Which of the following statements is/are true regarding hydrogen bonds in water?

kap26 [50]

Answer

B,C,D,E

Explanation:

Hydrogen bonds in water forms a tetrahedral ( four sided structure) and not a six sided structure.

The hydrogen bonds are needed to be broken first when heat is applied to change from one state to another.It makes room for more heat to be applied than the required amount which signifies a higher latent heat of melting or vaporization and also a higher heat capacity .

What role does the salt bridge play in a voltaic cell? It allows electrons to flow from the anode to the cathode.It allows migra

Mnenie [13.5K]

The answer is it contains the electrodes. Without the salt scaffold, the arrangement in the anode compartment would turn out to be decidedly charged and the arrangement in the cathode compartment would turn out to be contrarily charged, on account of the charge lopsidedness, the terminal response would rapidly stop.
It keeps up the stream of electrons from the oxidation half-cell to a decrease half cell, this finishes the circuit.

how many liters of a 60% antifreeze solution must be added to 8L of a 10% antifreeze solution to produce a 20% antifreeze soluti

Tasya [4]

Answer: 2Liters

Explanation:

The expression used will be :

$M_1V_1+M_2V_2=M_3V_3$

where,

$M_1$ = concentration of first antifreeze= 60%

$M_2$ = concentration of second antifreeze= 10%

$V_1$ = volume of first antifreeze = x L

$V_2$ = volume of second antifreeze = 8 L

$M_3$ = concentration of final antifreeze solution= 20%

$V_3$ = volume of final antifreeze = (x+8) L

Now put all the given values in the above law, we get the volume of antifreeze added

$60\times x+10\times 8=20\times (x+8)$

$x=2L$

Therefore, the volume of 60% antifreeze solution that must be added is 2L

Which quantity is equivalent to the product of the absolute index of refraction of water and the speed of light in water?

givi [52]

The quantity which is equivalent to the product of the absolute index of refraction of water and the speed of light in water system is the speed of light in vacuum.

<h3>What is the speed of light?</h3>

Speed of light is the rate of speed though the light travels. To find the speed of light in any medium, the following formula is used.

$v=\dfrac{c}{n}$

Here, (n) is the index of reaction and (c) is the speed of light in the vacuum. The speed of light in the vacuum is almost equal to the 3.0×10⁸ m/s.

Now the quantity which is equivalent to the product of the absolute index of refraction of water and the speed of light in water has to be find out.

The above formula can be written as,

$v=\dfrac{c}{n}\\vn=c\\c=vn$

Here, the product of index of refraction and speed of light is equal to the speed of light in vacuum. This will be true for water as well.

Thus, the quantity which is equivalent to the product of the absolute index of refraction of water and the speed of light in water system is the speed of light in vacuum.
