â¢ Analyzing light from the planet tells us about its atmosphere. Density: We determine a planet's makeup primarily by learning its density. For example, Earth's density is about 5.5 times water's density. So, if we learn that a new planet has about the same density as Earth's, we might guess it is similar to Earth.: Scientists determine a planet's ingredients in several ways, depending partly on how close it is to Earth. Planets within our solar system: For planets like Mars that robots have visited, we analyzed rock and atmospheric samples on the spot. We also measure the planet's magnetic properties.
There is an enormous difference between the physical properties of carbon dioxide and silicon dioxide (also known as silicon(IV) oxide or silica). Carbon dioxide is a gas whereas silicon dioxide is a hard high-melting solid.The other dioxides in Group 4 are also solids.here is an enormous difference between the physical properties of carbon dioxide and silicon dioxide (also known as silicon(IV) oxide or silica).

You can say carbon is the main thing here. Compounds of carbon [except oxides, ca â¦ rbonates, bicarbonates] are termed as organic. Water does not contain a carbon atom. So it is inorganic. Carbon dioxide is considered by chemists as inorganic, along with carbon monoxide, carbonates and bicarbonates.Nature has not distinguished compounds into inorganic and organic compounds that clearly.These compounds of carbon are just assumed to be inorganic. Also there is that one thing about carbon being covalently bonded with hydrogen in organic compounds. Due to that criteria carbon dioxide is considered inorganic.But actually there is no clear reason.hese compounds of carbon are just assumed to be inorganic.
