Questions About: Science
.in Religious Studies in our public schools? (Perhaps such fundamental concepts could be taught in Social Studies classes if not in separate religious studies courses?) After all, how often here in R&S do participants betray their mistaken beliefs that: .all Creationists claim that the earth is only 6000 years old? .all Evangelical Christians deny the processes of Evolution and hate science? .Evangelicals and Fundamentalists believe the same things? .that the word "Christian" has just one overriding definition? .you can't be both religious and an atheist (even though MANY religions have no concept of god/God)? Of course, ignorance of such basic concepts doesn't seem to prevent people from taking loud and adamant positions. As Andy Rooney would say, "WHY IS THAT?"

I need some help calculating solutions and molarity and such. I've been out of school for 18 years and have just gone back to Uni. I'm starting a lab class this week and have to be able to calculate for my solutions for experiment and stuff like that. I wasn't even good at this in high school!! Here are the questions I've had so far (with my some of my working and solutions) can someone please let me know if I'm on the right track.
I've put the question I'm stuck on. Q1) Calculate the molar concentration of 36.5 g HCl in 5 litres of solution mass of HCL 36.5 36.5 5 7.3 M HCL Q2) Calculate the weight of solute contained in 100 mL of 2 M solution of NaOH ? mol NaOH 0.1 L 2 M NaOH ? mol NaOH 2 x 0.1 answer 0.2 grams or 200mg Q3) Calculate the weight of solute needed to prepare a 200mM of NaOH in 100mL ? mol NaOH 0.1 L 0.2 M ? mol NaOH 0.2 x 0.1 = 0.02 grams or 20mg NEED HELP with this one. I'm not sure how the percentage relates to the solution or the rest of it Q4) Calculate the weight of NaCl required to prepare a 0.5% solution of NaCl.
many Molar is that? As much detail as you can would be good (information for dummies would be appreciated! :) Many thanks (from a future science teacher try not to cringe!)

I am in dilemma in which bachelor courses I should choose. I have 2 choices in mind, Bsc(Hons) in Biological Science in HKU SPACE and Bsc(Hons) in Applied Science (Biology and Chemistry). Do anyone of you know which degree cert is more recognized or have a higher employment rate?

Hey, I am in year 10 and just about to make my year 11 subject choices, so its not too late if theres any specific type of science i'll need. i wanted to know how long it takes to become a sonographer, i was looking up sonography because one site made it sound like it was an easy version of a radiologist, is that wrong? coz looking at other peoples question they make it sound like you have to become a radiologist first then a sonographer on top of that?? how long would it take for either of these? and what courses would i take? and also what would the prequisites to get into the courses be? i really dont know much at all about it because most sites are us sites so all help is appreciated even if it may seem obvious to some thanks also what are the differences between these and an x-ray technician?

i want to graduate and get a job in the Human Resources field. However, UC DAVIS does not have Human resources as a major, so i was thinking of majoring in Poli sci: PUBLIC SERVICE and minoring in communication. do u think thats a good combo and will lead to the HR career path? if not, any suggestions? please and thank you :]
