Question

2 INTRODUCTION X Robert Boyle prepared hydrogen gas in 1672. However, he was unable establish that it was an element. The credit for the discovery of hydrogen goed to Henry Cavendish. He prepared hydrogen by the action of hydrochlon acid on iron metal in 1766. He also established that it is an element. H proved that when hydrogen is burnt in air, it forms water. In Greek languae water maker is called hydrogen. Thus, Cavendish named the gas hydrogen​

Answer 1

Explanation:

Hydrogen gas, H2, was first artificially synthesized by Phillip von Hohenheim (known as Paracelsus, Figure 2.1.2 .1) by mixing metals with strong acids. He was unaware that the flammable gas produced by this chemical reaction was a new chemical element. In 1671, Robert Boyle (Figure 2.1.2 .2) rediscovered the reaction between iron lings and dilute acids, which results in the production of hydrogen gas. He noted that these fumes were highly flammable and that the flame gave o a lot of heat but not much light.
