A gas exerts 59.3 kPa on its container at 25.0 °C. What temperature is needed to increase the pressure to 71.0 kPa? * 249 K O 2.80 x 10-3 K О 14.1 К О 357 К

1.) This reaction occurs in large test tube at 32.0oC: 2 Al (s)  + 3 H2SO4(aq) ---> 6 H2 (g)  +  Al2(SO4)3 (aq) A tube going through the stopper of the test tube feeds into a graduated cylinder that has been inverted in a tub of water.  At the end of the reaction, the total pressure of gas in the inverted cylinder is 435. torr, and the volume of gas collected is 455. mL. What mass of aluminum must have reacted?     P.s- please show how you got it. I get confused with it

When limestone (solid CaCO3) is heated, it decomposes into lime (solid CaO) and carbon dioxide gas. This is an extremely useful industrial process of great antiquity, because powdered lime mixed with water is the basis for mortar and concrete - the lime absorbs CO₂ from the air and turns back into hard, durable limestone. Suppose some calcium carbonate is sealed into a limekiln of volume 550. L and heated to 910.0 °C. When the amount of CaCO3 has stopped changing, it is found that 567. g have disappeared. P Calculate the pressure equilibrium constant K, this experiment suggests for the equilibrium between CaCO3 and CaO at 910.0 °C. Round your answer to 2 significant digits. Note for advanced students: it's possible there was some error in this experiment, and the value it suggests for K does not match the accepted value. K-0 P
