Why do chemical equations need to be balanced? Group of answer choices
to ensure that the reactants have more atoms than the products
Because otherwise the reaction won't work
because matter, such as atoms, cannot be created or destroyed
The reaction is unstable otherwise

no

explanation:

go away, people want answers, not to hook up

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.

the correct answer to this question is 2

i believe the answer is three water molecules
