Amixture of nh3(g) and n2h4(g) is placed in a sealed container at 320 k . the total pressure is 0.50 atm . the container is heated to 1200 k at which time both substances decompose completely according to the equations 2nh3(g)→n2(g)+3h2(g) ; n2h4(g)→n2(g)+2h2(g) . after decomposition is complete the total pressure at 1200 k is found to be 4.5 atm. part a find the percent (by volume) of n2h4(g) in the original mixture. (assume two significant figures for the temperature.)

Choose all that apply. when creating a graph, you should: determine the x- and y- variables label the scale on the x- and y- axes plot the data points draw a line of best fit to represent the data trend

Since the gas in your graduated cylinder is a mixture of butane and water vapor, you must determine the partial pressure of the butane, pbutane, alone. to do this, consult a reference and record the partial pressure of the water vapor, pwater, at the temperature you recorded. use the following formula to compute the partial pressure of the butane. pbutane = atmosphere - pwater use the following combined gas law formula and compute the volume that the butane sample will occupy at stp. (hint: convert both temperatures to kelvin.) pbutane x voriginal = pstandard x vfinal troom tstandard use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. grams of butane you used “x” grams of butane ml of butane corrected to stp = 22,400 ml compute the theoretical molar mass of butane based on its formula and the atomic masses on the periodic table. compare your experimental results from #3 to the theoretical value of #4, computing a percent error of your findings using this formula: % error = measured value - accepted value x 100 accepted value use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. need asap

Two people each hold the end of a rope and create waves by moving their arms up and down. this wave is best classified as a transverse wave because a) both the rope particles and the wave are moving in the same direction. b) the wave is moving up and down as the particles of the rope move horizontally. c) the wave is moving horizontally as the particles of the rope move up and down. eliminate d) the wave is moving in a parallel direction with the motion of the person's arms.
