It all depends on how high or low an objects melting point is. and solid, liquid, and gases are states of matter, you have to play with the temperatures of objects.
But most of the elements on the periodic table are solid at room temperature except gases hydrogen, nitrogen, oxygen, fluorine and chlorine, the “noble” gases helium, neon, argon, xenon, krypton and radon, and the liquids bromine and mercury. The only liquid elements at standard temperature and pressure are bromine (Br) and mercury (Hg). Although, elements cesium (Cs), rubidium (Rb), Francium (Fr) and Gallium (Ga) become liquid at or just above room temperature.
The mostly red pic are the solids, the pic with only two highlighted squared are liquids, the pic with the row of squares are the gases, and the last pic (with dark background) are the synthetic elements
Hope this helps.
Hey I think it is going to be 0986 moles. Cuz we can see that no. of moles of CaCO3 which will decompose is equivalent to the no. of CaO . Now it's just the matter of finding the no. of moles of CaCO3 .

Electrons and protons, but not neutrons.
A mineral is a naturally occurring , solid, crystalline substance with a specific chemical composition. Minerals are usually inorganic and are formed by ionic, covalent or metallic bonding. Ionic bonds are the dominant type of bonds in mineral strictures. 90% of all minerals are ionic compounds. Minerals bonded by covalent bonds are strong, for example carbon bonded together to form diamond. Metallic bonds are a type of covalent bonds where the atoms have a strong tendency to lose electrons and pack together as cations.
