Answer:
any atom that contains six protons is the element carbon and has the atomic number 6, regardless of how many neutrons or electrons it may have.
Explanation:
D. the potential energy of the reactants is low; the potential energy decreases gradually; then increases slightly.
NaCl is made of Na and Cl
The molar mass of Na = 22.989 g/mol
The molar mass of Cl = 35.453 g/mol
Molar mass of NaCl = 22.989 + 35.453
= 58.44 g/mol
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, .
Well. There is the color change and the formation of bubbles.
