Answer options with 4 options
A.
Container 1 is a closed system because a gas was produced. Gases do not have mass.
B.
Container 1 is an open system because a gas was produced. Gases make things lighter.
C.

Container 2 is a closed system because the mass did not change even

though the volume changed.

<h3>What is a Closed system?</h3>

A closed system is the type of system which prohibits the transfer of

matter in and out the system.

In a closed system , the mass of the matter present is always the same

regardless of the changes which occurred which is why option D is the

most appropriate option.

The nonvolatile, nonelectrolyte testosterone, C19H28O2 (288.40 g/mol), is soluble in benzene C6H6. Calculate the osmotic pressur
dolphi86 [110]

Answer:

3.824 atm

Explanation:

From the ideal gas equation

P = mRT/MW × V

m is mass of testosterone = 12.9 g

R is gas constant = 82.057 cm^3.atm/mol.K

T is temperature of benzene solution = 298 K

MW is molecular weight of testosterone = 288.40 g/mol

V is volume of benzene solution = 286 ml = 286 cm^3

P = 12.9×82.057×298/288.4×286 = 3.824 atm

Why don’t all of the particles in an atom contribute to the mass?
kotegsom [21]

Answer:

Explanation:

The mass of an atom is dependent on its number of protons and neutrons. Electrons have mass, but are too light in comparison to protons and neutrons to contribute towards the overall mass. Their relative mass is about 1/1840 compared to 1 for protons and neutrons, and therefore are not counted in the mass.

Hope this helped!

The<br>of a chemical reaction is the maximum amount of product that can be produced​
Troyanec [42]

Answer= Maximum amount of product that could be obtained under ideal conditions from a given amount of reactants.

Explanation:

The theoretical yields is the ideal maximum amount of a product that can be produced during a chemical reaction while the limiting reactant is the reactant that determines the maximum amount of product that can be formed. mitgliedd1 and 61 more users found this answer helpful.
