Answer:
2AlPO4(aq) + 3Mg(s) -------> Mg3(PO4)2(aq) + 2Al(s)
Explanation:
The principle of writing balanced chemical reaction equations states that; the number of atoms of each element on the right hand side of the reaction equation must be equal to the number of atoms of the same element on the left hand side of the reaction equation.
The reaction is between aqueous aluminum phosphate reacts and solid magnesium to produce solid aluminum and aqueous magnesium phosphate. The equation is represented as follows;
2AlPO4(aq) + 3Mg(s) -------> Mg3(PO4)2(aq) + 2Al(s)
Ka expression for any substance:
Ka = [H+] [A-] / [HA]
In this case,
Ka = [H+][C₃H₅O₃-]/[C₃H₆O₃]
1.4 x 10⁻⁴ = [H+] [C₃H₅O₃-] / [C₃H₆O₃]
pKa = -log(Ka)
pH = -log([H+])
The difference between pKa and pH is that pH is the negative logarithm of only the concentration of hydrogen ions, while pKa is the negative logarithm of the ratio of the product of the concentrations of hydrogen ions and concentration of base to the concentration of acid.
Answer:
Ionization smoke detectors use americium as a source of alpha particles. Alpha particles from the americium source ionize air molecules. This makes some particles positively charged and some negatively charged. ... Because of this shielding, the smoke detector poses no radiation health risk when they are properly handled.

Answer:
4s, 3d, 4p
Explanation:
(3d,4s,4p) and (4p, 3d, 4s) both are decreasing energy, while (4s,4p,3d) is incorrect order it should be (4s,3d,4p).
The answer is c because fusion is way more dangerous and complicated and extremely hard to do, so they rely on fission, the splitting of atoms
