Answer:
B. N3H
Explanation:
because I learned that alot
The kinetic energy causes the air molecules to move faster and they impact the container walls more frequently and with more force. The kinetic energy of the gas molecules increases, so collisions with the walls of the container are now more forceful than they were before. As a result, the pressure of the gas doubles.
Answer:
a) 1.269 × 10^-7 m
b) This wavelength occurs in the ultraviolet region of the electromagnetic spectrum
Explanation:
The energy required to break the bond= energy of the incident photon
E= 941 × 10^3/6.02 × 10^23 = 1.56 ×10^ -18 J
From
E= hc/λ
h= Plank's constant
c= speed of light
λ= wavelength of incident photon
λ= hc/E
λ= 6.6 ×10^-34 × 3 ×10^8/1.56 ×10^ -18 J
λ= 1.269 × 10^-7 m
b) This wavelength occurs in the ultraviolet region of the electromagnetic spectrum
Answer: solid chemicals in waterharden and form rocks
Explanation:
<h3>
Answer:</h3>
327° C
<h3>
Explanation:</h3>
The initial temperature of the gas is 27°C
We need to find the final temperature.
If we assume the initial pressure is y
The final temperature will be 2y
Using the pressure law;
Therefore,
Therefore, the new temperature is 600 K or 327° C
