Addition of sodium carbonate is a way to soften water by removing calcium ions

<h3>How calcium ions are removed?</h3>

Water can be softened by the addition of lime to precipitate the calcium as carbonate. Sodium carbonate is also added to remove the remaining calcium salts and to make the water soft.

So we can conclude that addition of lime or sodium carbonate is a way to soften water by removing calcium ions.

The most unusual characteristic of Uranus is _____.
fiasKO [112]

Answer:

the axis is tilted at 98 degrees

Explanation:

Uranus is blue, not green; it has an atmosphere of hydrogen and helium, not methane.  While it does have an icy cold temperature, that's not a very unusual characteristic for an outer planet.  However, the tilt of the axis is unusual; no other planet is tilted almost completely on its side!

What is the volume of a 5.30g piece of aluminum? The density for aluminum is 2.70gmL.
Blizzard [7]

The volume of the piece of aluminum is 1.96 mL

Explanation:

Density is the relationship of the mass of a substance and its volume.

In this case, the mass of aluminum is 5.30 g and the density is 2.70 g/mL

The formula to apply is;

D=M/V where D is density in g/mL, M is mass in g and V is volume in mL

2.70=5.30/V

V=5.30/2.70 =1.96 mL
