I don't know what the options were but a material that is very likely going to be challenging to recognize under a microscope as a mixture is a homogeneous mixture. A homogenous mixture is uniform and thus hard to recognize as a mixture. An example is water!

Answer:

Pressure = 4.81atm

Explanation:

Pressure = ?

Temperature = 20°C = (20 + 273.15)K = 293.15K

Volume = 2.50L

R = 0.082J/mol.K

n = 0.5mol

From ideal gas equation,

PV = nRT

P = pressure of the ideal gas

V = volume the gas occupies

n = number of moles of the gas

R = ideal gas constant and may varies due to unit of pressure and volume

T = temperature of the ideal gas

PV = nRT

Solve for P,

P = nRT/ V

P = (0.5 * 0.082 * 293.15) / 2.50

P = 12.01915 / 2.50

P = 4.807atm

P = 4.81atm

The pressure of the ideal gas is 4.81atm

A copper atom has a mass of 1 06 times 10^-22 g and a penny has a mass of 2.5 g. Use this information to answer the questions be
amm1812

Answer:

Mass of 1 mole of copper is 63.83 g.

0.03916 moles of copper atoms have a mass equal to the 2.5 grams of copper penny.

Explanation:

Mass of 1 copper atom,m = 1.06\times 10^{-22} g

1 mole = 6.022\times 10^{23} atoms

Mass of 1 mole of copper :

= 6.022\times 10^{23} atoms\times 1.06\times 10^{-22} g=63.83 g

Mass of 1 mole of copper = 63.83 g

Mass of copper penny = 2.5 g

Atomic mass of copper = 63.83 g/mol

Moles of copper in 2.5 g of copper penny:

\frac{2.5 g}{63.83 g/mol}=0.03916 mol

0.03916 moles of copper atoms have a mass equal to the 2.5 grams of copper penny.
