Zinc reacts with aqueous sulfuric acid to form hydrogen gas. in an experiment, 125 ml of wet h2 is collected over water at 27 degc and a barometric pressure of 753 torr. the vapor pressure of water at 27 degc is 26.74 torr. the partial pressure of hydrogen in this experiment in atmospheres is

What is a possible result of higher air temperature caused by global warming

How much work would it take to move a coulomb charge across a 4 volt potential difference?

The goal of this experiment was to answer the question, "how does diffraction occur? " suppose you formulated this alternate hypothesis: if the gap width is increased while keeping wavelength constant, then the observed diffraction will decrease because the less the ratio between wavelength and gap width is, the smaller the observed diffraction angle will be.to test this hypothesis, you would change the  gap widthdiffraction anglewavelength  and observe the  gap widthdiffraction anglewavelength  in the system.therefore, the independent variable would be the  gap widthdiffraction anglewavelength  and the dependent variable would be the  gap widthdiffraction anglewavelength.
