Three new elements have been discovered. They are X, Y and Z. Element X 6 points has a nuclear charge of 2+, element Y has a nuclear charge of 6+ and
element Z has a nuclear charge of 8+. Explain where these "new" elements
would be placed on the periodic table and why. *
Your answer
In going across a period, the radius of the atom will
1 point

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.

c, liquids evaporate, creating a gas
