Should disel and gasoline engines complaint with co2 emissions standards be banned? ? can this statement be answered by science?

Yes.  Emissions at the getgo are not that harmful.  However, when they build up, they can become lethal.  This can be declaired by science in the sense that scientists have done research and done it with monkeys who have relatable body parts with humans.

your parents i think this could be it

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.
