Assume that thermal decomposition of mercuric oxide, HgO, follows first-order kinetics. It can be followed by the production of oxygen gas as a product: 2HgO(s)2Hg(l)+O2(g) At a particular temperature, k=6.02104s1. If 1.00gram of HgO were present initially, how long would it take to produce a1.00mL of O2(g) at STP; b10.0mL of O2(g) at STP? STP = standard temperature and pressure for a gas.

Differential EQN: Bruce Wayne analyzes a kryptonite in order to prepare if ever Clark Kent becomes rogue. The former studieda kryptonite and found that it decomposes at a rate proportional to the quantity of kryptonite present.Suppose that it is found that in 25 years approximately 1.1% of a certain quantity of kryptonite hasdecomposed. Determine how long it will take until 50% of the original amount of kryptonite dissipates. pls. provide complete solution with explenation. the formula we use is : dx/dt=kx

hello, i sent this question before but the answer you rpovided for both wasnt right and i couldnt undertstand how you got the answer. can you please show me a handwritten solution for better understanding. 1a) The decomposition of ethanol at some constant temperature (above 500°C), over a copper surface, C2H5OH(g) CH3CHO(g) + H2(g) was studied by monitoring the total pressure with time.The following data were obtained: t (s) Ptotal (torr) 0 120 45 131 139 154 233 177 376 212 380 213 What will be the total pressure at t = 462 s? 1b) What is the rate constant (k)?(Include appropriate units.)
Collision theory depends on knowing the fraction of molecular collisions having at least the kinetic energy Ea along the line of flight. What is this fraction when (i) Ea = 20 kJ mol−1, (ii) Ea = 100 kJ mol−1 at (1) 350 K and (2) 900 K?
The first step in the heterogeneoushydrogenation of ethylene is adsorption of theethylene molecule on a metal surface. One proposed explanation for the “sticking” of ethylene to a metalsurface is the interaction of the electrons in the C—C π bond with vacant orbitals on the metal surface. (a) If thisnotion is correct, would ethane be expected to adsorb to a metal surface, and, if so, how strongly would ethane bindcompared to ethylene? (b) Based on its Lewis structure,would you expect ammonia to adsorb to a metal surfaceusing a similar explanation as for ethylene?
