The following questions are about ceramic silicon nitride size: 1) determine the type of chemical bonding between si and n, given the electronegativity of si and n are 1.8 and 3.0, respectively. 2) if si forms tetrahedron with n, what is the coordination number of si? what is the hybridization type of si, sp, sp or sp ? 3) how can the sina tetrahedra be linked to satisfy the 3: 4 ratio of si to n

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

it means there are 3 atoms of oxygen

pv=nrt

explanation:

window cleaner is ammonia dissolved in water. this is an example of a
