Assuming we have a 100g sample, the mass of each element is as follows:
C: 74 g
H: 7.4 g
N: 8.6 g
O: 10 g
Next, we calculate the moles of each by dividing the mass of each element by its molar mass:
C: (74 / 12) = 6.17
H: (7.4 / 1) = 7.4
N: (8.6 / 14) = 0.61
O: (10 / 16) = 0.625
Now, we take the smallest value to determine the ratio:
C: 10
H: 12
N: 1
O: 1
Thus, the empirical formula can be expressed as
C10H12NO
The change in temperature can be expressed as:
By substituting in the known values, we arrive at:
Thus, we obtain the required answer.
As the ball descends down the hill, its potential energy diminishes while its kinetic energy rises.
The ball's potential energy will decrease as it moves down the slope, and its kinetic energy will experience an increase.
Kinetic energy refers to the energy possessed by an object in motion.
K. E = 
m v²
where m is the mass of the ball
and v represents the ball's velocity.
Potential energy is the energy associated with an object's position as it traverses down a slope, expressed as:
P.E = mgh
with m as the mass of the ball,
g as gravitational acceleration, and h as the height.
It is clear that as the object descends, its height decreases, while its velocity increases.

The conversion of -70 degrees Celsius results in 9/5 x C + 32 = 158 degrees Fahrenheit. CO2 transitions to solid state at -108.5 degrees Fahrenheit, indicating that at -70 degrees Celsius, it will be in the state commonly known as 'dry ice'.
