Hello, i am going to buy a laser and a telescope powerful enough to see the laser spot on the moon. The lunar phase i choose for the experiment is New Moon, for obvious reasons. When i move the laser, i should see the light spot move on the moon surface after about 2.5 seconds, due to the light...

hello, i have a doubt i bought some small neodimium magnets 8x3mm and now i would like to try some experiments with them i have a doubt: if i rotate one of these magnet around one of its parallel axis, very fast , near 1000000 rpm, what happens to the magnetic field produced by the magnet? if...

hello, i am a near light runner at 3000000 km from us there is a mirror to start the run , my friend turns on a very powerful lamp and i start running toward the mirror me and my friend will see both the light coming back after 20 seconds?

thank you, i think so too

this is the question :) perhaps to know the concentration in percent i need to know the mass of 1L of the 2M solution... i can guess...380g is 6% of (380/0.06)g = 6333g so i have to add 6333 - 380 = 5953g water, that is about 6L water. So total volume is 6Lwater+380g tin chloride..i don't know...

189,6 g/mol so i have about 380g SnCl2 in 1L of the 2M solution...

it is 6% in weight? how can i get a 6% tin chloride solution starting from a 2M solution? thanks

Thank you very much for the answer yes, you are right, i did a mistake, i wrote 50cl, but it was 50ml. About my project: 2M solution is very concentrated, this is needed only to melt tin. To sensitize the plastic i need lower concentrations: - an author suggests to make a 0.003M solution and...

i need this solution to try to do silvering of a plastic surface for my hobby project the tin solution in this case will be used as 'sensitizer', i.e. it willbe used to prepare the surface to be silvered... i have only a scholastic background, not a professional/expert background thank you for...

hello, i would like to make a tin chloride solution without having to buy the tin chloride crystal powder. i know that tin and hcl are enough, but i would like to know how they can mixed ,and in which proportion, to get a specific concentration. i found an example where are used: 12gr pure tin...

thank you yes, i found that the tin chloride solution is used to enhance the adesion, it is a 'sensitizer' and to have better results, the object surface must be covered with a wetting agent (a surfactant) before applying the tin chloride solution. about this solution, i found some methods to...

hi to all, i have some questions about glass silvering; i found this procedure: 1) make a solution (A) with 1.4 gr silver nitrate + 17gr water then, add to the solution 1.2gr of ammonia 26% solution 2) make a solution (B) with 9.2 gr potassium bitartrate + 4gr sodium carbonate + 17gr water 3)...

hello, i am lodovico, lovicodo is the nick name i am from italy i joined this forum because i love diy, and for my projects sometime it is needed to use chemicals i hope to learn something to use them in the best and safe way
