He bowling ball has kineti rections when the ball hits them.
2. What happens to the kinetic energy of the bowling ball when the ball hits the
pins?

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
