Answer:

5e6 atoms

Explanation:

Hello,

At first, we must convert from pm to mm to find the diameter of the chlorine atom in mm:

200pm*\frac{1e-12m}{1pm} *\frac{1mm}{1e-3m} =2e-7mm

Now, by dividing the total distance by the distance of one chlorine atom, we can compute how many chlorine atoms are required as they are aligned:

Cl,atoms=\frac{1.0mm}{2e-7mm}=5e6atoms

Best regards.

Diameter = 200pm
200pm -> mm
200pm *^-12 / 1*10^-3 = .0000002
2.0*10-7x mm = 1.0mm
Divide x on both sides

9.54 x 10^-4 mol/L is the solubility of lead(II) iodide in water at 0 C. What is the solubility product constant for lead(II) io
chubhunter [2.5K]

Answer:

Ksp = 3.47x10⁻⁹

Explanation:

When Lead (II) iodide (PbI₂) is added to water, the equilbrium produced is:

PbI₂(s) → Pb²⁺(aq) + 2 I⁻(aq)

And solubility product constant, ksp is:

Ksp = [Pb²⁺] [I⁻]²

A solubility of 9.54x10⁻⁴ M means the maximum concentration of Pb²⁺ is 9.54x10⁻⁴ M and 9.54x10⁻⁴ M×2 of I⁻. Replacing in ksp formula:

Ksp = [9.54x10⁻⁴] [2×9.54x10⁻⁴]²

<em>Ksp = 3.47x10⁻⁹</em>

What is the number of protons and electrons in a neutral atom of<br> Lithium?
nadya68 [22]
If you look at the periodic table you will see the atomic number (the smaller number) which is 3. that identifies how many protons there are. since the lithium is neutral that means there’s a same amount of electrons.

therefore there’s 3 electrons and 3 protons

Which one of the following classes of organic compound does not contain the carbonyl (C=O) group?A) aldehydesB) carboxylic acids
vredina [299]

Answer: alcohols

Explanation:

The carbonyl group refers to C=O. It is contained in aldehyde, Ketones, carboxylic acids , esters, amides and acyl chlorides. They are not found in alcohols. The alchols are generally ROH. They do not contain any carbon-oxygen unsaturated bond in their structure hence the answer.
