Answer/Explanation: The most stable monoatomic ion formed from phosphorus would be the phosphide ion, P3-. Phosphorous has 5 valence electrons and so gaining 3 electrons will make it isoelectronic with the stable noble gas argon, and will produce the P3- ion.
Hope this helps! ^w^
I would say a number about 545.
Kinetic energy of the particles is the measure of energy of the molecules when they are in motion. Kinetic energy is increased when phase change occurs from solid to liquid to gas. Solid has a rigid state which disables the particles to move unlike that in gas and liquid state where liquids can move more because of the spaces in between them.
Answer:
CaC2 + 2H2O > C2H2 + Ca(OH)2
Explanation:
Count the amounts of Ca, C, H, and O, all separately on both sides.
Ca: 1 Ca: 1
C: 2 C:2
H: 2 H: 4
O: 1 O: 2
Now, your goal is to get both sides equal to each other by adding a 2 in front of H2O.
