does anyone know where I can buy cheap lava lamps in Singapore? my budget is $20 - $30. small ones would do as well! would really appreciate it if you could give me the name/address of the shop! thanks so much!

the electronic configuration of oxygen is 1s2 2s2 2p4 which would mean that the 2p orbitals have been filled (1 is doubly filled with electrons while the other 2 are singly filled). then how is one electron from the 2s orbital promoted to the 2p orbital to form 4 sp3 hybrid orbitals?

thanks so much!

thanks!

I'm doing a project on making t-shirts for charity and selling them to help the victims of flooding in India. could anyone please help me think of an attention-catching, short and catchy slogan to put on the front of my shirt? thanks, the help is greatly appreciated :D

hey guys could you help me think of how to design a SCIENTIFIC experiment to prove this food myth? there must be some kind of quantitative data collection involved, like how to measure the "chewiness" of meat?

thanks :D

could someone please help me understand the Physics behind it?

I know it's something about the air columns and the vibrations of the air particles so when the sound waves travel further they have longer wavelengths, therefore lower frequencies (because it's the same medium, the speed does not change), so the pitch is lowered?

btw, I am not asking about how to make pan flutes or what length to use, just how it works!

thanks :D

My friends and I am going to an old folks home to do some volunteering and I have no idea as to what the elderly there would like to do :)

Help guys? Really appreciated :D THANKYOU :P

P.S. hmm, I don't think they can do rigorous physical activities. And I hope the activities don't cost too much >.<

I'm doing a history project and i have to write out an election rally/speech.

Erm it would be really helpful if someone could tell me the format of the speech? like how do i start and how do i make it convincing? POh BTW, the election in held in 1954 Singapore :P

thank you :D help greatly appreciated :D

I did an experiment on whether an acidic or alkaline medium would increase the rate of rusting of iron nails and used Coke as my acidic solvent. I noticed that the rate of rusting was highest in Coke and now I need to explain why in my report :/

Could someone please help me come up with a chemical equation for me that shows rusting of iron taking place in carbonic acid? The equations should be balanced :)

Oh yes, and if possible could you guys please help me also to come up with an equation that involves rusting of iron in an alkaline medium?

Thanks a lot :)

Really appreaciate it :P

Can anybody please tell me the pH of bottled green tea and soda water?! Both are alkaline beverages so they pH should be above 7.0

Urgent help needed. Thanks tons people :)

Hey people :)

Could somebody please explain to me how the acid in vinegar can cause iron to corrode? It'd be good if you could elaborate with chemical equations?

Thanks a lot :) Your answers are greatly appreciated! :D

Hey guys!

I am doing a science investigative project on whether an acidic or alkaline medium would cause the rate of oxidation of iron nails to be the fastest. It seems that the solvent Coke causes the most damage to the iron nail in the form of pits (small, black holes.)

Could you tell me what type of acid coke contains and how that acid might promote the process of pitting in iron nails?

Thanks people :) I really appreciate your answers :P

In Shakespeare's Merchant of Venice, Act 3 Scene 4, where Portia and Nerissa disguise themselves as men to save Antonio, what are the literary devices used that generate humour among the audience? This is apart from the fact that in Shakespearean theatres, young males used to the play the roles of woman, so male disguising themselves as males again makes it funny. But what else? :/

Help me please thanks :)

The album is coming out on the 11th of November. Pls. Pls. Hurry. I need to save up!
