Answer:
The density decreases
Explanation:
The colder the water the closer the particles move together making it denser. The hotter the water the more the particles slow down and move away from each other making the water less dense.
B
The warmer the water, the more space it takes up, and the lower its density.
2H3PO4 +3Ca(OH) 2 = Ca3 (PO4) 2 +6H20
The concentration is 5 g/L.
Concentration = mass/volume = 10 g/2 L = 5 g/L
