Planets outside solar system are referred to as exoplanets. some scientists have put forward suggestions that there could be living organisms residing in some of the exoplanets. scientists have suggested that some exoplanets are found within the habitable distance from the star they revolve around. at this distance temperature can allow existence of liquid water. Where there is water automatically there is life. so astronomers may infer that life exist in exoplanets by determining whether they are with habitable distance from their star.
Answer:
The mass of 2 moles of Br subscript 2.
Explanation:
Avogadro's number( 6.02x10^23) is the number of molecules/atoms in one mole of an element or compound.
The glass composition from one manufacturer to another varies widely since glass is composed of many consitutents like sand, clay, water, a number of refractories, feldspar and many more. Hence, with the desired application, the composition must also follow. The answer in 1 is a. true. Forensic soil analysis meanwhile does require must extra experience training since it is a rigorous process. The answer 2 is b.false.
Answer: Polarity is the dipole-dipole intermolecular forces between the slightly positively-charged end of one molecule to the negative end of another or the same molecule
An example is H2+ (SO4)2- in Tetraoxosulphate (VI) Acid
Explanation:
In the acid H2SO4, ionization results in the formation of a Positively charged hydrogen ion (2H+) and a negatively charged Sulphate ion (SO4)2-
The slightly positive and negative parts in the ACID generates the DIPOLE (two poles) and THUS explains polarity
Answer:
<h3>Potential energy</h3>
Potential energy is the energy possessed by an object because of its position with respect to a reference.
Explanation:
The energy obtained because of its location or position is called potential energy.
》Example:
Water in a dam stores potential energy because of its height.
