Using acidified silver nitrate would reveal the presence of chlorine ions. However, are there other possible ways to detect chlorine in a solution? For example, if I bubble fluorine gas into the solution, would chlorine be displaced and become chlorine gas which I can use litmus paper to detect?

Well, recently I have been wondering about some physics questions that I have came up with. So I will just list them and feel free to answer which ones you can:

1. If an object gets closer and closer to the speed of light it gains (in mass) exponentially, then:
- Can we make an object without mass reach that speed?
- Can we make objects without mass (besides electrons)?
- At the speed of light is there time?
- Can a living organism have a mass of zero so that it may reach the speed of light?

2. In regards to space:

- Does space have any physical attributes so that it is malleable? (A bit broad but do your best!)

Extra comments: I am a strong believer in imagination and intelligence, I am often amazed at how my peers are so involved in Social conduct that they become numb to everything else, it is always important to remember to have an equal balance of interaction in your life. Try not to focus on just one thing!

Get out and live.

one can travel in time - past and future,
one can travel within seconds from far distance to another,
one can see through walls (or opaque object).

i have analyzed: what he meant was - if we can transform (copy) ourselves in different media (which travels at speed of light) then we can achieve the above mentioned.

einstein projected was absolutely correct:
when can copy (or tranform) our image and sound and reproduce, in a audio visual format.

this copy can be send at the speed of light to any part of the world (Television)

when we view this copy in future, we will be viewing past

when we take a video of image and sounds in other room by CCTV, we can see in our room


hence i think einstein was absolutely correct.

I am asking this because someone on another post suggested that such a question be asked that way instead of the usual "Who created the universe".
______

So if some scientist think that life on earth first came from lightening striking mud (something like that), chemical evolution, or out of a sludge that oceans were made out of, why aren't these events repeated? Why was life only first originally created at one period of time, and not in a random period of time through out generations? Or is it? So what is preventing life from originating again? Also if life originated once, then doesn't life eventually run a risk of being extinct at some point?

Lots of questions, I know. Sorry, I can only answer 10 so I need to conserve.

Our teacher challenged us to come up with a function that is definded on R and is unbounded in every neighborhood of x = a for every "a" of R.
Can you help me with this one?

Hello, I'm doing a debate topic for school, the topic is: "Science must come before religion", and the counter team's topic is "Religion must come before science"

My question is that, how would i support this topic (of science must come before religion?)

examples and links would be very much appreciated.

also, how would i use examples from the book "Brave new world" to defend this topic?

thanks

I have a few ceramic cups and bowls that seem to become VERY hot (hotter than the food/drink that it holds) after being zapped in the microwave.

Does this mean it has a high lead content and should I be worried about using them?

simplify each expression:
1) √180
2) 3√18

combine the radicals:
1) √18 + √8 - √32
2) 3√20 - 2√45

multiply or divide then simply:
1) 8√2 x 2√2
2) (3√5)^2
3) (16√21) / (2√7)
4) (5√162) / 9√50

the expression √108 - √3 is equilvalent to:
1) √105
2) 35√3
3) 5√3
4)6

the sum of 9√2 and √32 is:
1) 9√34
2) 13√2
3) 10√34
4) 15
