avanturin [10]3 years ago
6 0

Answer:

True

Explanation:

Law of conservation of mass states that for a closed system the mass have to remain constant in time, so for chemical equations you need to ensure that is balanced. Otherwise if you do not balance the equation you would not know how much of a compound to weight for a certain reaction, or you weight an incorrect quantity.

A sample of gas has a volume of 20.0 liters at 22.0° C. If the pressure remains constant, what is the volume at 100.0° C?
miv72 [106K]
The problem applies Charles' law since constant pressure with varying volume and temperature are given. Assuming ideal gas law, the equation to be used is \frac{ V_{1} }{ T_{1} }=\frac{ V_{2} }{ T_{2} }. We make sure the temperatures are expressed in Kelvin, hence the given added with 273. The volume 2 is equal to 25.2881 liters.

VladimirAG [237]

Answer:

In sea water;

The salt is the solute while the water is the solvent

In soda water;

The water is the solvent, the carbon dioxide is the solute

In air;

The nitrogen is the solvent while the oxygen and the other substances in small amounts are the solutes

Explanation:

A solution is a homogeneous mixture of two or more substances which includes a solvent and a solute. A solute in a solution is dissolved in the solvent of the solution.

Therefore, the solvent is the major part of a solution as it takes in the solvent to form the solution.

In sea water, a solution with a high concentration of salts

The salt is the solute while the water is the solvent

In soda water,  which is a mixture of CO₂ in water,

Here we have in the soda solution, the water is the solvent while the carbon dioxide is the solute

The water is the solvent, the carbon dioxide is the solute

Air a solution made up by a mixture of Nitrogen 78%, oxygen 21%, and small amount of water carbon dioxide and argon

The nitrogen is the solvent while the oxygen and the other substances in small amounts are the solutes.
