Greatest is at W because kendrick is still and it’s at the highest point.. x has greatest gravitational because it’s closest to the ground.. potential energy is at Z because it’s going straight so it’s stil moving
A is correct. Potential energy decreases and turns into kinetic energy.
The balanced chemical equation Lead IV oxide decomposes
to yield lead II oxide and a colorless gas is
Pb3O4 → 3PbO + 1/2O2(g). The key in the balancing of
chemical reaction is to make sure that you got the exact chemical formula of
the substance that is reacting and the yielded product. After getting the
formula, identify first the hardest element/atom to be balanced such as Na, Zn,
Cl, etc. Then proceed to the easier ones such as O, H. Make sure to not the
atoms present in the molecule of the substance.
