I had taken Chemistr and so should have got all correct 5 out of 8
Thank you very much Grace.
You got 5 out of 8 right!
Great
The score surprised me because this was a high school subject that I didn’t like. lol
I’m sorry I’m late with the answer. Today, I’m reviewing all of my articles from the beginning and responding to missed answers. Thank you.
5/8 good!
You are very much welcome, Robin.
I misclicked a few and horked my score
Thank you very much Alex.
it was a great quiz though
Good quiz, Dragan! I got just 5/8, but made one or two silly mistakes. I never heard of ‘Imperial water’ but I like the name. Just need to be careful not to drink it 😉
Thank you Norma.
. This is an accurate explanation according to the statements of the vikipedija. My question was raised out of my knowledge as I went to a chemistry school.
So: Imperial water (Latin aqua regia) is a mixture of one volume of concentrated nitric acid and three volumes of concentrated hydrochloric acid. It is an easily volatile yellowish liquid. It is extremely caustic. [3] [4] Sometimes it is also called the Royal Guide.
It got its name from being able to react with noble (imperial / royal) metals, primarily gold and platinum that do not react with other substances.
Thanks for the explanation, Dragan. I studied chemistry only until the age of 16.
Good one!!!! , pheww???
Thank you very much Mavic.
My Chemistry is not up to date as it was a long time ago but I got 6 out of 8 .
Bravo Pamela 6 correct answers from chemistry that you once learned.
I did not do well in chemistry but great quiz.
Thank you very much Carol.
I never liked chemistry and it’s still known today
Well everyone has different preferences, chemistry is the subject that I most liked in schooling.
I totally agree with you dear friend …. but I generally did not know how well a student I did not go to school for a long time
It seems that the memory leaves me slowly ?
So if things do not recur, they quickly forget the example is a foreign language.
I had to dig into my memory for these – I missed a couple I guess my memory is faulty!
It’s good to make your mind reminiscent of forgotten things.
