It was named by French chemist Antoine Lavoisier because when it burns it "creates water ".]]> 2017-10-31 01:26:55 UTC https://padlet.com/440050/k4hqpy6tduwd/wish/201980262 440050 https://padlet.com/440050/k4hqpy6tduwd/wish/201981619 In 1671 Robert Boyle discovered and described the reaction between iron fillings and dilute acids, which result in the production of hydrogen gas. In 1766, Henry Cavendish was the first to recognize hydrogen gas as a discrete substance, by naming the gas from a metal -acid reaction "inflammable air".]]> 2017-10-31 01:35:40 UTC https://padlet.com/440050/k4hqpy6tduwd/wish/201981619 440050 https://padlet.com/440050/k4hqpy6tduwd/wish/201986042 Atomic Number:1

Liquid hydrogen is used in the study of superconductors and, when combined with liquid oxygen, makes excellent rocket fuel. Hydrogen also combines with other elements to form numerous compounds.]]> 2017-10-31 02:17:51 UTC https://padlet.com/440050/k4hqpy6tduwd/wish/201991677 440050 https://padlet.com/440050/k4hqpy6tduwd/wish/201993009 2017-10-31 02:28:29 UTC https://padlet.com/440050/k4hqpy6tduwd/wish/201993009 440050 https://padlet.com/440050/k4hqpy6tduwd/wish/201994231 Hydrogen is important and useful in the real world/ everyday life because we consume hydrogen and were made of hydrogen so without it we wouldn't be alive, as said in the video above. We also use hydrogen for oils, rocket fuel, and there is less than 10 percent of hydrogen in our bodies, and less than .15 percent of the materials that make up the Earth. This is how hydrogen is important in our every day lives. ]]> 2017-10-31 02:38:54 UTC https://padlet.com/440050/k4hqpy6tduwd/wish/201994231
