Answer:

C. Molding of cheese.

Explanation:

Hello,

In this case, both mixing and grating of cheese are physical changes as the composition of the cheese does not change. In contrast with the aforesaid options, molding of cheese is associated with the growing metabolic process of mold as it is chemically processing the cheese to both grow and produce other types of metabolites which are quite different than the initial cheese's components.

Best regards.

Which of these chemical formulas — Cl2 , KCI, Ar, NO2– represents both an element and a molecule ?

Tasya [4]

The answer is: Cl2.

Chlorine is diatomic molecule made of two chlorine atoms.

Diatomic molecules are molecules made of two atoms.

They can be homonuclear (molecule made of two atoms of the same element) and heteronuclear (molecule made of two different atoms).

Chlorine (Cl) is halogen element.

Halogen elements are in group 17: fluorine (F), chlorine (Cl), bromine (Br) and iodine (I). They are very reactive and easily form many compounds.

1. A light bulb is filled with 3.54 g of argon at 25 C and 725 mmHg. What is

Ugo [173]

Answer: The volume of given gas is 2.27 L.

Explanation:

Given: Mass = 3.54 g

Temperature = $25^{o}C$ = (25 + 273) K = 298 K

Pressure = 725 mm Hg (1 mm Hg = 0.00131579) = 0.95 atm

As moles is the mass of substance divided by its molar mass.

So, moles of argon (molar mass = 40 g/mol) is as follows.

$Moles = \frac{mass}{molar mass}\\= \frac{3.54 g}{40 g/mol}\\= 0.0885 mol$

Formula used to calculate the volume of given gas is as follows.

PV = nRT

where,

P = pressure

V = volume

n = no. of moles

R = gas constant = 0.0821 L atm/mol K

T = temperature

Substitute the values into above formula as follows.

$PV = nRT\\0.95 atm \times V = 0.0885 mol \times 0.0821 L atm/mol K \times 298 K\\V = 2.27 L$

Thus, we can conclude that the volume of given gas is 2.27 L.
