A student collects hydrogen and oxygen gas by using electrolysis to decompose water. Assuming the pressure and temperature of the gases are held constant, how much Hydrogen gas is formed when 23.0 mL of oxygen gas is formed?
2 H20 -> 2 H2 + O2 (Show your work.)

The concept of empiricism states that all rationally accepted knowledge is determined from experience. francis bacon was one of the first scientists to promote this theory. what was it’s impact on society?

The diagrams show objects’ gravitational pull toward each other. which statement describes the relationship between diagram x and y? gravity attracts only larger objects toward one another. gravity attracts larger objects only if they are close to one another. if the masses of the objects increase, then the force between them also increases. if distance between the objects increases, then the amount of force also increases.

Achemistry student weighs out 0.306 g of citric acid (h3c6h5o7), a triprotic acid, into a 250 ml volumetric flask and dilutes to the mark with distilled water. he plans to titrate the acid with 0.1000 m naoh solution. calculate the volume of naoh solution the student will need to add to reach the final equivalence point. be sure your answer has the correct number of significant digits.
