Does the composition of a substance always stay the same?
The composition of pure substances, such as elements and compounds, are always the same. The composition of mixtures can vary.
What is the chemical equation for mineral turpentine?
The chemical composition of mineral turpentine can vary, but it is primarily composed of various hydrocarbons such as alpha-pinene, beta-pinene, and carene. The exact chemical equation for mineral turpentine would depend on its specific composition, but these hydrocarbons are the main components.
What is chemical composition of kf reagent?
KF reagent typically refers to Karl Fischer reagent, which is used for moisture determination. It usually consists of an iodine compound, a sulfur dioxide-based titrant, a base (such as pyridine), and a solvent (often methanol or ethanol). The specific chemical composition may vary depending on the manufacturer and type of Karl Fischer reagent.
What is the chemical formula for a fart?
The chemical composition of a fart can vary depending on the individual and diet, but it typically includes gases such as nitrogen, carbon dioxide, hydrogen, methane, and hydrogen sulfide.
What property of a mineral is determined by its chemical composition?
The color of a mineral sample is determined by its chemical composition
Do stars vary greatly in size and color only.?
No. Stars vary in lots of aspects, including:* Diameter * Mass * Color (and the related surface temperature) * Chemical composition * Density (related to mass and diameter) * Brightness
What provides info about the chemical composition of stars?
The composition is determined by spectral analysis.
What is the chemical composition off most stars?
Stars contain hydrogen, helium and a little iron.
Spectrum indicates what in the stars atmosphere?
The chemical composition of the star atmosphere.
What makes a star's spectrum appear to be different from another stars?
The chemical composition of the star.
What is an astrochemist?
An astrochemist is an expert in astrochemistry, the study of the chemical composition of stars and outer space.
Are all stars made up of the same chemical composition?
No. It varies but most are same.
Is fixed composition a caracteritic of a mixture?
A fixed composition is not a characteristic of a mixture. The composition of a mixture can vary, unlike the composition of a compound that forms a chemical reaction.
Why won't the method used to discover the chemical composition of stars work for the moon and planets?
The method used to discover the chemical composition of stars, called spectroscopy, is not as effective for the Moon and planets because they do not emit light like stars do. Instead, they reflect light from the Sun, which makes it more challenging to accurately determine their chemical composition through spectroscopy.
Are all stars identical?
No, not all stars are identical. Stars vary in size, mass, temperature, luminosity, and chemical composition, leading to different classifications such as main-sequence stars, giants, and white dwarfs. Their life cycles also differ based on these characteristics, resulting in a diverse range of stellar phenomena in the universe.
How does a spectrograph provide information about stars chemical composition?
A spectrograph breaks down the light from stars into its component colors or wavelengths. Each chemical element absorbs and emits light at specific wavelengths, creating a unique fingerprint called a spectral line. By analyzing the spectral lines in a star's light, scientists can determine its chemical composition.
Are all the stars the same?
No. Stars vary in mass, color, size, temperature, and composition of trace elements.
