<span>Any number that is a multiple of 1.6 is correct, because you can't have a fraction of an electron. Obviously the first one is wrong, because it's charge is smaller than the charge of a single electron, implying that it has a fraction of an electron.
</span>( 1) -3.2x10^-19C
<span>(2 ) -4.8x10^-19C </span>
Answer:
Stars create new elements in their cores by squeezing elements together in a process called nuclear fusion. First, stars fuse hydrogen atoms into helium. Helium atoms then fuse to create beryllium, and so on, until fusion in the star's core has created every element up to iron.
Explanation:
Thank you for posting your question here at brainly. Below are the choices that can be found elsewhere:
12.88 M
<span>0.1278 M </span>
<span>0.2000 M </span>
<span>0.5150 M
</span>
Below is the answer:
<span>5 times diluted (250/50),so 2.575/5=0.515 M
</span>
I hope it helps.
The substance would be:Methanol (ch40)
