How many moles of hydrogen are needed to completely react with 2 moles nitrogen?
How many moles of hydrogen are needed to completely react with 2 moles nitrogen? Your question specified 2 moles of nitrogen. I would be quite justified in assuming that the questioner meant 2 moles of dinitrogen gas, i.e. the equivalent of 4 moles of NITROGEN atoms. Thus, if 2 moles of dinitrogen gas are specified, […]
Why are supernovas important?

How do you know if correlation is positive or negative?
How do you know if correlation is positive or negative? We often see patterns or relationships in scatterplots. When the y variable tends to increase as the x variable increases, we say there is a positive correlation between the variables. When the y variable tends to decrease as the x variable increases, we say there […]
Is the sun circumpolar?
Is the sun circumpolar? In the Summer, the Sun is well north of the celestial equator and behaves more like a star near the north celestial pole (more like a circumpolar star) – so it is above the horizon much more than 12 hours. At very northerly latitudes the Sun actually can be circumpolar. The […]
