Fill in the coefficient numbers on the final balanced chemical equations below. If the equations can be simplified (by dividing all coefficients by the same number), please do so. a. HCl + NaOH à NaCl + H20

b. C2H6O + O2 à CO2 + H2O

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
