Answer:
Radioactive dating
Explanation:
Radioactive dating measures the ratio of C¹²(normal) and C¹⁴ (radioactive) in fossils to determine the exact age of the specimen. C¹⁴ is unstable and has a half life of 5730 years, so as the organism ages the amount of C¹⁴ diminishes but the amount of C¹² remains constant. The ratio of C¹⁴ to C¹² is used to analyze the decay of atomic particles to determine exact age.
Answer:
They have been found to cause cancer in humans meaning any release of carcinogens will increase, not decrease, CANCER RISK.
Explanation:
Certain chemicals, including benzene, beryllium, asbestos, vinyl chloride, and arsenic are known human carcinogens, meaning “they have been found to cause cancer in humans.” A persons risk of developing cancer depends on how much, how long, how often, and when they are exposed to these chemicals.
<u>Answer:</u> The amount of p-toluidine hydrochloride contained is 2.4 moles.
<u>Explanation:</u>
To calculate the number of moles for given molarity, we use the equation:
Molarity of p-toluidine hydrochloride solution = 0.167 M
Volume of solution = 70. mL
Putting values in equation 1, we get:
Hence, the amount of p-toluidine hydrochloride contained is 2.4 moles.
H+ ions are proton charged ions that are present
A is the answer
Venn diagrams are used for comparing and contrasting different topics. The overlapping sections show characteristics that the topics have in common, and the sections that are unique to each topic show the characteristics apply to only that topic.
