What volume does 4.24g of argon gas occupy at 58.2 degrees celcuis and 1528torr

V = 1.434 L

Explanation:

Given data:

Mass of argon = 4.24 g

Temperature = 58.2 °C

Pressure = 1528 torr

Volume = ?

Solution:

58.2 °C = 58.2 + 273 = 331.2 K

1528/760= 2.01 atm

Number of moles:

Number of moles = mass/molar mass

Number of moles = 4.24 g / 39.948 g/mol

Number of moles = 0.106 mol

Volume:

PV = nRT

V = nRT/P

V =  0.106 mol ×0.0821. atm. L. mol⁻¹. K⁻¹ × 331.2K/ 2.01 atm

V = 2.88 atm L/ 2.01 atm

V = 1.434 L

b) mutualism

hope this : )

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.
