275 L of krypton gas is held at 225 K. What is the volume when the temperature is increased to 500.K? 124 L

611 L

500. L

409 L

The temperature increases from 293 K to 313 K. It follows that the volume increases and the . T . factor must be greater than 1. We can visually summarize the Charles’s law solution as follows: Conceptual Solution. A 275 L helium balloon is heated from 20 °C to 40 °C. Calculate the final volume assuming the pressure remains constant.

i think that is the right

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
