What happens as the activation energy increases?
EOS
The pressure of the system decreases.
The kinetic energy of colliding molecules changes.
The reactant surface area decreases.
The reaction begins to slow down.

d.) circle motion requires a force to give it a centripetal acceleration.

particle   p is an electron and particle q is a neutron

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
