1. If you blow up a balloon with 0.5 moles of gas, it has a volume of 11.2 L. What will the volume be if you fill it with 2.0 moles of gas?

2.Using the combined gas law: A sample of gas occupies a volume of 0.652 L at 313K and 0.90 atm. What volume will the sulfur dioxide occupy at STP?

3. Think about the previous question. With the temperatures and pressures provided, should the volume increase or decrease. Explain your reasoning.

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

  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-
