2 → 2 PbO + 4 NO 2 + O 2 PbCO 3 → PbO + CO 2. PbO is produced on a large scale as an intermediate product in refining raw lead ores into metallic lead. The usual lead ore is galena (lead(II) sulfide). At a temperature of around 1,000 °C (1,800 °F) in air, the sulfide converted to the oxide: [4] 2 PbS + 2 O 2 → 2 PbO + 2 SO 2

Four generations of blood glucose meter, c. 1991–2005. Sample sizes vary from 30 to 0.3 μl. Test times vary from 5 seconds to 2 minutes (modern meters typically require less than 15 seconds). A blood glucose meter is an electronic device for measuring the blood glucose level. A relatively small drop of blood is placed on a disposable test ...
Glucose vs. plasma glucose: Glucose levels in plasma (one of the components of blood) are higher than glucose measurements in whole blood; the difference is about 11% when the hematocrit is normal. This is important because home blood glucose meters measure the glucose in whole blood while most lab tests measure the glucose in plasma.
Lead sesquioxide, Pb 2 O 3, which is a lead (II,IV) oxide as well (lead(II) metaplumbate(IV) [Pb 2+][PbO 2− 3]), reddish yellow Pb 12 O 19 , monoclinic, dark-brown or black crystals The so-called black lead oxide , which is a mixture of PbO and fine-powdered Pb metal and used in the production of lead–acid batteries .
FreeStyle Lite, Blood Glucose Monitoring System. This small meter is great for on-the-go blood sugar checks. Not only is it tiny in size, but it also uses a small blood sample, making finger ...

PbO 2 + 2 NaOH + 2 H 2 O → Na 2 [Pb(OH) 6] It also reacts with basic oxides in the melt, yielding orthoplumbates M 4 [PbO 4]. Because of the instability of its Pb 4+ cation, lead dioxide reacts with hot acids, converting to the more stable Pb 2+ state and liberating oxygen: [6] 2 PbO 2 + 2 H 2 SO 4 → 2 PbSO 4 + 2 H 2 O + O 2 2 PbO 2 + 4 HNO ...
