<u>Answer:</u> The experimental van't Hoff factor is 1.21
<u>Explanation:</u>
The expression for the depression in freezing point is given as:
![\Delta T_f=iK_f\times m](https://tex.z-dn.net/?f=%5CDelta%20T_f%3DiK_f%5Ctimes%20m)
where,
i = van't Hoff factor = ?
= depression in freezing point = 0.225°C
= Cryoscopic constant = 1.86°C/m
m = molality of the solution = 0.100 m
Putting values in above equation, we get:
![0.225^oC=i\times 1.86^oC/m\times 0.100m\\\\i=\frac{0.225}{1.86\times 0.100}=1.21](https://tex.z-dn.net/?f=0.225%5EoC%3Di%5Ctimes%201.86%5EoC%2Fm%5Ctimes%200.100m%5C%5C%5C%5Ci%3D%5Cfrac%7B0.225%7D%7B1.86%5Ctimes%200.100%7D%3D1.21)
Hence, the experimental van't Hoff factor is 1.21
Answer:
It kind of is logical so my answer is yes
It's a surface current because it's driven by the winds near the equator.
Explanation:
The Gulf stream<span> System is </span>one of<span> the world's most intensely studied current systems. The </span>Gulf stream<span> begins upstream of </span>the promontory<span>, </span>wherever<span> the </span>Sunshine State<span> Current ceases to follow the </span>seabed<span>. The position of the Stream </span>because it<span> leaves the coast changes throughout the year. </span>within the<span> fall, it shifts north, </span>whereas within the<span> winter and early spring it shifts south.</span>
Answer:
it gets rust and could not run properly
<u>Answer:</u> Group 1 ions are known as cations and Group 17 ions are known as anions.
<u>Explanation:</u>
Ions are formed when an atom looses or gains electrons.
If an atom gains electrons, it leads to the formation of negative ions known as anions. <u>For Example:</u> Fluorine is a Group 17 element which gains 1 electron to form
ions.
If an atom looses electrons, it leads to the formation of positive ions known as cations. <u>For Example:</u> Sodium is a Group 1 element which looses 1 electron to form
ions.
Hence, group 1 ions are known as cations and Group 17 ions are known as anions.
