Work = force × distance × cos(angle)
work = (25)(50)(cos (40))
work = 957.56 Joules
= 9.6x10^2 Joules
In the conservation of mass, mass is never created or destroyed in chemical reactions in the same way water is not created or destroyed it is only transferred from one form to another and its mass is always conserved.
