In nuclear physics and chemistry, the Q value for a reaction is the amount of energy absorbed or released during the nuclear reaction. The value relates to the enthalpy of a chemical reaction or the energy of radioactive decay products. It can be determined from the masses of reactants and products.
Answer:
135
Step-by-step explanation:
Two supplement angles add up to equal 180 degrees.
So, (45+x=180)
180-45=x
135=x
One kilometer equals 1000 meters.
2^7 * (3³-1) = 128*26=3328. better check the problem again
