The surface tension of which of the following liquid is maximum?

1 answer:

8 0

The cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension. I think the correct answer is option A. H2O will have the highest surface tension due to the hydrogen bonds that are present. Hope this answers the question. Have a nice day.

How do you figure out molality

hodyreva [135]

*The molality of a solution is calculated by taking the moles of solute and dividing by
the kilograms of solvent* Basically if we had 1.00 mole of sucrose (it's about 342 3 grams) and
proceeded to mix it into exactly 1.00 liter water. It would dissolve and make sugar
water. We keep adding water, dissolving and stirring until all the solid was gone. We
then made sure everything was well-mixed.
What would be the molality of this solution? Notice that my one liter of water weighs
1000 grams (density of water = 1.00 g / mL and 1000 mL of water in a liter).

A hardware salesman measures the mass of a box containing

sattari [20]

Step $1$

find the mass of a single washer

Divide the total mass by the number of washers

$\frac{0.4168}{1000} =0.0004168\ Kg$

$0.0004168kg=4.168*10^{-4} kg$

Step $2$

Convert kg to mg

we know that

$1 kg=1*10^{6} mg$

$4.168*10^{-4}*10^{6} =4.168*10^{2}mg=416.8 mg$

therefore

the answer is

$416.8 mg$

When two fluorine atoms bond together in F2, what type of covalent bond do they form?

Angelina_Jolie [31]

The correct statement is " A single bond, because they overlap orbitals to share one pair of electrons." A fluorine atom is unstable with 7 electrons in its valence shell and so needs one more electron to achieve stability. This is according to the octet rule which states that an atom will gain or lose electrons until there are 8 electrons in its valence shell. So each fluorine donates an electron to form a single pair and the $F_2$ achieves a noble gas configuration.
