H2SO4(aq) + CaCO3(s) > H2O(1) + CO2(g) +CaSO4(s)
2HClO(aq) + Ca(OH)2(aq) > 2H2O(l) +Ca(ClO)2(aq)

Jose and eric were given four samples in lab. the results of their analysis are shown in the table. based on the data they collected, which sample is most likely a metal?

How many moles of bromine are needed to produce 3.23 moles of potassium bromide

High-pressure liquid chromatography (hplc) is a method used in chemistry and biochemistry to purify chemical substances. the pressures used in this procedure range from around 500 kilopascals (500,000 pa) to about 60,000 kpa (60,000,000 pa). it is often convenient to know the pressure in torr. if an hplc procedure is running at a pressure of 1.03×108 pa , what is its running pressure in torr?
