It needs to talk about how it affects the body, both negative and positive outcomes. It can also be more than one topic, two preferably.
Thanks in advance!
4.Two scientists are experimenting with pure samples of isotope X, a highly radioactive substance. The first scientist has a sample with a mass of 20 grams. He measures a half-life of 232 seconds. The second scientist has a sample of the same substance with a mass of 80 grams. What is the...
I'm going into A levels and i'll need to choose 3 subjects...what subjects are required to go into equine studies...? i'v searched on the internet, so please dont suggest that :)

A) Molecular
B) Complete ionic
C) Net ionic
D) Atomic
2.

B) Complete...
I'm having a hard time finding a topic to research for my AP chem presentation. Some things my peers have done include, the development of materials used to build basketballs and backboards, how glowsticks work, GMO Salmon, various types of drugs, and artificial food ingredients. Some topics...
I'm literally staring at an empty word document right now.... I'm not sure how to write the "introduction section" or a journal article for a lab we did on gas laws. I didn't even know journal articles had intros! I though it was abstract, data, conclusion (for the most part)! Please help me!!!
Okay, so i was wondering what the periodic trend for ionization energy is and how it applies to the elements in period 3. I thought that the energy increases as you go across the period, but Mg has a higher energy level then Al, according to my assignment. Why is this? :s
It has to affect the human health, and that's about it, thanks!
About the human health thing, it could be a negative or positive outcome.
If you're wondering, this is for a school project in my Chemistry class, and i'm stumped on a interesting topic.
It could be anything, just as long it...
True or false statements.
1. Within a family, elements with higher atomic numbers pull less strongly on electrons in a bond because the atoms have lower effective nuclear charge.
2. Within a family, elements with higher atomic numbers have lower ionization energy because the atoms have lower...
nutrition? I'm doing an extra credit assignment on how chemistry has to do with nutrition. I'm doing it in a Q&A format. What specific questions should I ask? Thanks! :D

labs) next fall? I was told it wasn't the best idea by my counselor and a biology teacher. I wouldn't do it if I didn't have to but I need to take them together for placing into the nursing program priority group 2. I don't mind a lot of work... what should I do? I've run out of options..
Both are branches of physical science and researchers in one often use principles from the other.
Physics is the fundamental science and must be mastered before one is ready to study chemistry.
Chemistry studies only things on Earth, while physics expands to study everything in the universe.
1. When determining the number of significant figures in a measurement,
A) all zeros are significant.
B) all nonzeros are significant.
C) all zeros between two nonzeros are not significant.
D) all nonzeros are not significant.
2. To two significant figures, 0.0255 g must be reported as

Alexander, who weighs 180ibs , decides to climb Mt. Krumpett, which is 5700 m high. For his food supply, he decides to take nutrition bars. The label on the bars states that each 100-g bar contains 10 g of fat, 40 g of protein, and 50 g of carbohydrates.
Alexander wants to know exactly how many...
