5.88 The thermal decomposition of ethylene occurs in many industrial contexts, for example, during ethylene transit in pipelines, formation of polyethylene, drying of the gas, and sep arating it from impurities. The decomposition reaction is (b) How does the PV / R * T value of C*H_{4} compare to that in Figure 5.18? Explain.

(a) What is the final pressure of the confined gas (ignore the vol ume of graphite and use the van der Waals equation)?

Assume that decomposition begins at 10 degrees * C and 50.0 atm with a gas density of 0.215g / m * L and the temperature increases by 950 K.

CH 2 =CH 2 (g) longrightarrow CH 4 (g)+C(gr epsilon )

Imagine if during the cathode ray experiment, the size of the particles of the ray was the same as the size of the atom forming the cathode. which other model or scientific observation would have also been supported? 1. this would support dalton's postulates that proposed the atoms are indivisible because no small particles are involved. 2. this would support bohr's prediction about electrons moving in orbits having specific energy. 3. this would support bohr's prediction about electrons being randomly scattered around the nucleus in the atom. 4. this would support dalton's postulates that proposed that atoms combine in fixed whole number ratios to form compounds.
