Answer:
The hypothetical van't Hoff factor of magnesium nitrate,
is <u>3 .</u>
Explanation:
Lets calculate -

We know that ,

Dissociation should be 100% for the hypothetical vant hoff factor , that is
and
for 
Therefore , putting the given values ,



<u>Hence , the answer is 3.</u>
Answer:
Because it is absorbed by conc . H . SO , to form ammonium sulphate.

<span>Answer: 0.00 meters
Solution:
Step 1: Define displacement
DISPLACEMENT = a vector quantity that describes "linear or angular distance in a given direction between a body or point and a reference position."
Step 2: Understand the question
Assumption 1: Assume that when the ant moves 4.25 meters from its origin to its nest, it is moving in a positive direction (on a graph you would draw a line along the x-axis from its origin to +4.25).
Assumption 2: Assume that when the ant "turns around...back to the source of food", it is moving back in the negative direction (towards the origin).
Step 3: Analyze the question
What is the distance between where the ant originally started and where it ended its journey?
The ant started and ended its journey in the same place.
While it traveled a distance of 8.52 meters (2 * 4.26 = 8.52), it's displacement is actually 0.00 meters (4.26 + (-4.26) = 0.00)
Therefore, the answer is 0.00 meters</span>
