Q:

What are the reactants in a chemical reaction?

Answer

In a chemical reaction, substances (elements or compounds) called reactants are changed into other substances (compounds or elements) called products. Hence, reactants are those which start the chemical reaction.


 


For example:


1. In the burning of natural gas, methane (CH4) and oxygen (O2) are the reactants in the chemical reaction. are the substances formed by a chemical reaction. In the burning of natural gas, carbon dioxide (CO2) and water (H2O) are the products formed by the reaction.


 


2. H2+O2 ----> H2O


Here H2 & O2 are called Reactants and H2O is called Product.

Q:

Order of basicity of amines in gaseous state?

A) 2'> 1'> 3' > NH3 B) 3' > 2' > 1'> NH3
C) 1' > 2' > 3'> NH3 D) 2'> 3'> 1' > NH3
 
Answer & Explanation Answer: B) 3' > 2' > 1'> NH3

Explanation:

The order of basicity in ammonia is different in gaseous phases vs. aqueous phases due to hydrogen bonding.

 

So in gaseous phases it's the well known: 3' > 2' > 1'> NH3. Just so we're on the same page, this is due to the inductive effect of electron donating alkyl groups--they destabilize the lone pair on nitrogen atom, making nitrogen more basic.

 

But in aqueous phase, the order is slightly different: 2'> 1'> 3' > NH3.

Q:

Tell me a suggestion you have made that was implemented in lean manufacturing field?

Answer

It's important here to focus on the word "implemented". "There's nothing wrong with having a thousand great ideas, but if the only place they live is on your notepad what's the point? Better still you need a good ending. If your previous company took your advice and ended up going bankrupt, that's not such a great example either.Be prepared with a story about an idea of yours that was taken from idea to implementation and considered successful.
