Reactions of the Group 2 elements with air or oxygen

18/8/2020· This page looks at the reactions of the Group 2 elements - beryllium, magnesium, calcium, strontium and barium - with air or oxygen. It explains why it is difficult to observe many tidy patterns. On the whole, the metals burn in oxygen to form a simple metal oxide. Beryllium is reluctant to burn

Acetylene | Encyclopedia

acetylene (əsĕt´əlēn´) or ethyne (ĕth´īn), HC[triple bond]CH, a colorless gas. It melts at -80.8 C and boils at -84.0 C. Offensive odors often noted in commercial acetylene are due to impurities. Acetylene forms explosive mixtures with oxygen or air.
