Answer:
The temporary hardness of water can be removed by boiling. The bicarbonates get converted to insoluble carbonates and settle down at the bottom.
Calcium bicarbonate -------> Calcium carbonate [insoluble] + Water + Carbon dioxide.
Ca[HCO3]2 -----> Ca CO3 + H2O + CO2
Well, when you leave the water outside, the molecules start to lose some thermal energy and they stop moving, making them more solid and less able to move around. Then, the water turns into ice.

Explanation:
A layer of partially weathered or unweathered rock is present in R soil horizon
Answer is: <span>edge of the length of the box measured is 1280,57 kilometers.
</span>V(raindrop) = 3,48 cm³.
V(cubic box) = 3,48 cm³ · 6,023·10²³.
V(cubic box) = 2,1·10²⁴ cm³.
V(cubic box) = 2,1·10²⁴ cm³ ÷ 10¹⁵.
V(cubic box) = 2,1·10⁹ km³.
r(cubic box) = ∛2,1·10⁹ km³.
r(cubic box) = 1280,57 km.
