Answer:
Cl
Explanation:
Electronegativity increases as you move up and to the right of the periodic table. For example, Florine is the most electronegative element.
Answer:
37.5 moles of O2 needed
Explanation:
2 moles of C6H6 need 15 moles of O2
5/2 * 15 = 37.5 of O2 needed
This can be solve using the grahams law, which states that the rate of diffusion of the gas is inversely proportional the square root of the molar mass of the gas. meaning the gas with smaller molar mass is the fastest to diffuse
molar mass of the following
F2 = 38 g/mol
CO2 = 44 g/mol
He = 4 g/mol
SO2 = 64 g/mol
NO = 30 g/mol
NH3 = 17 g/mol
so the fastest is He
Answer:
It isn't only for the eating habits but also for building nests, hunting small insects, birds, other creatures including defence. Birds have a narrow small throat so the beak helps ripping off small peices of a big animal l(small bird) and for insects they crush and swallow it, they se their beak for feeding their children by grinding food in their beak and transferring it to the youngsters mouth
