Which equilibrium represents a buffer equilibrium?
OA HI + H20 = H30* +1
OB. HCN + H2O = H30* + CN
OC. NaOH = OH + Na
OD. HCI + H2O = H30* + c
OE. HCIO4 + H2O = H30* + CIO4

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

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 volume increases

some sources quote the lethal dose, for an average 170lbs opiate-naive individual is between 75 and 375 mg
