A sample gas contains 0.1400 mol of C2H4(g) and 0.1400 mol of Br2(g) and occupies a volume of 17.3 L. The following reaction takes place: C2H4(g)+Br2 (g) = > CH2BrCH2Br(g)

calculate the volume of the sample after the reaction takes place, assuming that the temperature and the pressure remain constant.

How many atoms are there in 5.70 mol of mg

Which ocean zone has the most abundant primary producer and why a) the abyssopelagic zone ,du to the absence of light and cold water temperatureb) the bathypelagic zone, due to the absence of light and cold water temperaturec) the mesopelagic zone ,due to uts high light availability and warm water temperature d) the epipelagic zone, due to its high light availability and warm water temperature
