Hi,


Anyone is sending their kids to University of Nottingham for this coming September 2021 intake?

Can some one help with this question?


What form (s) of energy do the blades of the ceiling fan possess when the fan is spinning?

Thanks in advance

Re. the above Exam Question.


Things to recognise:-
1) Ammonia is WEAK alkali (Weak alkali has a ph of 10-11.)
2) HCl (on the right hand side of the tube) is STRONG acid (STRONG acid has a ph 0-1)
3) Universal Indicator color: pH 0-1 is RED; pH 10-11 is DARK BLUE (pH 12 is INDIGO)

Answers to your question:-
1) Better pH 10-11 (every difference of 1 in pH is actually 10x in the actual comparison) but the color CAN BE said as dark blue
2) pH CANNOT be 3 as HCl is strong acid.

Hi,


Can someone help to explain this question from O-level 2010 P2A Q3b?

The answers are:
Universal Indicator Paper 1 is Indigo;pH 10
Universal Indicator Paper 2 is Red; pH 1

How do you determine which exact colour and pH to choose? Can the answers be:
Universal Indicator Paper 1 is Blue;pH 12
Universal Indicator Paper 2 is Orange; pH 3

Thanks in advance.

Like to ask mummies who have used peeka before. Do you have their email address for customer service? I have some queries but couldn't find an email address on their website.


Also, what is their handling charges? does it go by per item? or per order regardless of number of items?

Hi hquek and Tamarind,


Just want to share my joy with both of that I finally received my books directly from dangdang!! A good 7 weeks of waiting! I am so happy!!

Tried Peeka as well. Service is extremely good. It’s pricier for the shipping but worth paying if you need the books faster and don’t want to have headache dealing with dangdang.

Still will get from dangdang directly because the price is simply irresistible! Hahaha!

Thanks for assisting me along the way. Appreciate it.

Dear mummies,

I would like to try out Peeka too.
Had registered myself but i dunno how to proceed from there.
I cant seems to locate the \"books\" catergory.
The peeka bring me to this http://www.taobao.com/index_global.php website.
From there, how should i proceed on to order the books from dangdang?

Thanks for all advices.

Hi,

You just need to copy and paste the URL from dangdang over the url of taobao at the Peeka's website once u login to your account. There's a mommy with username \"tamarind\" did a screen shot of the steps in this forum. You may want to search for her id to see how to go abt it.
