Chemistry

Answer:

Well i know why

Explanation:

Claim: I believe that the corpse flower uses a chemical reaction to emit an odor for reproducing purposes.

Evidence: (credit: national geographic) says, "... a male emits an odor that attract bugs. And after 12 hours the male spray the trapped bugs with pollen  and lets them go. after that the female corpse flower hopefully attracts some of the same bugs that the male attracted and takes the pollen to reproduce." To sum it down the flowers odor is for attracting bugs that  were attracted by the male flower.

Reason: the reason that the evidence supported my claim is  because i answered why the plant gives of an oder and i said for reproducing purposes  and the evidence states the the female flower takes pollen for the bugs given to them by the male flower.

i REALLY hope this helps unlike the other person

Funny thing is i was looking for an answer and all i had to do is copy and paste this one and i ended up answering it my self.

Which element has the following electron configuration: <br> 1s22s22p63s23p64s23d104p65s24d105p5
Natasha2012 [34]
Try adding spaces next time! That's iodine. Check all of the numbers to make sure all of the orbitals are filled, then find the ones which aren't. In this one, only the 5p5 subshell isn't full. 5p5 is the fifth row on the right side, count across the nonmetals and metalloids until the fifth one (a halogen). That's iodine, and that's your answer!

Match each item with the correct statement below.
V125BC [204]

1. LDFs

2. Intermolecular Forces

3. Intramolecular Forces

4. Linear

5. Tetrahedral

Edit: I'm new to this site and idk how to use it properly. I'm not sure about 2 and 3 currently because these forces are between molecules as well so INTERmolecular would be used twice (?)

Bumek [7]

%yield = 54.6%

<h3>Further explanation</h3>

Percent yield is the compare of the amount of product obtained from a reaction with the amount you calculated

(theoretical)

General formula:

Percent yield = (Actual yield / theoretical yield )x 100%

<h3 />

Reaction

2ZnS+3O₂ ⇒ 2ZnO+2SO₂

MW ZnS = 97.474 g/mol

  • mol ZnS

\tt \dfrac{150}{97.474}=1.54

MW ZnO = 81.38 g/mol

  • mol ZnO (from mol ZnS as limiting reactant, O₂ excess)

\tt \dfrac{2}{2}\times 1.54=1.54

  • Actual ZnO produced

\tt 1.54\times 81.38=125.33~g

Theoretical production = 125.388

  • %yield

\tt \dfrac{68.5}{125.33}\times 100\%=\boxed{\bold{54.6\%}}
