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:
0.808 g x 1000 = 808 mg.
250 ml/1000 = 0.25 L.
808 mg/0.25 L= 3232 mg/L = ppm.
Hope this helps you. Do mark me as brainliest.
Answer:
D) sodium t-butoxide + bromomethane
Explanation:
The alkoxide ion is a strong nucleophile, that unlike alcohols, will react with primary alkyl halides to form ether. This general reaction is known as <em>the Williamson synthesis</em>, and is a SN₂ displacement. The alkyl halide must be primary so the back side attack is not hindered, and the alkoxide ion must be formed with the most hindered group.
The mechanism can be seen in the attachment.
