Lets say we have 0.89 mol dm-3 of CH3COOH, a weak acid, with a ka of 1.7X10^-5.We want to find Ph, but to do this we first need to know [H+] because PH = -log10[H+].Because CH3COOH is a weak acid, it only...
Covalent bonding happens when two molecules share a pair of electrons. For example in hydrogen chloride (HCl). Ionic bonding is when two oppositely charged ions are attracted to each other to form a la...
Due to the delocalisation of electrons in the benzene ring conferring more stability on the structure.
Answer: water, followed by hydrogen fluroide, ammonia and lowest is methane.
Explanation: First it helps to write the molecular formulae of these molecules and know their shape:
As group 2 in the periodic table comprises of metals, the reactivity of group 2 elements towards chlorine increases when working our way down the group 2 metals. This is compared to non-metals when the...
