I want to have centerpieces that have a "wow" factor and not a "$$$" factor. So I want to get a bunch of tall cylinder vases and put white/light tan rocks at the bottom, fill it with water, put a betta fish into each vase, and a floating flower or flowers with stems going into the water (not sure). One of these would go onto each table. My wedding theme is actual cherry blossom, but that will play more of a factor in the invites, cake, ect. Any additional ideas? What are your thoughts on these for the tables?

I want to have a cherry blossom themed wedding but I need to find flowers that look similar to cherry blossoms and are readily available in the summer. I also am on a budget so cheaper is better ;)

Thanks for any help!

I will be graduating soon and moving to Atlanta. I have passed the Florida professional exam and the biology subject area exam. Do I have to re-take these tests in Georgia or will they honor my license to teach?

Estimate the value of the equilibrium constant at 505 K for each of the following reactions.

Part A) 2CO (g) + O2 (g) --><-- 2CO2 (g)

Part B) 2H2S (g) --><-- 2H2 (g) + S2 (g)

I'm trying to find K for each of the above. I have tried this over and over and keep getting the wrong answer, please help!!! Thanks!

Calculate the amount of energy in kilojoules needed to change 207 g of water ice at -10 C to steam at 125 C. The following constants may be helpful.

Cm (ice) = 36.57 J/(mol*C)

Cm (water) = 75.40 J/(mol*C)

Cm (steam) = 36.04 J/(mol*C)

Delta H fus = +6.01 kJ/mol

Delta H vap = +40.67 kJ/mol

Thank you for any help!

Predict the sign of the entropy change, Delta S, for each of the following reactions.

a) Pb^2+(aq) + 2Cl-(aq) ---> PbCl2(s)

b) CaCO3(s) ---> CaO(s) + CO2 (g)

c) 2NH3(g) ---> N2(g) + 3H2(g)

d) P4(g) + 5O2(g) ---> P4O10(s)

e) C4H8(g) + 6O2(g) ---> 4CO2(g) + 4H2O(g)

f) I2(s) ---> I2(g)

The answer is either positive or negative for each...thank you soo much, I don't know how to figure this one out and I really appreciate the help!

CaO can be used as a drying agent. One such application occurs when water is added to dry concrete or cement. The reaction that occurs is

CaO(s) + H2O(l) --><--- CaOH2(s)

The product is commonly called slaked lime.

Assuming standard temperature, calculate Delta S total for this reaction using table from the table below.

Substance.....S in J/(K*mol)......Delta H f in kJ/mol

CaO (s).......39.9.................... -635.1

H2O(l).........69.9.................... -285.8

Ca(OH)2(s)..83.4.................... -986.1

Express your answer in joules per kelvin

Thank you so much, i am lost...I know that the answer is NOT -26.4 (i tried it and got it wrong)

I am getting married and have a problem because my in-laws are Asian and they stay true to stereotype. The entire family, distant relatives included, take incredible amounts pictures. It drives me crazy! They even take flash pictures at funerals...I was so shocked when this happened. I just went to my future brother in-laws wedding and the same madness happened. They were setting up cameras in the aisle (two people stood in front of the bride as she walked down the center to take pictures all in her face), getting up (nearly to the alter), getting in the way of the professional photographer, and using bright flashes with loud clicks. It was absurd and really ruined the wedding. I know that the same thing will happen at my wedding but I'm trying to think of ways to keep them from taking pictures. I asked my fiance if we could just include a note in the invitations asking the guests to refrain from bringing cameras but he said that doing this would offend his ENTIRE family. Please help me!!! I really don't want my wedding to be ruined by people being rude.

I need help dealing with my soon to be in-laws. They are asian and I am white, it never was a problem before this but now that we are engaged all sorts of problems are surfacing. I have been dating my fiance for over four years now and we are not going to be getting married for a little over a year from now. The moment we told my family they were really happy for us. But when we told his family they freaked out and told him that he "will not be ALLOWED to get married for another 10 to 14 years!". These people are CRAZY! Reasons they give include the fact that my fiance and I choose to use a ring that I was left from a distant relative. They also had a "meeting" with my parents where they basically told my family that they shouldn't let me get married because they didn't want their son getting married yet, this lasted 3 hours and my mother said that "the things they said were unbelievable". Then they preceded to tell my family that their son would "listen to them unconditionally even when he is 35 years old" because he is Asian not White (yeah right, I know my fiance and they are living in a dream world). I don't understand these people but it is really important for us to have them involved in our life. However if they don't change their tune by the time we send out invitations we are thinking about not inviting them. Does anybody have any advise to help us get through this? or bridge the gap that they have created?
