Na₃PO₄(aq)+AlBr₃(aq)→3NaBr(aq)+AlPO₄(s)
This is a double replacement reaction. You can tell that there has to be 3NaBr molecules since there are 3 Na atoms in sodium phosphate and 3 Br atoms in aluminum bromide. We also know that Na has an oxidation number of +1 which means PO₄ needs to have an oxidation number of -3 while Br has an oxidation number of -1 which means Al has an oxidation number of +3. That means that Al³⁺ and PO₄³⁻ can from AlPO₄
I hope this helps. Let me know if anything is unclear.
Answer:
A campfire is an example of entropy. The solid wood burns and becomes ash, smoke and gases, all of which spread energy outwards more easily than the solid fuel. Ice melting, salt or sugar dissolving, making popcorn and boiling water for tea are processes with increasing entropy in your kitchen.

Answer:
74.10g/mol
Explanation:
The mass of one mole of Ca(OH)₂ is the molar mass of the compound.
To solve this problem, we add the atomic masses of the species in the compound;
Atomic mass of Ca = 40.078g/mol
O = 15.9994g/mol
H = 1.0079g/mol
So;
Molar mass = 40.078 + 2(15.9994 +1.0079 ) = 74.10g/mol
