Answer 1

HELLO THERE!

Here's your answer to the question:


Q1. Where in the body is the most iron located?

Ans: Iron is the most essential part of haemoglobin, so the most part of iron is located in haemoglobin of the Red Blood Corpuscles (RBCs). 

When the haemoglobins are broken in Liver, the iron part is retained and the other part is converted into billirubin and billiverdin, which gives yellow colour to the urine and is excreted.

Note: This is the hidden reason, why human body conducts electricity. Actually the iron present in our body conducts the electric current, due to which we receive fatal shocks which may even lead to death.



Q2. If you fill a glass to the brim with ice water and the ice melts, what will happen?

Ans: The net result will be nothing. If the ice melts, the volume of water will not rise. This is because when ice floats on water, only the one-twelfth part of it lies above the surface of water, the rest being submerged. Moreover, the ice displaces an amount of water according to its own weight. Hence, if the ice melts, there will be no net change in the level of water.


Q3. The symbol Sb stands for stibnum or stibnite. What is the modern name of this element?

Ans: The mordern name of the element is Antimony. This element is present in Group 15 of the 5th Period in the Modern Periodic Table.
