Based on our theory of how our own solar system formed, we would expect that other solar systems would be quite common. Based on our theory of how our own solar system formed, we would expect that other solar systems would be quite common.

How does adding salt affect the surface tension of water? if it increases surface tension, will it always increase it?

Which usually has a higher temperature? A city or the areas around the city?

Toluene and pyridine form ideal solutions. Consider a solution of toluene and pyridine prepared at 25°C. Assuming that the mole fractions of toluene and pyridine in the vapor phase are equal, calculate the composition of the solution.

Formula for water what does the lack of a subscript after those O indicate

Why do the chemical properties cycle through each period? Every eighth element starting with hydrogen restarts the transition from metal to inert gas. Elements with atomic numbers which are multiples of eight start a new period.
