This is because H2S04 is a diprotic acid. If we look at how the acid dissiociates, we can see that:

H₂SO₄----------> 2H⁺+SO₄^2-

The Kekule model states Benzene consists of 3 pairs of alternating double C=C and single C-C bonds. A typical C=C bond would readily react with bromine to produce a dibromo-alkane and therefore would reac...

Xe is in group 8, the noble gases. Therefore it has 8 electrons in its outer shell. Fluorine atoms have 7 electrons, yet one is an unpaired electron, so this is the electron in fluorine that gets involved...

CH₃-CO-CH₂-CH₃ + 2[H] --> CH₃-CHOH-CH₂-CH₃ NaBH₄ is a reducing agent that effectively produces an H^- ion to act a...

First, let's check we understand the concept of the first ionisation energy. The term is defined as 'the energy required to remove a mole of electrons from a mole of gaseous atoms'. That is, for ea...
