Hello, I'm taking my chemistry exam next week and have to prepare for a few problems. I have to write protolysis equations for tartaric acid. The structural formula shows that there are 4 C, 4 H, and 6 O, but Google gives me the formula C4H6O6. Now I'm wondering how to get from 4 H to 6 H 😬

Loading...This should be Newton/m^2. Even when I convert bar and L to m^3, I just can't get the right unit 🙁 Can someone help me? Preferably step by step with pictures? ❤️ Thanks (the period should be a comma, by the way)
You find it on construction sites…does anyone know what I mean?
Could this be due to technological limitations that cause the IR sensor to measure the temperature of the glass and incorrectly report it as the temperature of the contents? I'm talking about the IR thermometers that you hold outside the object you want to measure. Of course, when it comes to determining the boiling point,…
What is the name of the atom type with the highest EN? (Chemistry)
What is the ratio between 8g copper and 1g oxygen?
At the Cs on which the OH groups hang, a H is also present. This is only not shown so that the structural formula is clearer. Otherwise you would have three-bind Cs in the molecule.
The formula is a skeleton formula. In this, the carbon atoms are simply represented as corners or bar ends and all H atoms bound to carbon atoms are omitted. The number of H atoms results from the four-binding capacity of carbon. Ethan has the skeleton formula — so just one line.
And please write the element symbols big, small really hurts.
