In the following chemical reaction, what product is represented by X? 2NaBr + BaCl2 → 2NaCl + X

A. BaBr2

B. BaBr

C. 2BaBr

D. 2BaBr2

A BaBr2

Explanation:

On the left side of the equation, the superscript 2 is applied to both sodium AND bromine. That means you need 2 bromine on the right. Also on the left side, the 2 AFTER chlorine only applies to the chlorine so there’s only one barium. What you have on the left has to balance with what you have on the right.

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.
