Answer: I don’t know lol
Explanation: I am so sorry I thought this was easy
Answer:
Explanation:
Rutherford gold experiment gave the explanation to some observations made on atoms.
When he shot the gold foil, most of the -particles passes through the foil undeflected nor absorbed. This faction of the particles propagated the foil as if there was nothing placed on their path.
The surprising behavior of a few of the -particles was that they were deflected from their initial path on hitting the gold foil.
This implies that there is a part of the gold foil which has the same charge as the -particles, and more massive than the particles. Thus, he was able to determine the nucleus of an atom.
Answer: less oxygen available at higher altitudes
Explanation:
The higher in elevation you get, the lower the air pressure, allowing oxygen atoms to spread out farther, therefore making available oxygen less.
Answer: 7.826 x 10^23 molecules
Explanation: 1 mole of NaOH is equal to 40 g, so we can start setting up the equation by saying that 52 g NaOH= 1 mole/40 g. Since one mole= 6.02 x 10^23 representative particles, or molecules, the next step in the equation is to multiply by 6.02 x 10^23/1 mole NaOH. The final equation comes out to be:
52 g NaOH = 1 mole/40g x 6.02 x 10^23/1 mole NaOH = __molecules NaOH
Now all that's left to do is to multiply across the top and divide by the bottom!
