Earth's crust
The Moon is primarily made of silicate rock, specifically a type of rock called anorthosite. It also contains minerals like olivine and pyroxene. Additionally, there are traces of metals like iron and titanium in the Moon's composition.
The planet Mercury has the most similar cratered surface compared to the moon.
There is oxygen on the moon, but not as a gas. It is bound up chemically in minerals. Free oxygen, the gas, is not held to the moon as an atmosphere because the moon has not enough gravity to hold a noticeable atmosphere.
Moon rocks are very similar to earth rocks an they are not intrinsically magnetic.
Mercury's surface looks similar to the moon's surface, with craters, plains, and mountains. Both Mercury and the Moon lack an atmosphere, leading to similar erosion and impact patterns on their surfaces.
The moon is a huge ball of rock, chemically similar to the rocks of the Earth's crust and mantle. It does not have a core of nickel and iron, unlike the Earth.
The chemically similar compound to aspirin is ibuprofen.
Arsenic
Opiates
Technetium is chemically similar to manganese and rhenium.
Testosterone
NO
Selenium is chemically similar to sulfur as it belongs to the same group in the periodic table (group 16). Both elements have similar chemical properties and can exhibit analogous oxidation states in chemical reactions.
It is chemically similar enough to dilute it.
The planet Mars has a very thin atmosphere, similar to the moon.
The chemical properties of helium is similar to other noble gases as they all have completely filled orbitals are and chemically inert.
It's similar to our moon.
