An experiment was performed for the decomposition of phosgene gas to form carbon dioxide and chlorine at 527 degrees celsius. The equilibrium constant for the reaction at 527 degrees celsius, is 4.63 × 10^-3. initially, only phosgene was present in the reaction vessel. At equilibrium, the concentration of phosgene at 527 degrees celsius was 0.0864molL-1. calculate the equilibrium concentration of carbon monoxide

Rocks, as they are compressed, begin forming mountains above the earth's surface when two continental plates converge. the continental crust increases in depth as the mountains grow above. the himalayan mountains formed at a convergent plate boundary in this manner. the rocks are smashed together causing them to due to the intense heat and pressure from the colliding plates and eventually forming rock. a) melt; igneous b) layer; sedimentary c) recrystallize; metamorphic d) melt into the earth's interior; metamorphic

Which of the following is an example of physical change not a chemical change? a) a log gives off heat and light as it burns. b) a tree stores energy from the sun in its fruit. c) a penny lost in the grass slowly changes color. d) a water pipe freezes and cracks on a cold night.
