Liquid level in a tank is determined by measuring the p ink is determined by measuring the pressure at the bottom of the tank. a calibration curve is pren in curve is prepared by filling the tank to several known levels, reading the bottom bourdon gauge and plotting level versus pressure. a calibration experiment calibration experiment was done using a liquid with a specific gravity of 0.9, but the same tank is used to store another liquid with a specific gravity of 0.75. if the storage liquid level reaches the maximum height of the tank (h = 10 m), what value will be read from the calibration curve?

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
