Hi, http://en.wikipedia.org/wiki/File:Animal_mitochondrion_diagram_en_%28edit%29.svg http://en.wikipedia.org/wiki/File:Chloroplast.svg Greetings, Firelion

Seems perfectly correct to me.

Hi, I´ll help you with the first step: Both formulas express Eph. So you have to replace Eph in both of them and write the remaining parts as one equation. Then the rest should be easy. Greetings, Firelion

oh sorry. We leraned in our exams to calculate very different types of data with the Ka so I thought this task is similar.

Hi, I would try to get the Acid dissociation constant with this little formula: Ka=( [A-]*[H+])/[HA] How many H+ were in the solution? How many mol are 0,7 g H+ ?= c (O) HA = c0 H+ - [H+]. Then you just have to search for the specific the ka in and you have you acid. Greetings Firelion

Hi, Task 1: First note the gonosomes of each individual. Then look at the first male what does he give to his daughter? What happens then his allele is dominant? What happerns if the allele is recessive? Afterwards take a look at the sick individuals: What do you see? Is there a connection to...

Hi, yes, with the help of the Elextronegativity: http://en.wikipedia.org/wiki/Electronegativity For example halogens love electrons very much while e.g Sodium gives them away more easily.

Maybe you can put the Cube under high pressure to prevent the molecules from moving any faster?

Hi, maybe with salt or liquid nitrogen or liquid oxygen. I`m not sure but salt should increase the melting point and liquid gases are as far as I know very, very cold. I hope I could help you.

The Oxygen is neither gained nor lost electrons. It stays by -2. and yes I thibk you`re right.

Thanks for the correction. I´m trying to get used to use English in everday life, so I will make errors , but I´m willing to learn ;)

Hi, pA + pB =14. You can calculate the pH and the change of the pH during different stages of protolyses (?) with the help of the pA and say how a salt reacts with water. I hope I chosed the right vocabulary.

I´m glad to hear I´m not the only one, who likes such topics ;) Maybe you can also writon the action potential of the neurons? they also use electrochemical principels to work.

The Na+ stays as Na+ as long as you don`t dry it. So usually (at least )in school you can ignore it in your equation.

Hi, I´m not sure which one of the reactions happens but your second equation can`t be right in this form, because you left one of the Na+ out and you still need one Cl-, and one O2-. Where got he the H+ from?
