Answer is: gas <span>inside the bubbles that form in the boiling water is most water vapor.
</span>Water vapor bubbles start to form on nucleation sites. The water vapor bubbles start out larger as the temperature gets higher because more liquid is being converted to gas. <span>Vapor-filled bubbles shrink and disappear completely.</span>
Answer:
alright bud lets see hmm.... the answer is a. 90.5kpa
Explanation:
92.3 kPa - 1.82 kPa = 90.5 kPa
keep up your hope also corrected me if a am wrong in anyway! :)
Molecular weight of 1 mole of Argon = 39.948 g
for face-centered cube = x = (√8)r and here r = 191 pm
so, x = √8 x 191 = 540 pm = 540 x 10<span>^-10 cm
</span>density = (39.948g / mol) x (unit cell / 540x10^-10 cm)^3 x (mol / 6.022x10^23 atoms) x (4 atoms / unit cell) = 1.69g/cm^3
so density of solid argon is 1.69g/cm^3
Answer:
The correct answer is B difficult to lose but easy to move.
Explanation:
Metals are chemical substances in which the electrons of the outer orbital or valence orbital are hold very tightly through intramolecular attraction by the nucleus present in the center of the atom of the metal.As a result it is very difficult to remove electron from the valence orbital of metal.
As electrons are hold very tightly by the nucleus of a metal,the electrons are present in very compact manner within metal which helps metal to be an excellent conductor.
