A because it is the only one that a formula doesnt tell
• Before the balloon was placed inside the hot water, the pressure was the same inside and outside the balloon. The hot water raised the kinetic energy of the air molecules inside the balloon, expanding the balloon, through thermal expansion.
• (1) the pressure of air inside the balloon increased, (2) the volume of the inside of the balloon increased as well, and (3) the temperature of the balloon increased. Note that pressure and volume are inversely proportional, and pressure and temperature are directly proportional. Therefore as the temperature increases, the pressure inside will increase, causing an increase in the volume. At a certain point though the volume will increase too much as to cause a significant decrease in pressure.
• The air molecules will gain kinetic energy, hence (1) increasing the molecules's speed, and (2) heating the air molecules.
Answer:
The answer to your question is K = 1.48
Explanation:
Balanced chemical reaction
Br₂ + I₂ ⇒ 2IBr
Process
1.- Calculate the concentration of each of the reactants
[Br₂] = 0.6 mol / 1 L
= 0.6 M
[I₂] = 1.6 mol / 1 L
= 1.6 M
[IBr] = 1.19 M
2.- Write the equation of the Equilibrium constant
K = [IBr]² / [Br₂][I₂]
-Substitution
K = [1.19]² / [0.6][1.6]
- Simplification
K = 1.4161 / 0.96
- Result
K = 1.48
Answer:
The atoms are vibrating in place.
Explanation:
One of the properties of an ionic substance is the possession of a crystalline structure. As Gerry observed the salt under a microscope, he discovered that it has a crystalline structure. Crystalline salts are all ionic in nature, hence the salt observed by Gerry is an ionic salt.
Solids containing a definite crystalline structure always has their particles vibrating in place. This is immediately evident as Gerry looks at the salt through a microscope.
