A H₂ molecule is represented as follows:
H-H, Here two hydrogen atom that is H are connected by a single bond that is represented by -.
But here it is given as H-H-, there is presence of an extra bond that is shown after the attachment of two H atoms. So that is wrong in this structure, that is the presence of extra - bond . The wrong thing over here is only that presence of extra bond -.
The correct letter of the answer that states why strong acids are good conductors of electricity is letter B, it is because strong acids have the ability to completely ionize in water, giving the ability of being a good conductor towards electricity. Other choices are incorrect because it applies that it is a poor conductor or it only partially ionize water.
Answer: The force of attraction occurring between two masses.
Ok so, remember that t<span>he average atomic mass is what is seen on the periodic table. It is the average mass of all of the isotopes with their frequency taken into account. What you need to do is add the products of the masses and frequencies Just like this:</span>
<span>0.903*267.8 + 0.097*270.9
When you add it the result is what you are looking for</span>
