Answer: I’m guessing ibhs and mr Kadda right?
Explanation:I’m stuck too
Answer:
It should be C,
Explanation:
It's intensive, that is mass independent.
resistance occurs due to electron movement,
for R=0, no electron movement should be there, hence intensive property.
<em>This statement is false.</em> When you say full octet, it means that an element opts to have eight electrons in its valence shell to become stable. However, since a hydrogen atom only has 1 electron when neutral, it is impossible to reach a full octet. That is why Hydrogen is one of the exceptions to this octet rule.
The half-life of Plutonium−239, t1/2 is 2.41 × 10⁴<span> yrs
time taken to reach tolerable level = seven half-lives
= 7 x t1/2
= 7 x </span>2.41 × 10⁴ yrs
= 168700 yrs
= 1.687 x 10⁵ yrs
Hence, the period of time that <span>Plutonium-239 must be stored is </span>1.687 x 10⁵ years.
Answer:
It wouldn't let me post it for some reason. Its all in the picture.
