Carbon-14

Context This Extended Response Task (ERT) will explore the chemistry involved in alloys, where comparisons on composition and melting points will be explored. Furthermore, principles of metallic bonding and electrostatic forces will be investigated to draw conclusion about changes in melting point over various compositions. Along with this, the structure of interstitial and substitutional alloys will be considered, providing insight into the main component of many industrial products. Also, the chemistry

The nucleus maintains its 12 protons and becomes a Mg2+ ion. 2. Given that the half-life of the radioisotope carbon-14 is 5730 years, how useful do you think this isotope would be for dating bones that are over a million years old? Answer: Carbon-14 is incorporated in the tissues of plants and animals through their environment. When they die the incorporation of carbon-14 ends, and what remains in the specimen decays at a constant rate, with a half-life of

What makes carbon so special? Carbon, is a natural occurring elements found in many different compounds such as the food we eat, the clothes we wear and the gasoline that fuels our cars. In addition, carbon plays an important role in the chemistry of life due to its ability to make four bonds with surrounding atoms. Additionally, it can easily bond to other carbon atoms which creates a 4-sided building block for the creation of multi-atomic molecules. The basic structures of every known living organisms

Aim: To investigate how carbon dioxide can affect the rate of photosynthesis. Hypothesis: The rate of photosynthesis in the water plant hydrilla will change as the rate of carbon dioxide changes. Background information: Photosynthesis Photosynthesis is the process of autotrophs turning carbon dioxide and water into carbohydrates and oxygen, using light energy from sunlight. Autotrophs are organisms that are able to produce nutrients and organic compounds using inorganic materials. Examples of

When carbon dioxide (CO2) is absorbed by seawater, chemical reactions occur that reduce seawater pH. This is called “ocean acidification.” Due to the Industrial revolution in the 1800s, the use of fossil-fuels have resulted in billions of tons of Carbon dioxide into Earth's atmosphere (Ocean Acidification). Over time, oceans have absorbed large amounts of the carbon dioxide emitted. On the pH scale, solutions with those with higher numbers are considered basic, while low numbers are considered acidic

environmentally friendly. The students hope their efforts will have a lasting impact by reducing carbon emissions believed responsible for loss of sea ice that's essential to polar bears' existence. "We're excited to be part of something this big," said Alexandra Ruhl, 14, a freshman at South Allegheny High School. "It was overwhelming at times, but we got through it." Ruhl and freshman classmates Jennifer Urban, 14, and Stephanie Mandella, 15, known as "The Energy Angels" team, started in August with a

Vick Hung Draft 1 How does carbon compound in a alcohol affect the energy release from the combustion of the alcohol Introduction In Organic Chemistry unit of our Chemistry class, our teacher taught us about the different types of alcohols, and the different characteristics of them. On my own time with personal interest, I learned more about alcohol, and noticed potential in these substance. The presence of alcohol could be found in many places, from food and ingredient in the kitchen, to bio

Abstract This report extensively analyses the production and breakdown of Ethanols, to assess its properties and their relation to being a fuel. The use of Ethanol as reliable

alcohols. The reaction that is involved in burning alcohols is exothermic because heat is given out. Form this reason the reactant energy is higher than that of the product. The energy is given out when forming the bonds between the new water and carbon dioxide molecules. The amount of energy produced by such exothermic reactions can be calculated by using the formula : Mass of the substance x rise in temp x SHC( specific heat capacity). The specific heat capacity is the number of joules required
