volume of gas was measured (gasometric analysis). The ideal gas law was then used‚ PV = nRT. Since the volume‚ temperature‚ gas constant (R)‚ and pressure are known‚ the amount of moles of hydrogen can be figured and then converted to mass. The water vapor pressure also was subtracted from the measured pressure in the lab to obtain the correct pressure of hydrogen. The values obtained for the three nails using Gasometric analysis were 0.0815‚ 0.0846‚ and 0.1269 grams. After the stopping point of

Research Question Investigate the effect of temperature on the rate of respiration of various parts of plants (germinating seeds and dormant (non-germinating) seeds)‚ by measuring the oxygen consumption and change in gas volume of respirometers containing either germinating or non-germinating seeds at different temperatures to measure the rate of respiration of these beans at different temperatures. Hypothesis 1.Germinating seeds have a higher rate of respiration as compared to non-germinating

Salvation Rhetorical Analysis Langston Hughes‚ in his personal narrative “Salvation‚” tells of his experience with being pressured by the adult figures in his life to be “saved from sin” and to “come to Jesus” even though he did not feel saved at all. In his piece written in 1925‚ Hughes’s purpose is to show his confusion and loss of faith through the need to please his elders and conform to their beliefs. Throughout the excerpt‚ Hughes conveys a childlike tone in order to highlight his uncertainty

This reaction takes place at 900C (at which temperature the partial pressure of CO2 is 1 atmosphere)‚ but a temperature around 1000C (at which temperature the partial pressure of CO2 is 3.8 atmospheres) is usually used to make the reaction proceed quickly. Excessive temperature is avoided because it produces unreactive‚ "dead-burned" lime. variable-speed electric motor.
