You can start by writing out the molecular formula of each molecule.
Aluminum (Al 3+) Phosphate (PO4 3-)
AlPO4
Nickel II (Ni 2+) sulfide (S 2-)
NiS
Aluminum Sulfide
Al2S3
Nickel Phosphate
Ni3(PO4)2
If you’re wondering, we get those charges by looking at the periodic table. The metals usually have a + charge based on their group number. The nonmetals usually - charge egual to 8 - their group number.
You then balance the ions by flipping the charges, dropping the signs, and adding them in as subscripts.
Now we can put it into an equation
AlPO4 + NiS —-> Al2S3 + Ni3(PO4)2
Balance by adding coefficients
2 AlPO4 + 3 NiS —-> Al2S3 + Ni3(PO4)2
Answer:
Explanation:
Entropy is the thermal energy that is unavailable for humans to do useful work.human system normally progress from disorder to order. This entropy interferes with humans day to day activities. Once this energy is consumed it is converted from one form to another and it is the tax paid for those energies. It is the continuous dissipation of energy. For example if 1000J of energy is consumed, and nature take part of it, 900J is available for work.
