Answer:
Sodium oxide reacts exothermically with cold water to produce sodium hydroxide solution. A concentrated solution of sodium oxide in water will have pH 14. ... For example, it reacts with dilute hydrochloric acid to produce sodium chloride solution.

The volume of the cube (V) is:
V = l · w · h (l - length, w - width, h - height)
It is known:
l = 10 cm
w = 10 cm
h = 10 cm
Therefore:
V = 10 · 10 · 10 = 1000 cm³
1 cm³ is equivalent to 0.001 liter, therefore 1000 cm³ is:
1 cm³ : 0.001 l = 1000 cm³ : x
x = 0.001 l · 1000 cm³ ÷ 1 cm³ = 1 l
Silicon and Germanium. You can conclude it from its position in the periodic table. Silicon and Germanium are in the same group of the Carbon. That implies that all three have the same number of electrons in the outer orbital, which is responsible for the bonds.
Answer:
D
Explanation:
Rocks turn into sand through heat, wind, and water. D is the most plausible in this situation since it takes time to break them down into sand.
