A soap molecule has 18 carbon atoms. It contains 70.5% carbon, 11.5% hydrogen, and 10.4% oxygen by mass. It also contains one alkali metal cation. Identify the cation

All copper atoms have atomic number 29: all their nuclei contain 29 protons.

Beryllium.Beryllium oxide is amphoteric

Reddish brown metal is copper (Cu). When copper is heated in the presence of oxygen, it forms copper(II) oxide (CuO) - the black compound. Copper (II) oxide can be reduced...

C. Rings with five or six carbon Atoms

The carbons of CH2=CH and CO have sp2-hybridization. The carbons of CH3 have sp3-hybridization. The distances of C(sp3)-C(sp3) bonds are around of 154 pm. The distances of C(sp3)-C(sp2) bonds are...

Alkali metals are: - Lithium (Li); - Sodium (Na); - Potassium (K); - Rubidium (Rb); - Cesium (Cs); - Francium (Fr). All alkali metals have their outmost electron in the s-orbital. This pre-determines their high chemical...
