The statement that correctly explains the molecular structure of water is A. One oxygen (O) and two hydrogen atoms (H2) are joined by a covalent bond.
It cannot be ionic, since ionic bonds tend to be sold at room temperature.
The answer is <span>one liter.

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
Answer:
A heterogeneous mixture is simply any mixture that is not uniform in composition - it's a non-uniform mixture of smaller constituent parts. By contrast, a mixture that is uniform in composition is a homogeneous mixture.
According to Avagadros law 1 mole of a substance contains 6.02 × 10^23 particles.
Thus, 1 mole of C6H14 contains 6.02 × 10^ 23 molecules,
Therefore, 9.25 × 10^24 molecules will have;
(9.25 × 10^24)/ (6.02 ×10^23)
= 15.365 moles.
