Since the given formula is . According to cross method formula, magnesium has +2 charge so, is multiplied by 2.
Thus, 1 molecule of magnesium phosphate will contain 2 atoms of phosphorus.
Therefore, three molecules of magnesium phosphate contains following number of atoms.
Mg = 9
P = 6
O = 24
Hence, we can conclude that there are 6 atoms of phosphorus in three molecules of magnesium phosphate, .
Non radioactive carbon 13 has 7 protons per atom.
Sugar burns and turns black. A completely new substance was formed, which is the main pointer for it being a chemical reaction. More evidence would be change of color, odor, and the fact that flammability is a chemical property so setting something on fire would be a chemical change.
The ionization energy decreases from top to bottom in groups, and increases from left to right across a period. Thus, helium has the largest first ionization energy
Microscale could be best bet as evaboration and other factors can come in play. otherwise contact angle measurements could have something related calculated via surface tension.
something that is possible, calculating mols via gravimetry.
finding the suitable material could be tricky as if it needs to be instant. silica gel doesn't necessarily work
adsorption vs. absorption
