However, like you, your unborn baby can't efficiently produce DHA and must rely on the placenta during pregnancy, and breast milk or DHA-enriched formula after birth. When you take a DHA supplement during pregnancy and nursing, it significantly enhances the level of DHA available to your baby in and out of the womb.
Confidence votes 8.1K. Oxygen is more electronegative than lithium, a metal. Oxygen has a tendency to gain two electrons so it will bond with two lithium atoms which have a tendency to donate one valence electron for bonding.Li2O.xygen has a tendency to gain two electrons so it will bond with two lithium atoms which have a tendency to donate one valence electron for bonding.

The more reactive of the two metals will win the competition. Consequently if there is a reaction between a metal and a metal oxide then this tells us that the free metal is more reactive than the metal in the metal oxide. Experimental observations. 1  Magnesium reacts with zinc oxide:- Mg + CuO MgO + Cu.eactivity series involving non-metals. Metals react by losing electrons-they are reducing agents. Non-metals react by gaining electrons-they are oxidising agents. In the same way that metals can be ordered in terms of reducing strength, the non-metals can be ordered in terms of their oxidising strength.
