Which of the following elements has the highest electronegativity? beryllium iodine calcium nitrogen

Is the water temperature of Lake Michigan affected by the depth of the water?

When methane (CH4) burns, it reacts with oxygen gas to produce carbon dioxide and water. The unbalanced equation for this reaction isCH4 (g) + O2 (g) = CO2 (g) + H2O (g) This type of reaction is referred to as a complete combustion reaction.
