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?

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

the answer is c

tell me if wrong

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
