The poly atomic ion formula for ammonium would be NH4+
Answer:
The methyl group will already be present
Explanation:
You want to make 1-methyl-4-nitrobenzene.
The question is, "Do I start with the methyl group on the ring and then nitrate, or do I start with the nitro group on the ring and then add the methyl group?"
The methyl group is activating and ortho, para directing.
The nitro group is deactivating and meta directing.
You want a para-substituted product, so you choose to nitrate toluene, as in the reaction scheme below.
The first step is to establish a goal and write it down. This adds commitment and you are declaring your intentions.
The second step is write down your daily plan of action. A plan without action is as useless if you had never written the goal at all.
The third step is to share your goal with someone who will hold you accountable. They can share your victories , failures, and provide encouragement.
The final step is to act on that plan. You must take action now that you have all the tools.
Answer:
2 electrons
8 electrons
8 electrons
1 electron (just count in the rings for these ones)
19 protons (it says "P=19" in the middle. The P stands for Protons)
K (it's from Latin medieval Latin "kalium")
39 (add proton and neutron amounts to get the approximate atomic mass--electrons are negligible)
Explanation:
KE = 1/2mass • velocity^2
So, if we take half of 55, we get 27.5
Next, we take 2, and square it, getting 4.
Lastly, take 27.5, and multiply it by 4, getting 110 Joules, hope this helps and have a great day!
