//Discovered:// Oxygen was discovered in 1771 by Carl Wilhelm Scheele and later on uncovered further by Joseph Priestley in 1774. Their discoveries with this gas had paved way for further studies about the importance of oxygen as well as digging <span class="IL_AD" style="background-color: #ffffff; font-family: 'Comic Sans MS',cursive; font-size: 150%;">information <span style="background-color: #ffffff; font-family: 'Comic Sans MS',cursive; font-size: 150%;"> about its physical properties.

Therefore, oxygen therapy is used for people who have trouble breathing due to some medical condition (such asemphysemaor pneumonia).
 * <span style="background-color: #ffffff; font-family: 'Comic Sans MS',cursive; font-size: 150%;">Oxygen gas is poisonous to bacteria that causes gangrene. Therefore, it is used to kill them.
 * <span style="background-color: #ffffff; font-family: 'Comic Sans MS',cursive; font-size: 150%;">Pure oxygen is used to ensure the complete combustion of different chemicals.
 * <span style="background-color: #ffffff; font-family: 'Comic Sans MS',cursive; font-size: 150%;">Oxygen is used to treat water and cut and weld metals.

(P4o10) <span style="background-color: #ffffff; color: #000000; font-family: 'Comic Sans MS',cursive; font-size: 150%;">//... with sodium.// Small pieces of sodium burn in air with often little more than an orange glow. Using larger amounts of sodium or burning it in oxygen gives a strong orange flame. You get a white solid mixture of sodium oxide and sodium peroxide.

While a spark or heat is still needed to start a fire, having concentrated oxygen near various fuels can be very dangerous.
