Since the soccer ball is heating up the air in the ball will expand, which will cause the ball to grow in size and it will have more volume and pressure but less density. (if you put a soccer ball in water it'll float since it has less weight from the air, that's it's density) hope this helps. <3
Yes! Becuz baking soda is strong and if you mix it with any liqued it makes BUBBLES
<u>Answer:</u>
The correct answer option is a) collisions between the particles and surrounding molecules.
<u>Explanation:</u>
The collisions between the particles and surrounding molecules causes the Brownian motion of particles in a colloid.
Brownian motion is the irregular movement of the microscopic particles in a fluid which bombard into each other.
It basically is the result of the molecules of a dispersion medium colliding with the dispersed particles of the phase.
<u>Answer:</u> The volume of water vapor produced is 26.6 L.
<u>Explanation:</u>
To calculate the volume of water vapor when number of moles changes , we use Avogadro's Law. This law states that the volume is directly proportional to the number of moles of gas if temperature and pressure remains constant.
Mathematically,
![V\propto n\\\\\frac{V_1}{n_1}=\frac{V_2}{n_2}](https://tex.z-dn.net/?f=V%5Cpropto%20n%5C%5C%5C%5C%5Cfrac%7BV_1%7D%7Bn_1%7D%3D%5Cfrac%7BV_2%7D%7Bn_2%7D)
where,
= Initial volume and number of moles
= Final volume and number of moles
For the given chemical reaction:
![CH_4(g)+2O_2(g)\rightarrow CO_2(g)+2H_2O(g)](https://tex.z-dn.net/?f=CH_4%28g%29%2B2O_2%28g%29%5Crightarrow%20CO_2%28g%29%2B2H_2O%28g%29)
By Stoichiometry,
1 mole of methane reacts with 2 moles of oxygen gas to produce 1 mole oc carbon dioxide and 2 moles of water vapor.
We are given:
![V_1=13.3L\\n_1=1mole\\V_2=?L\\n_2=2mole](https://tex.z-dn.net/?f=V_1%3D13.3L%5C%5Cn_1%3D1mole%5C%5CV_2%3D%3FL%5C%5Cn_2%3D2mole)
Putting values in above equation, we get:
![\frac{13.3L}{1mol}=\frac{V_2}{2mol}](https://tex.z-dn.net/?f=%5Cfrac%7B13.3L%7D%7B1mol%7D%3D%5Cfrac%7BV_2%7D%7B2mol%7D)
![V_2=26.6L](https://tex.z-dn.net/?f=V_2%3D26.6L)
Hence, the volume of water vapor produced is 26.6 L.
