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.

During an earthquake, the ground surface moves _____. only in a vertical direction not at all in any direction only in a horizon
Elena L [17]

Answer:

In Any Direction

Explanation:

Rayleigh waves, also called ground roll, travel like ocean waves over the surface of the Earth, moving the ground surface up and down. They cause most of the shaking at the ground surface during an earthquake. Love waves are fast and move the ground from side to side.

In your discussion consider a SN2 reaction mechanism concept. Propose a modification of experimental procedure that would improv
Hitman42 [59]

Answer:

Here's what I get  

Explanation:

You may have done a Williamson synthesis of guaifenesin by reacting guaiacol with 3-chloropropane-1,2-diol.

A. Mechanism

Step 1

NaOH converts guaiacol into a phenoxide ion.

Step 2

The phenoxide acts as the nucleophile in an SN2 reaction to displace the Cl from the alkyl halide.

B. Improve the yield

You probably carried out the reaction in ethanol solution — a polar protic solvent.

You might try doing the reaction in a polar aprotic solvent— perhaps DMSO.

A polar aprotic solvent does not hydrogen bond to nucleophiles, so they become stronger.

C. Another method of ether synthesis —dehydration of alcohols

Sulfuric acid catalyzes the conversion of primary alcohols to ethers.

This is also a nucleophilic displacement reaction.

Protonation of the OH converts it into a better leaving group.

Attack by a second molecule of alcohol forms the protonated ether.

A molecule of water then removes the proton.

Calculate the partial pressure of oxygen given the total barometric pressure of 515 mmHg. Round to the nearest hundredth.
Eva8 [605]

The partial pressure of oxygen given the total barometric pressure is : 108.15 mmHg

<u>Given data : </u>

Total barometric pressure = 515 mmHg

Assuming oxygen percentage = 21%

Barometric pressure dry at 37°C

<h3 /><h3>Determine the partial pressure of oxygen </h3>

Applying  the relation below

Partial pressure = oxygen percentage * Barometric pressure

                          = 21% * 515 mmHg

                          = 108.15 mmHg

Hence we can conclude that the partial pressure of oxygen is 108.15 mmHg.
