Help with naming?

What are the names of the two connections and how can I recognize them
what is the solution?
what is the solution to task 621011
Determine the actual alcohol content in a liquid?
We know that an accurate measurement of alcohol content is possible at a temperature of 20 degrees Celsius. However, the temperature of alcohol in our country is always 26 degrees Celsius. In this case, wouldn't it be possible to measure the actual alcohol content? Or we detected 40 degrees (40%) alcohol in the liquid we…
Chemistry or physics?
Which of these two areas can you relate to?
Can the longest carbon chain be “branched”?
Like here, for example, that would be 2-methylhexane, wouldn't it?
Equivalence points?
ByXerox314
I actually know the subject, but I'm completely confused right now. I have a titration curve where I've plotted the AEP. Now my task is to calculate the molar concentration of the acid. Am I correct to determine the volume of NaOH at which the DP is reached and then calculate the amount of substance…
First of all the indication that zinc(III)oxide is Murks. Zinc occurs almost exclusively and at most as zinc(II).
For (2), the equation ? Fe2O3 + ? C -> ? Fe + ? CO. They are for the quantities you have to use. They would have to be found by some rum-producing, formally, in this case.
Moin,
nothing easier than that:
Fee2O3 + 3 C → 3 CO + 2 Fe
And if we’re here before…
Task 3
CO + H2O → H2 + CO2
Task 4
3 MnO2 + 4 Al → 2 Al2O3 + 3 Mn
But now I really go to bed. Good night…

Is it not C2O4 for the third number of products, since the carbon is four?
Okay, thank you very much, but how do you realize that in the fourth task you have to write the Al2O3 first?
You don’t have to. This is the case with the commutative law. You could also on the right side “3 Mn + 2 Al2O3” write… You could also left “4 Al + 3 MnO2” write. It wouldn’t matter. What matters is that the formulas and the factors before the formulas are correct.
