What else can I help you with?
When a star has no fuel left and its outer layers escape into space what is its remaining core called?
When the layers escape into space, this is classified as a planetary nebula. What usually is left behind is a white dwarf.
What element is 78 percent of your atmosphere?
Nitrogen. 20% is made up of oxygen The remaining ~2% is made up of water vapout, carbon dioxide, noble gases, methane, sulphur dioxide, & ammonia.
What chemicals make up the sun?
The sun is mainly composed of hydrogen (about 74%) and helium (about 24%). Other elements such as oxygen, carbon, neon, and iron make up the remaining 2% of its composition.
What forms 79 percent of the air?
Nitrogen constitutes 79% of the air we breathe. Oxygen accounts for about 21% of the atmosphere, while trace gases like argon, carbon dioxide, and others make up the remaining 1%.
What planet is called the Red planet that is mostly made of carbon dioxide?
Mars is known as the red planet. The planet itself is mostly rock. It is the thin atmosphere that is mostly carbon dioxide.
Is earth surrounded by an envelope of gassed called the hemisphere?
No, the Earth is surrounded by a layer of gases called the atmosphere, not the hemisphere. The atmosphere consists of different gases like nitrogen, oxygen, and carbon dioxide that are held in place by Earth's gravity.
Does carbon dating use nuclear fusion?
No, carbon dating does not use nuclear fusion. Carbon dating is a method used to determine the age of organic materials by measuring the remaining levels of a radioactive isotope called carbon-14. This process involves the decay of carbon-14, not nuclear fusion.
What percentage of carbon is in the soil?
Approximately 58% of the carbon in the soil is in organic form, while the remaining 42% is in inorganic form.
What are the envelope of gases surrounding earth?
The envelope of gases surrounding Earth is called the atmosphere. It is composed mainly of nitrogen and oxygen, along with trace amounts of other gases such as carbon dioxide, water vapor, and argon. The atmosphere plays a crucial role in regulating the planet's temperature and protecting life on Earth from harmful radiation.
How do you address an envelope for someone you carbon copy?
When addressing an envelope for someone you are carbon copying (CC), you should write the primary recipient's name and address in the center of the envelope. In the lower left corner, indicate the CC recipients by writing "CC:" followed by their names and addresses. If there are multiple CC recipients, list each one on a new line. Ensure that the CC recipients' names are clear and easily readable.
How is the age of ancient artifacts determined using carbon dating isotope?
Carbon dating is a method used to determine the age of ancient artifacts by measuring the amount of a radioactive isotope called carbon-14 in the object. This isotope decays at a known rate over time, allowing scientists to calculate the age of the artifact based on the amount of carbon-14 remaining.
Apart from filtering how can you remove carbon from cooking fat?
You can allow the carbon to sink to the bottom of your oil container, decant / pour off most of the oil, and discard the remaining oil with carbon in it.
What is the amount of the original carbon-14 remaining after two half lives?
After two half lives, 25% of the original carbon-14 would remain. This is because half of the remaining carbon-14 decays during each half life, leaving you with 50% after one half life and 25% after two half lives.
How do you calculate age using carbon dating?
When a living thing dies, it stops taking in carbon-14, and the carbon-14 decays into nitrogen-14 at a steady rate. By measuring how much carbon-14 remains, scientists can estimate how old a specimen is.
What is the envelope of gases that surrounds Earth?
The envelope of gases that surrounds Earth is called the atmosphere. It is composed of different layers of gases, primarily nitrogen (about 78%) and oxygen (about 21%), with smaller amounts of other gases such as carbon dioxide, argon, and water vapor. The atmosphere plays a crucial role in protecting life on Earth by trapping heat, blocking harmful radiation, and regulating the climate.
Carbon 12 and carbon 14 are called what of carbon?
Isotopes.
What are carbons that have carbon-carbon double bonds called?
Carbons with carbon-carbon double bonds are called alkenes. They are unsaturated hydrocarbons characterized by the presence of at least one carbon-carbon double bond.
