Group 2 elements are metals that all form cations in a chemical reaction. This means they lose their valence electrons to become positive (2+) ions. Their reactivity depends on how easily the atoms can lo...
On a periodic table, we can see that the atomic number for lithium is 3. The atomic number represents the number of protons in an atom, so Lithium has 3 protons. The atomic mass is the number of protons a...
A Bronsted-Lowry acid is a proton donor. This means that a hydrogen atom in the molecule can dissociate in aqueous solution to form a H+ ion, and leaving a negatively charged anion.
Halogens are electronegative than the adjacent carbon atoms in haloalkanes.Therefore they have a tendency to attract the pair of electrons in a covalent bond, forming a polar bond.The carbon becomes elect...
Balanced equations: CaCO3 + 2 HCl --> CaCl2 + H2O + CO2 , HCl + NaOH --> NaCl + H2O HCl moles that react overall: (80.0 cm3 x ...
