In Mg 2+-starved plants under low light conditions, the percentage of Mg 2+ bound to chlorophyll has been recorded at 50%. [105] Presumably, this imbalance has detrimental effects on other cellular processes. Mg 2+ toxicity stress is more difficult to develop. When Mg 2+ is plentiful, in general the plants take up the ion and store it (Stelzer ...
MG cars had their roots in a 1920s sales promotion sideline of Morris Garages, a retail sales and service centre in Oxford belonging to William Morris. The business's manager, Cecil Kimber, modified standard production Morris Oxfords and added MG Super Sports to the plate at the nose of the car. A separate M.G. Car Company Limited was ...
Mg(s) + 2 H 2 O(g) → Mg(OH) 2 (aq) + H 2 (g) + 1203.6 kJ/mol However, this reaction is much less dramatic than the reactions of the alkali metals with water, because the magnesium hydroxide builds up on the surface of the magnesium metal and inhibits further reaction.
The kinetics of Mg 2+ transport for the protein were not determined, as 28 Mg 2+ was unavailable. As a substitute, the uptake of 57 Co 2+ was measured and was shown to have a km of 82 μM and a Vmax of 354 pmol min −1 10 8 cells −1. Mg 2+ was a competitive inhibitor with a Ki of 50 μM—the Ki of Mg 2+ inhibition of 60 Co 2+ uptake via ...
The solution has 1 mole or 1 equiv Na +, 1 mole or 2 equiv Ca 2+, and 3 mole or 3 equiv Cl −. An earlier definition, used especially for chemical elements , holds that an equivalent is the amount of a substance that will react with 1 g (0.035 oz) of hydrogen , 8 g (0.28 oz) of oxygen , or 35.5 g (1.25 oz) of chlorine —or that will displace ...

For example, 50 g of zinc will react with oxygen to produce 62.24 g of zinc oxide, implying that the zinc has reacted with 12.24 g of oxygen (from the Law of conservation of mass): the equivalent weight of zinc is the mass which will react with eight grams of oxygen, hence 50 g × 8 g/12.24 g = 32.7 g.
