Transit theodolites (or just 'Transits') are those in which the telescope can rotate in a complete circle in the vertical plane, whereas the rotation in the same plane is restricted to a semi-circle for non-transit theodolites

Can sodium and oxygen form ionic or non ionic compounds?

Sodium and oxygen can form ionic compounds, such as sodium oxide (Na2O). In this compound, sodium gives up an electron to oxygen, forming an ionic bond due to the difference in electronegativity between the two elements.


What elements combine to form a covalent compound?

If the electronegativity difference between two elements is less than 1.7, then covalent bond is formed between the two atoms.Also, non metals combine with other non metals to form covalent compounds.


The difference between quartzite and quartz is that in quartzite the grains have been?

The difference between quartzite and quartz is that quartzite is a metamorphic rock formed from sandstone under heat and pressure, while quartz is a mineral composed of silicon and oxygen. In quartzite, the grains of sandstone have been recrystallized into a interlocking mosaic of quartz crystals, giving it a more durable and non-porous nature compared to quartz.


What is the difference between unconformity and nonconformity?

An unconformity is a type of geological boundary where layers of rock are missing due to erosion or non-deposition. A nonconformity specifically refers to the contact between sedimentary rocks and igneous or metamorphic rocks. In essence, all nonconformities are unconformities, but not all unconformities are nonconformities.


Is ethyl chloride polar?

Yes, ethyl chloride (C2H5Cl) is polar. The C-Cl bond in ethyl chloride is polar due to the difference in electronegativity between carbon and chlorine, leading to an overall polar molecule.
