Does anyone know of a good virtual flame test lab? We use the HMH Modern Chemistry textbook, and their virtual lab only does one test and seems to focus more on the spectroscopy. I have a link to the Glencoe common assets virtual flame test lab which would work well enough, but it's Flash, so I'd be writing up a lab for something that I won't ever be able to use again.
First of it wastes my time completely. Picture this i wanna do a quick search on something, not to important and not to silly. Here comes fucking me "check my box" to ruin my whole mood Secondly that little piece of the tire slanting on the box below makes it hard as hell to decide wether to click on it and now I've completely lost interest in what i wanted to search
Sorry for grammar
Hi all, the flame test is a great way to check your masks safety. DO NOT TRY TO LIGHG IT ON FIRE.
If the flame is blown out easily, your mask is just not thick enough, add a few layers and try again.
Also Fleece is not a safe mask material, it is actually quite dangerous to use a fleece mask as it attracts particulates and can make you more likely to become sick.
Stay save my friends❤️
I was supposed to identify cations in a solution in a virtual lab. I figured it had Na, Ca and K. The flame test gave a strong yellow due to the presence of Na. So I have a question when doing it in a real lab. Would the solution produce the strong yellow again? Would it give a different color because there are many different cations in the solution?
I found a website saying that any decorations need to go through a flame test before they can get used. I have some posters, plushies, and amiibos/figurines I want to bring (I don’t have a roommate assigned to me if that helps), but will they have to burn my stuff first if I actually want to display them?
Hi, kind of newbie. If I [[test run]] and install the program on [[Flame out]] where will the program go? Stack or heap? Thanks.
I am really struggling here and need you to assist me please as I have run out of what to test.
I am using essential oil + soy wax (464) + wood wicks (from the wooden wick co in USA ).
My problem is: I am getting 70% weak flame and 30% good and strong flame with my small jar candle only and I am not sure where my problem is.
My small jar has a diameter of 47mm and height of 62mm, and I am currently using a wood wick with the measurement of width 0.375" (9.5mm), and I trim my wick to around 1mm - 3mm above the wax which allows it to pick up the flame easily, because I realized if I dont trim it short enough the candle cant be lit at all.
However, I am not getting consistent results, because sometimes the flame is strong, other times it gets so weak that it seems like its suffocating, yet I do exactly the same things when I test.
The test I did today, my wick was about 1mm-2mm above the wax, and while the flame isnt as strong as some of my other tests, it still kept burning, but half way through as I saw the flame getting weaker, I thought I would trim it to see if that helps the candle to burn better, but it didnt. The flame went extremely weak. Should I not have done so?
My other candle is from another test I did a few days ago, it burns very well, and I am not sure why, especially because the length of the wick above the wax is pretty similar.
Can you guys please tell me what is happening here please? I dont even really know the problem.
Hi, we are currently looking at tests to identify different cations in class and I was just wondering how we know that the cation is causing the change in colour. Can't the anion also affect this?
Thanks for helping!
