I think the compound that has the highest boiling point is CCl4
This is because it has four Carbon-Chloride bonds , while the others have three, two and one and Carbon-hydrogen bonds.
Carbon-Chloride bonds are stronger compared to the Carbon-hydrogen bond, therefore in this case the compound with more C-Cl will have more boiling point.

Answer:  CCl4

Explanation:  Out of CH2Cl2, CCl4, CHCl3 and CH3Cl, CCl4 has highest boiling point.

Boiling point of the liquid is defined as the temperature at which the vapor pressure of the liquid becomes equal to the external pressure of the atmosphere.

It depends on the strength between the molecules and the large surface area.

As larger surface area will lead to the large experience towards the vander wall forces of attraction. Thus CCl4 has larger surface area than the other chlorocarbons . It will experience more vander wall forces of attraction than the other.

What is the molarity of a solution containing 0.5 mol of zinc sulfate (ZnSO4) per liter?
QveST [7]

molarity = G/L/RFM

RFM = 120+32+48= 200

0.5/200 = 0.0025

4. Consider the following statement made in Chapter 4 of the text: "... consider that if the
AveGali [126]

The claim: "If the nucleus were the size of a grape, the electrons would be one mile away on average" is reasonably accurate because the ratios between the nucleus's sizes and the distances (between electrons and nucleus) for the two given examples are in the same order of magnitude.      

To know if the claim is accurate we need to calculate the ratio of the size of the nucleus (the same as a grape) and the distance between the electrons and the nucleus for example 1 (r₁):  

r_{1} = \frac{s_{1}}{d_{1}}    (1)

and to compare it with the ratio of the size and the distance given in example 2 (r₂):

r_{2} = \frac{s_{2}}{d_{2}}    (2)

<em>Where:</em>

s₁: is the size of the nucleus (like the size of a grape)

d₁: is the distance between electrons and nucleus of example 1 = 1 mile

s₂: is the average diameter of the nucleus  = 10⁻¹³ cm

d₂: is the average distance between electrons and nucleus of example 2 = 10⁻⁸ cm

Assuming that the diameter of a grape is 3 cm (in a spherical way), the ratio of the <u>first example</u> is (eq 1):

r_{1} = \frac{3 cm}{1 mi*\frac{160934 cm}{1 mi}} = 1.86 \cdot 10^{-5}

Now, the ratio of the <u>second example</u> is (eq 2):

r_{2} = \frac{10^{-13} cm}{10^{-8} cm} = 1.00 \cdot 10^{-5}              

Since r₁ and r₂ are in the same order of magnitude (10⁻⁵), we can conclude that the given claim is reasonably accurate.

2) Which element is used as fuel in nuclear reactors? How many years before we run out of it?
Firlakuza [10]

Answer:Uranium

80 years

To make that nuclear reaction that makes that heat, those uranium pellets are the fuel. And just like any fuel, it gets used up eventually. Your 12-foot-long fuel rod full of those uranium pellet, lasts about six years in a reactor, until the fission process uses that uranium fuel up.

Transuranic wastes, sometimes called TRU, account for most of the radioactive hazard remaining in high-level waste after 1,000 years. Radioactive isotopes eventually decay, or disintegrate, to harmless materials. Some isotopes decay in hours or even minutes, but others decay very slowly.

Hope this helps
