Answer:
<h2>2.408 × 10²¹ is the correct answer!!</h2>
Change in energy is E=hc/wavelength of emitted photon
We are living in "COENOZOIC ERA".
To solve this we assume
that the gas is an ideal gas. Then, we can use the ideal gas equation which is
expressed as PV = nRT. At a constant temperature and number of moles of the gas
the product of PV is equal to some constant. At another set of condition of
temperature, the constant is still the same. Calculations are as follows:
P1V1 =P2V2
P2 = P1 x V1 / V2
P2 = 2.0 x 1.5 / 3
<span>P2 = 1 atm</span>
Answer:option A
Multiple reactants are used to form one product.
