Metals tend to become cations becauase they lose electrons
Answer:
The position of an equilibrium always shifts in such a direction as to relieve a stress applied to the system -Le Chåtelier's principle
A molecule that donates a proton when it encounters a proton acceptor.- Bronsted-Lowry acid
Occurs when a reaction involving an acid and its conjugate base is combined with a second reaction involving a base and its conjugate acid.- Neutralization
It ionizes completely when dissolved in water.- Strong acid
The shift in the position of equilibrium caused by the addition of a participating ion.- Common ion effect
It only partially ionizes when dissolved in water.- Weak electrolyte
It is capable of acting as either an acid or a base depending upon the solute- Amphoteric solvent
The act of self-ionization of a solvent to produce both a conjugate acid and a conjugate base.- Auto-protolysis
A chemical species that bears both positive and negative charges.- Zwitterion
Explanation:
In the answer box we have various chemical terminologies and their definitions. In answering the question, you must carefully read through each definition, then check what option best matches that definition from the options provided.
Each definition applies only to one terminology as you can see in the answer above.
Answer:
<u>Bond energy of</u> (A) C≡C > (B) C=C
<u>and, </u>(C) C=N > (D) C-N
Explanation:
Bond energy refers to the amount of energy required to break a bond or the energy released when a bond is formed. Bond energy of a covalent bond suggests the bond strength of the chemical bond and depends on the <u>bond length and bond order of the chemical bond. </u>
<u>The bond energy of a chemical bond increases with the bond order and decreases with the bond length</u>. As, length of a bond decreases with increase in the bond order.
First pair: (A) C≡C (B) C=C
The bond order of C≡C - 3, the bond order of C=C - 2
Since the bond order: C≡C > C=C
Bond length: C≡C < C=C
<u>Therefore, bond energy of (A) C≡C > (B) C=C</u>
Second pair: (C) C=N (D) C-N
The bond order of C=N - 2, the bond order of C-N - 1
Since the bond order: C=N > C-N
Bond length: C=N < C-N
<u>Therefore, bond energy of (C) C=N > (D) C-N</u>
If the mass of all of the products in a chemical reaction is equal to 100g then the mass of the reactants in that same reaction had to have had a mass of 100g this is due to the law of conservation of matter stating matter cannot be created or destroyed in a chemical reaction.
