In the nitrogen cycle, bacteria combine nitrogen gas with hydrogen to form ammonia in a process called nitrogen fixation. It <span> is a process by which </span>nitrogen<span> (N</span>2) in the Earth's atmosphere is converted into ammonia (NH3<span>). Hope this answers the question. Have a nice day.</span>
The safest method for diluting
concentrated sulfuric acid with water is to add acid to water. This way, when
