Acidul HClO 4 este un acid tare.

a)Scrieti ecuaţia procesului de ionizare în soluţie apoasă
b)Calculaţi concentraţia ionilor hidroniu din soluţie, ştiind că s-au preparat
200 mL soluţie plecând de la 20,1 g acid percloric.
c)Determinaţi pH-ulsoluţiei.

When a spring is compressed, the energy changes from kinetic to potential. which best describes what is causing this change?

Ineed this asap part i: scientific method what is the difference between science and pseudoscience? what is the scientific method?

Phosphorous acid, h3po3(aq) , is a diprotic oxyacid that is an important compound in industry and agriculture. p k a1 p k a2 1.30 6.70 calculate the ph for each of the points in the titration of 50.0 ml of 1.5 m h3po3(aq) 1.5 m h 3 po 3 ( aq ) with 1.5 m koh(aq). 1.5 m koh ( aq ) .
