Given that 56 grams of an ideal gas occupies 6.9 litres (dm) at STP (Standard temperature a
nd pressure, OC and 101,325 Nm), what is its
volume at 100°C and a pressure of 76.0 cm of mercury? Do not use the
general gas equation to solve this problem.

​

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.

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.
