I urgently need an answer please because I have to go whoever answers this first I will like all answers and mark them as most helpful
Hello 🙂 Could someone help me and explain what I need to calculate/do here? Or recommend a YouTube video that will help me understand the whole thing? Thanks!!
Could someone sketch this for me
Hey, ich wollte mal Fragen warum wir eigentlich ehre Laugen/Basen als saure Lösungen im Haushalt nutzen.
I've been trying to solve these two tasks for days, but I just can't get any further. 1) A solution contains 0.10 mol/L silver nitrate and 0.557 mol/L strontium nitrate. Chromate solution is then added dropwise. What is the concentration in µmol/L of the cation that forms the less soluble precipitate at the time when…
Hallo zusammen, Unter welchen Bedingungen könnten zwei Halbzellen als galvanische Zelle genutzt werden (also funktionieren), wenn in beiden Halbzellen Kupfer als Elektrodenmaterial und Kupfersulfatlösung als Elektrolytflüssigkeit verwendet wird?

You are absolutely right that a heptane and a decan together have 38 H atoms.
But at Heptadecan you’re wrong:
Not at all. A continuous chain of 17 carbon atoms.
If you write a heptane and a decane in succession, do you get a continuous chain of carbon atoms?
No, you have something in the middle – CH2 – CH2 – H H – CH2 – CH2 -.
And these two H atoms in the middle are the ones who prepare you headbreaks. In a heptadecane, they do not exist because the chain of carbon atoms passes through. But if you think two separate molecules like a heptane and a decane, they exist.
it’s a good thing
the easiest thing is if you sign this→a C atom always has four connections
you can also easily take this one formula to find out more quickly the H atoms: CnH2*n+2
So, for example, 1 C atom then lasts 2*1+2 4, so you then have 4 H atoms
then as formula: C1H2*1+2
so clear?
I know the general formula, however, what if two alkanes form one. I don’t come to the number of H atoms
To connect the two molecules, you need to remove two hydrogen atoms. Otherwise, your product contains five-binding carbon atoms.
