Answer:
Anions name is given to a non-metal when it forms an ion, and it has negative charge.
The volume of the brick in cubic centimeters would be:
volume=15 cm x 6.0 cm x 12 cm=1080 cm³
1 m=100 cm
(1 m)³=(100 cm)³ ⇒ 1 m³=1000000 cm³
Therefore:
1080 cm³=1080 cm³ x (1 m³ / 1000000 cm³)=0.00108 m³=1.08 x 10⁻³ m³.
Answer: the volume would be: 0.00108 m³ or 1.08 x 10⁻³ m³
Explanation:
We have,
The most probable speed of an oxygen molecule in the gas phase at room temperature is 450 m/s.
The formula of the most probable speed of a gas molecule is given by :
So,
The RMS speed of the gas molecule is given by :
Use equation (1) in above equation :
It is clear that the RMS speed of the gas molecule is greater than 450 m/s.
