Kate Long

patient #80127 may flower is a 27 year old botanist who recently moved here from brazil she is complaining of severe muscle pain, a fever, headache. and vomiting she also has stiff neck

the objective is to diagnose the patient. The answer is not meningitis.

i think it is a protozoa, because the antibody test came back negative meaning its not a bacteria?

i honestly don't know, but this is for my anatomy and physiology final

these are the disease listed:

amebic Dysentery, Botulism, Chickenpox, Diphtheria , influenza, legionnaires' disease

lyme disease, measles (rubeola), meningitis (bacterial), mononucleosis, mumps, osteomyelitis, pneumonia, poliomyelitis, rabies, rocky mountain spotted fever, rubella (german measles), st louis encephalitis, strep throat, tetanus, tuberculosis, whooping cough

please help

this is about gun control. what law should be created to make the world a somewhat safer place. i'm not sure what to write because there are so many laws and regulations not being properly enforced, so what is the use of another law/regulation/amendment. this is a project and i have no idea what to do.

thanks for all the help!

I think the answer is 1-methyl-2,3,3,4-tetraethylcyclobutane

I also have to choose which carbon is the starting carbon. I belive its the one on top connected to the methyl group.

Thanks for the help.

E)less;G2

You have 1 M sodium phosphate buffer and dry sucrose. How would you make 500ml of the buffer?

*there is one piece of info missing...you have to figure it out in order to find the answer***

This is for my bio pre-lab assignment and I do not understand what I am looking for. Is there someone who can explain or walk me through this question?

I need this information for my global project

please help!

okay so in my reaction the specific heat is

1015.25 J.

The balanced equation is

Ca(s)+2H2O(l)->Ca(OH)2+H2

and the net ionic equation is

Ca+2 + 2H+ +2OH- --> Ca(OH)2+ 2H+

Ca+2 + 2OH- -->Ca(OH)2

What is the number of moles of calcium used in the reaction?

and

What is the number of joules of heat evolved per mole of calcium?

A 2.05 g mixture of potassium chlorate and potassium chloride, upon heating, liberated 425 ml of oxygen. This was collected over water at 21 degrees Celsius and 745 mmHg total pressure. What percentage of pure potassium chlorate was contained in the 2.05 g of mixture. Base your calcualtions on the mole relationships.

This is what I did.

First I did PV=nRT and looked for n

P=(235mmHg/760mmHg)=.98 atm

T=294.15K

V=.425L

R=8.314

(.98atm)(.425L)

when i do the question i get n=.001703x2=.003406 for just O

then .0003406x(1mol KClO3/3molO)x(122.55g/1molKClO3)=.139g

then (.139g/2.05g)x100%=.678%

someone told me it was 68%...am I doing this wrong?

Please Help Me!

a 1.50 g sample of iron containing compound was dissolved in 100.0 ml of solution. A 2.00 ml portion of this solution was placed in a 100 ml volumetric flask and diluted to the mark with deionized water. The iron concentration of this dilute solution was determined to be 1.12x10^-3 M. What percent of this compound is iron?

Can you help me get the answer and explain it?

this is how I got an answer...but it cant be right.

i converted the 1.5g of the sample into moles..which was .02685...

then did M=moles/volume and got (.2685../.002L)=13.429M

then i did this to get the percent (1.12x10^-3 / 13.429 )x100=.0083

this is not right...

Please help me!!

(A) I got this:

KHC8H4O4 M+ NaOH-->KNaC8H4O4 + H2O

KaOH <---> Na++KP-+H2O

(the Wt of KHP is 204.23)**

(B)If 2.8 g of KHP is dissolved in water and titrated with 40 ml of NaOH to the phenolphthalein endpoint...What is the molarity of NaOH??

i got .343 M

is this right???

(C) This is now standardized solution of NaOH is used to find the molecular weight of an acid H2A with has two acid hydrogen. Write the balanced molecular equation for the titration.

i got H2A +2NaOH--> Na2A + 2 H2O

is this right????

(D) If 1.08 g of this acid requires 3.18 ml of NaOH solution for titration to the appropriate endpoint, calculate the molecular weight of the unknown acid H2A.

????

Can you please help me with these questions and show me how to do these questions?

Thank you!

Using standard heats of formation, calculate the standard enthalpy change for the following reaction.

6CO2(g) + 6H2O(l)C6H12O6 + 6O2(g)

okay so this is what i have:

Reactants

6CO2------> -393.5 kJ/mol

6H2O ------> -241.8 kJ/mol

Products

1 C6H12O6------> ?kJ/mol

6O2---------------> 0.0 kJ/mol

is this right? and then after this i have to multipily the coefficants with the delta Hf (the number after the arrwos) and add the products and reactants right?

i have more questions like this so can you please help me....

if you dumped the lumps of sugar from the box and arranged them in one rectangular layer, the area would be 54.cm^2. What would be the thickness of one lump of sugar? If you assume that the lumps of sugar are cubic, how many lumps of sugar were in the box?

so this is what i did

volume of box=(3x4.5x6)=81cm^3

area=54cm^2

thickness=Area/volume=.67cm (thickness)

then .67 cm=diameter of 1 sugar which made me think

(.67)^2*(pi)=area of 1 sugar

.4489*(pi)=1.21cm^2

so the total area of box/area of 1 sugar==(54/1.41)=38 lumps of sugar

is this the right answer?? Did I find the thickness the right way?

Please Help!This is my chem homework

Two drops (1000 drops/cm^3) are placed on a water surface and a continuous, circular film is formed 16 cm in diameter after all the alcohol has evaporated and the oil is distributed evenly on the surface. what would be the thickness of the layer of pure oil?

okay so this is what i did:

i found the area which was 201.06cm^2

the volume by 100 drops/cm^3(2x)---200x.05=10cm^3

then found thickness buy Area/Volume=20.106

so is it 201.06 cm thick???

i just want to know if I did the question the right way.

Thanks!!(This is chem homework)

For the following reaction, 56.5 grams of KHSO4 are allowed to react with 21.4 grams of KOH.

The BALANCED Equation is this.

KHSO4 + KOH = K2SO4 + H2O

What is the maximum amount of potassium sulfate that can be formed?

What is the FORMULA for the limiting reagent?

(i think its the KOH but after that I do everything wrong. please help)

What amount of the excess reagent remains after the reaction is complete?

If a sample of antimony contains 1.85E4 atoms of antimony-121 and 1.39E4 atoms of antimony-123, what is the percentage of antimony-123 atoms in the sample?

Sorry for my last post, the question wasn't all there. Can you please help me with this question. What do you multiply to get the answer. and can you show or tell me how you got your answer. thanks

so the vertex of the parabola is (-1,2) and the focus is (-1,4)

i know that it has to be (x-h)^2=(1/4)(P)(y-k)

and i got up to this (x+1)^2=(1/4)(P)(y-2)

so is p 2? because the focus is 2 above the vertex??

(+√11 , 5) and (-√11 , 5)

and a vertex at (6,5)

i just dont know where to start!

Please help!!
