Which has more mass a leaf or a quarter?
the leaf is made of many layers; cuticle upper epidermus palicade layer (chlorophil with green pigment preforming photosynthesis is here) spngey layer (this is the biggest layer, with many gaps and holes to absorb water vabors and carbon dioxide) lower epidermus and stomata
What is the radioactive form of carbon?
There are several radioactive forms of carbon. The most familiar, used in carbon dating, is carbon-14. All of the others have very short half-lives.Isotopes of carbon range from carbon-8 to carbon-22. Carbon-12 and carbon-13 are stable and non-radioactive. Carbon-14 has a half-life of 5730 years. The longest lived beyond that is carbon-11 at 20.3 minutes.
What does the element carbon-40 decay to?
There is no element carbon-40. The highest known isotope of carbon is carbon-23. Please restate the question.
Iron melt at about 1700 degree Celsius. why all carbon in it does not burn out at that temperature?
Carbon can essentially dissolve in molten iron. Carbon only leaves iron if it is exposed to oxygen to make carbon dioxide. This happens in the process of converting iron to steel where the carbon content is controlled to desirable levels.If we heat the carbon in absence of oxygen, it will not be oxidized to carbon bi oxide. When you heat the Iron it melts. Through carbon is ready to get burn, it can not burn in the absence of oxygen and so it remains as carbon only. All around the carbon atoms, there are Iron atoms and as such it can not be converted to carbon bi oxide. It means if heated carbon is surrounded by iron atoms, it will not be oxidized and after cooling, it will remain as carbon only.
Is carbon conductor or insulator?
is carbon a conductor or insulator
What is the mass number of carbon14?
Carbon is a non metallic element. Mass number of it is 12.
What Limitations are there of using carbon14 to date rocks?
The main limitations of using Carbon14 dating to find the age of something that is carbon base are firstly the possibility that carbon may be absorbed by some things making it more difficult to get an absolutely accurate age and secondly, with Carbon14 only having a half life of 5,568 years the maximum theoretical limit for detection is 100,000 years.
Why are atomic masses written as averages?
elements exist in more than one form eg carbon 12 and carbon14
Why is carbon14 dating not accurate for estimating the age of materials more than 50.000 years old?
Too little carbon-14 remains after 50,000 years
What two things must scientist measure to find the absolute age of a rock?
scientists use carbon14 and potassium argon to find absolute age of rock
Is carbon ancient?
Yes .
A researcher who uses carbon dating on ancient items?
a researcher who uses carbon dating on ancient items? is an archaeologist.
A researcher who uses carbon dating on anciet items?
The half life of C14 is about 5700 years, so items that are a few multiples of this time are suitable for carbon14 dating. Most archaeological items are suitable, and some young fossils.
When a process or activity offsets its carbon emissions enough that its carbon footprint effectively reaches zero it's said to be?
Carbon Neutral
What is the method of ancient remains?
carbon dating
How does volcanic activity affect carbon dioxide?
it seperates the diatomic molecule and makes it a monotomic molecule, or carbon monoxide
What would happen to the temperature of the atmosphere if carbon dioxide increased due to human activity?
It will rise. The temperature of the atmosphere is rising already because carbon dioxide is increasing due to human activity.
