Dinitrogen pentoxide is a white solid. When heated
it
decomposes to produce
nitrogen dioxide and
oxygen.
N2O5→ NO2 O2
How many grams of
oxygen gas will be
produced in this reaction
when 2.34 g of NO2 are
made?

i believe it is-

d.) gravity pulled particles of dust and gas together to form planets.

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.

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.
