Week 6 Lab: Nuclear Chemistry Objectives: • Identify the differences between chemical reactions and nuclear reactions. • Identify the concept of radioactive decay. • Identify the nuclear changes associated with alpha, beta or gamma decay. • Write the products of nuclear reactions involving alpha, beta or gamma emissions. • Explain the concept of half-lives and complete half-life calculations. • Identify common subatomic particles and energies involved in nuclear reactions • ...

Q1: In calculating the size of Earth, Eratosthenes used assumption or knowledge that: Select one: a. Earth is a sphere b. Sun is far away, so that sun rays reach Earth in parallel c. Sun shone directly above a deep well d. Sun cast a slight shadow at some distance from the deep well e. All of the above correct answers e. All of the above Q1: There were multiple estimates for the age of Earth. They include: Select one: a. The age is about 6000 years according to a reading of the Bibl...

radiometric dating the process of assigning "ages" to rocks and fossils based on the breakdown of certain elements into other elements eugenics a "science" founded by some of Darwin's followers, of selectively breeding humans to produce a "master race" index fossil a fossil used by evolutionists to identify the "age" of the rock layer containing it William Paley the 18th-century British theologian who argued that living things show clear evidence of design

BIO112 Spring 2024 Exam 1 Terms radiometric dating general approach used to determine the age of specimens using the rate of decay of radioactive isotopes radiocarbon dating a chemical analysis used to determine the age of organic materials based on their content of the radioisotope carbon-14 potassium-40 dating radiometric dating method often used in the assessment of volcanic intrusions in sedimentary layers. It is based on measurement of the product of the radioactive decay of an isot...

List the current scientific consensus of the age of the a) Universe, b) Earth, and c) Moon, and explain how scientists have calculated these ages - a) Age of the Universe: 13.77 +/- 0.04 billion years old (Measured by calculating how fast our universe is and has been expanding since the Big Bang) b) Age of the Earth: 4.54 +/- 0.05 billion years old (Measured by radiometric dating of meteorites that formed at the same time as Earth.) c) Age of the Moon: 4.425 +/- 0.025 billion years old (M...
