A lot of cooking involves chemistry and is essentially a series of chemical reactions. Knowing about this kitchen chemistry can help you to understand much more about what’s happening – and why your recipes sometimes go wrong.Bananas turning brown is kitchen science.Why curry is hot uses chemical formulas.What happenes when meat cooks involves chemical formulas.Why popcorn pops inovopves chemical formulas.And,why honey is good for sore throats involves chemical formulas.
The 4th energy level (row), 's' orbital block, 2nd group (column). The valence electrons are found in the highest energy level of the electron configuration in the 's' and 'p' orbitals. In the case of calcium this is 4s2 . This gives calcium an 's' orbital with a pair of electrons in its valence shell
ΔΗ= -115.6 kJ/mol
H2 has a Mr of 2, so as mol=mass/mr we can work out that there are 4 moles of H reacting
Therefore we multiply -115.6 by 4 = -462.4
A: Na3PO4 + MnCl2 > Mn3(PO4)2 + NaCl
