or removing the factors whose effects we are not accounting for in the experiment. We may quantify the changes caused only by the effects of the variables we are interested in by maintaining them as constants (in your sample question, concentration should be the same, high purity and quality material should be picked to remove the effects of undesired contaminants, etc.).

Which of the following is not a reason why food-borne illness has increased?
A. Modern production methods
B. Increase use of antibiotics in food-source animals
C. Modern distribution methods
D. Lack of adequate regulation

Answers

Answer:

B

Explanation:

I am not sure, however, after evaluating the possible choices I belive this makes most sense. I hope this helps!

It is not accurate to say that food-borne illness has increased due to a "lack of adequate regulation , therefore, the correct answer is D, as adequate regulation would actually help to prevent food-borne illness.

What is Food-borne illness?

Food-borne illness can be caused by a variety of factors, including the presence of harmful microorganisms (such as bacteria or viruses) in food, contamination of food during production or processing, inadequate cooking or storage of food, and poor hygiene practices among food handlers.

While modern production, distribution, and processing methods can potentially contribute to the spread of food-borne illness, adequate regulation can help to mitigate these risks. Regulations can require food producers and processors to implement food safety measures, such as regular testing for pathogens and proper sanitation practices.

Hence, It is not accurate to say that food-borne illness has increased due to a "lack of adequate regulation , therefore, the correct answer is D.
