The carbon-oxygen single bond in a carboxylic acid
Explanation:
a. Average kinetic energy is directly proportional to absolute Kelvin temperature of a gas.
Yes
b. There are no attractive forces and repulsive forces between gas molecules.
Yes
C. Atoms are neither created nor destroyed by ordinary chemical reactions.
No
d. The volume occupied by all of the gas molecules in a container is negligible compared to the volume of the container
Yes
The kinetic molecular theory is one of such theories used to explain the forces between molecules and the energy they posses.
According to the theory;
- The temperature of gas is proportional to the average kinetic energy.
- Molecules are independent of one another and the force of attraction and repulsion between them is negligible.
- volume occupied by gases is negligible compared to the volume of the container.
Law of conservation of matter states that "atoms are neither created nor destroyed by ordinary chemical reactions".

Answer:
It is A. Because charged particles of solar wind ignite different gases in Earth's atmosphere.
Explanation:
Since the solar wind from the sun is too radioactive for humans (they would die), once the charged particles hit the earth's atmosphere it shows its color. Every element has its own color and once it hits the atmosphere it really starts to show.
Answer:
rate of recrystallization = 4.99 × 10⁻³ min⁻¹
Explanation:
For Avrami equation:
To calculate the value of k which is a dependent variable for the above equation ; we have:
The time needed for 50% transformation can be determined as follows:
![y = 1-e ^{(-kt^n)} \\ \\ e^{(-kt^n)} = 1-y\\ \\ -kt^n = In(1-y) \\ \\ t =[ \dfrac{-In(1-y)}{k}]^{^{1/n}}](https://tex.z-dn.net/?f=y%20%3D%201-e%20%5E%7B%28-kt%5En%29%7D%20%5C%5C%20%5C%5C%20e%5E%7B%28-kt%5En%29%7D%20%3D%201-y%5C%5C%20%5C%5C%20-kt%5En%20%3D%20In%281-y%29%20%5C%5C%20%5C%5C%20t%20%3D%5B%20%5Cdfrac%7B-In%281-y%29%7D%7Bk%7D%5D%5E%7B%5E%7B1%2Fn%7D%7D)
![t_{0.5} =[ \dfrac{-In(1-0.4)}{9.030 \times 10^{-7}}]^{^{1/2.5}}](https://tex.z-dn.net/?f=t_%7B0.5%7D%20%3D%5B%20%5Cdfrac%7B-In%281-0.4%29%7D%7B9.030%20%5Ctimes%2010%5E%7B-7%7D%7D%5D%5E%7B%5E%7B1%2F2.5%7D%7D)
= 200.00183 min
The rate of reaction for Avrami equation is:
rate = 0.00499 / min
rate of recrystallization = 4.99 × 10⁻³ min⁻¹
