Does this mean that if energy absorbed is more the molecule will dissociate into ions and if it is less molecule will dissociate into free radicals?

Could you explain how?

I hear that methane is known dissociate into free radicals and sometimes into ions (carbocation and hydrogen proton). Is it different amounts energy responsible for the same molecule (methane) to undergoing different kinds of dissociation?

one mole of any gas occupy volume of 22.4dm³ (molar volume) and from equation there are two moles of potassium chloride so volume will be 2×22.4dm³= 44.8dm³. I think they are asking about 2 moles of solid KCl. Is that right?

So is it incorrect statement? Because it is asked in my test. Do you think there is another way of thinking about the question? If this is wrong should I inform it to my teacher so they can cancel the question.

Homework Statement What volume in dm³ of KCl is obtained in the following equation 2KClO3-----> 2KCl + 3O2? Homework Equations None The Attempt at a Solution I suppose there is not enough data and according to equation it is 44.8dm³. But my book says 2 dm³, I don't understand how?

Thank you for the reply! This is making sense to me. But does this electric field is produced across battery terminals because what my teacher told me is "emf is the potential difference between positive and negative terminal of the battery"

What is emf in the coil? As far as I know about emf is that it is potential difference between two terminals of a source but what if it is induced in coil by changing flux linkage. What exactly happen when emf is induced?

My books says Thermite reaction is an exothermic reaction, it release large amount of heat so that temperature increases upto 3500°C On the other hand it is written Melting point of diamond is 3500°C So my question is whether diamond can by melted in such reaction?

Homework Statement [/B] The following reaction was allowed to reach the state of equilibrium 2A+B <====> C The initial amounts of reactant present in one litre of solution were 0.5 mole of A and 0.6 mole of B. At equilibrium the amounts were 0.2 mole of A and 0.45 mole of B and 0.15 mole of...

May you achieve everything you desire. :) BTW Is it right that A very common way of getting information on the function of an organ, part of an organ (such as a region of the brain) or a protein is to look at the outcome (symptoms or phenotype) in cases where it is not functional?

I wonder how were historically functions of the body organs determined? I mean how they dermined working of circulatory system , Nervous system, Excretory system etc?

No this mentions about all types of muscles. Is there any sphincter in glands ?

Yeah but I have to admit this as it is in my book. But there is not much detail of endocrine glands on any site that how they secrete hormones and what is the anatomy of these glands. Thank you for your help

They might refer to lymphatic system. Because any secretion from cells does not happen directly to blood but it first secreted into tissue fluid and then into lymph vessels whose walls are muscular. These lymph vessels return the tissue fluid back to blood vessels along with secretion. Is that...
