One gram-mole of methyl chloride vapor is contained in a vessel at 100°C and 10atm.(a) Use the ideal-gas equation of state to es
777dan777 [17]

Answer:

a) The volume of the system is 3.062 Liters.

b) Percentage error results from assuming ideal-gas behavior is 9.36%.

Explanation:

a)

Using ideal gas equation:

PV = nRT

where,

P = Pressure of gas = 10 atm

V = Volume of gas = ?

n = number of moles of gas = 1 mol

R = Gas constant = 0.0821 L.atm/mol.K

T = Temperature of gas = 100°C = 100+273K=373 K

Putting values in above equation, we get:

(10 atm)\times V=1 mol\times (0.0821L.atm/mol.K)\times 373 K

V=\frac{1 mol\times (0.0821L.atm/mol.K)\times 373 K}{10 atm}

V = 3.062 L

The volume of the system is 3.062 Liters.

b)

Volume of the container = V' = 2.8 L

System volume = V = 3.062 L

Percentage error of volume:

To calculate the percentage error, we use the equation:

\%\text{ error}=\frac{|\text{Experimental value - Accepted value}|}{\text{Accepted value}}\times 100

=\frac{|3.062L-2.8 L|}{2.8 L}\times 100=9.36\%

Percentage error results from assuming ideal-gas behavior is 9.36%.

How is the concept of “heat” related to the law of conservation of energy?
musickatia [10]

Explanation:

The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it's added from the outside. ... is the heat added to, or removed from, the system.

Which of these most likely represents a chemical change?
Sauron [17]

Answer: Option (b) is the correct answer.

Explanation:

An enzyme called salivary amylase helps in the breakdown of sugar into small particles. This enzyme affects the sugar for a small period of time in the mouth.

Once, salivary amylase reaches the stomach it becomes inactive because of the acid present in stomach. Further, this acid breaks the sugar molecules and these molecules are sent to the intestine for further reaction.

Thus, we can conclude that sugars digested by saliva is a chemical change.
