I have calculated pressure in container one and that is p1 = 342817.92 Pa, and in container two p2 = 326979.2275 Pa. Then I have substracted this two values which gives me 15838.6925 Pa. After that I have divided this value with two, to figure out how much do I have to decrease pressure in container 1, and that gives me 7919.34625 Pa. You cannot generally ...

Unfortunately this is not feasible Current catalytic converters are designed to remove noxious pollutants from exhausts. Things like carbon monoxide (poisonous) and nitrogen oxides (noxious and irritating). The trouble with doing this for carbon dioxide is fundamental. Carbon dioxide and water are the ultimate products of combustion of hydrocarbons because ...

Chalk cannot at given conditions explode chemically, spontaneously turning into other compounds. It could locally "explode" mechanically as consequence of mechanical stress caused by thermal dilation due changes to temperature. But calling it explosion would be very much exaggerated. It would be rather just cracking. There is a way such cracking ...

Nothing would happen. The reaction would not shift to produce more product. Let's suppose you allow this reaction to equilibrate in a sealed container. Equilibrate means you've reached the equilibrium value for $p_{\text{O}_2}$ at that temperature. Now further suppose you were able to remove all the product without changing the free volume (say you ...

I am using a saturated sodium chloride solution as an example here because it is more common and easier to reproduce at home. This system is at equilibrium, with salt dissolving and crystallizing at the same rate. If you take away the solid NaCl from a saturated solution, both the forward and the reverse reactions stop. Obviously, salt crystals are no longer ...

Let's compare the two compounds. Solubility: Both compounds are miscible with water, so there is no difference. With the straight chain, 1-propanol may be slightly more lipophilic, and thus better able to act as a surfactant. However, 1-propanol is a really poor surfactant. Volatility: Isopropanol has a lower boiling point (82.5 degrees C) than 1-propanol (...

It might help to think of the system as containing three phases: $\ce{P4(s)}$, $\ce{O2(g)}$ and $\ce{P4O10(s)}$. As long as the pressure, temperature and compositions of each phase remain constant (and P,T and chemical potentials across phases are in equilibrium i.e. equal), we can alter their extents arbitrarily without altering the condition for ...

Depends on how accurately performed is each measurement. One would have to take into account precision of ruler and asymmetry of cube, for example, in the first case, and adhesion of water to cube and cylinder, causing meniscus and other errors. However, in some cases, ruler measurement would be far more accurate than water displacement: Archimedes would ...

Gypsum is the major constituent of plaster. It is non-toxic. Our lungs are capable of filtering out particles greater than 50 micrometers in diameter. Any dust finer than that is potentially dangerous.
