Explanation:

want more facts? Here u go!

The four planets closest to the Sun—Mercury, Venus, Earth, and Mars—are the inner planets or terrestrial planets (Figure below). They are similar to Earth. All are solid, dense, and rocky. None of the inner planets has rings. Compared to the outer planets, the inner planets are small. They have shorter orbits around the Sun and they spin more slowly. Venus spins backward and spins the slowest of all the planets.

All of the inner planets were geologically active at one time. They are all made of cooled igneous rock with inner iron cores. Earth has one big, round moon, while Mars has two very small, irregular moons. Mercury and Venus do not have moons.

Dimas [21]

For lead fluoride Ksp = s³

For Aluminum hydroxide Ksp = s⁴

Explanation:

The expression for the solubility product can be written as the product of the concentration of the ions present in the solution.

PbF₂ → Pb²⁺ + 2 F⁻

Then the Ksp can be written as,

Ksp = [ Pb²⁺] [F⁻]²

If the concentration can be considered as s, then the Ksp can be written as,

Ksp = s× s² = s³

For Aluminum hydroxide on dissociation it gives 4 ions as,

Al(OH)₃ → Al³⁺ + 3 OH⁻

Ksp = [Al³⁺] [OH⁻]³

= s × s³ = s⁴

Thus,For lead fluoride Ksp = s³

For Aluminum hydroxide Ksp = s⁴

In which type of chemical bonding are electrons shared between adjacent atoms?

Vikki [24]

In covalent bonding electrons are shared betweed adjacent atoms.

This kind of bonding means that none of the atoms are detached from its electrons.

A molecule of compound is formed when two or more atoms are bonded through covalent bonds. The electrons shared are considered part of the valence electrons (outer energy level) of both atoms forming the covalent bonding.

How do charged molecules pass through the membrane.

avanturin [10]

Answer:

Through transport proteins

Explanation:

There's two transport proteins, channel/pore protein and carrier protein. Charged/polar molecules or ions need specific transport proteins to pass through across the plasma membrane. Transport proteins allows ions/polar molecules to bind to the specific site and allow them to pass through and enter the cell.

(btw, is this a chemistry question? isn't this a biology ques?)

Consider a piece of gold jewelry that weighs 9.85 g and has a volume of 0.675 cm3 . The jewelry contains only gold and silver, w

AlekseyPX

Answer:

61.5096 %

Explanation:

Let the amount of gold in the jewelry = x g

Let the amount of silver in the jewelry = y g

Total mass of jewelry = 9.85 g

So,

x + y = 9.85 g .................................1

Density = Mass / Volume

Given that:

Density of gold = 19.3 g/cm³

Thus, volume is:

Volume = Mass / Density = x / 19..3 cm³

Given that:

Density of silver = 10.5 g/cm³

Thus, volume is:

Volume = Mass / Density = y / 10.5 cm³

The total volume of the jewelry = 0.675 cm³

So,

$\frac {x}{19.3}+\frac {y}{10.5}=0.675$

Or,

10.5 x + 19.3 y = 136.78875 ................2

Solving 1 and 2, we get that:

x = 6.0587 g

y = 3.7913 g

So, mass % of gold:

Mass % = (6.0587 / 9.85)×100 = 61.5096 %
