The decomposition of PCl5 is shown below:
PCl5(g)⇌PCl(g) + Cl(2)
Kc 3 = 0.029 at 85°C
Find out if the reaction proceeds forward, backward, or if the system is at equilibrium when a 1 liter
container is filled with 0.4 mole PCl5, 0.5 mole PCl3, and 0.2 mole Cl2.
Do the following, sketch the normal distribution/s given the following conditions.
1.Two normal distributions within the same mean
and standard deviation.
2. three normal distribution in one horizontal axis
with the
same meant but with different standard
deviation.
3. A normal curve with shaded area within a
standard deviation of the mean.
4. A normal curve with a mean, M = 76 and standa
deviation o=1
5. A normal curve with a mean, M=0 and
standard deviation
A man 6 ft. tall walks away from a lamp post 18 ft. high at the rate of 4 ft. per second. How fast does
the shadow of the man lengthen?
If we start with 0.00240 M NOBr, what concentration of NOBr will remain after 5.00 minutes of reaction? The reaction is second order.

A ladder 5 meters long is leaning against the wall. The bottom is initially 3.5 meters away from the
wall. You are pushing it towards the wall at a rate of 0.20 m/s. How fast is the top of the ladder moving
up the wall 12 seconds after you start pushing?

Write a program using string functions that determine if the input word is a palindrome. A
palindrome word is a word that produces the same word when it is reversed.
Sample Input/output Dialogue:
Enter a word: AMA
Reversed: AMA
“It is Palindrome”
Enter a word: MAYOR
Reversed: ROYAM
You burn a 15g jellybean to warm 50 mL of water, which increases the temperature of the water 25 °C. How many calories of heat are transferred from the jellybean to the water? Assume there is no heat loss.
