I'll reward brainliest to whoever can answer this question. : -)

using the following diagram, determine which of the statements below is true:

the activation energy for the forward reaction is −60 j.

the overall energy change for the forward reaction is −20 j.

the activation energy for the reverse reaction is −80 j.

the overall energy change for the reverse reaction is −40 j.

nanotechnology is a powerful tool in biomaterials research as it creates numerous possibilities for the engineering of functional molecules. nano-bio refers to projected ability to incorporate biomimicry into various materials at nanoscale.  

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.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
