Does this system of equations have one solution no solutions or an infinite number of solutions x - 2y equals -6 and x-2y equals 2?
x - 2y = -6 x - 2y = 2 subtract the 2nd equation from the 1st equation 0 = -8 false Therefore, the system of the equations has no solution.
The diagonals of a rhombus are congruent true or false?
False
True or false a chemical is always the same thing as an element?
FALSE
A ray contains no endpoints?
A ray has no endpoints true or false
Is pure gold 22 carrot true or false?
False. Pure gold is 24 karat.
Is unsaturated solutions will not dissolve more solute true or false?
False. Unsaturated solutions have not reached their maximum solute concentration and can dissolve more solute.
Are all solutions must be in the liquid state?
No, solutions can exist in different states of matter, not just in the liquid state. Solutions can exist in the solid, liquid, or gas state depending on the solvent and solute involved in the mixture.
What are the differences between true and false solutions?
A true solution is homogeneous, that is the same all the way through, and you can't see the solute particles nor filter them out. A false solution is properly called a suspension or colloidal suspension. They are heterogeneous and you may or may not be able to see the solid pieces. Colloidal suspensions scatter light.
Is all mixtures are solutions true or false?
False. As an example wet sand is a mixture of water and sand, but it is not a solution as the two substances remain as distinct phases.
Is it true or false that all mixtures are solutions?
True. A homogeneous mixture is a mixture that has the same amount of solute throughout the solution. And since, in order to be defined a homogeneous mixture, a solvent and a solute have to be involved, the answer is true. An example of a homogeneous mixture is store-bought milk.
What is a false solution?
In chemistry, a false solution is a mixture of substances that appears to be a homogeneous solution but actually contains insoluble particles that are not visible to the naked eye. False solutions can arise when a solute is added to a solvent but does not dissolve completely, resulting in the formation of tiny particles or aggregates of particles that remain suspended in the solvent. False solutions can be problematic in chemistry because they can lead to inaccurate measurements of concentration and other properties of the mixture. For example, if a false solution is used to prepare a dilute solution, the concentration of the solute in the resulting mixture may be incorrectly calculated, leading to errors in experimental results. False solutions can also cause problems in industrial processes, such as filtration or crystallization, where the presence of suspended particles can interfere with the efficiency of the process. To avoid false solutions, it is important to ensure that solutes are completely dissolved in the solvent before preparing a mixture, and to use appropriate methods, such as filtration, to remove any insoluble particles that may be present.
Would Solubility tell you how fast a solute will dissolve true or false?
False. Solubility is a measure of how much solute can dissolve in a given solvent at a specific temperature and pressure, but it does not indicate how fast the solute will dissolve. The rate of dissolution depends on factors like surface area, stirring, temperature, and concentration gradient.
Concentration is always measured in grams of solute divided by liters of solution?
Concentration can be measured in various units depending on the solute and solvent. Common units include molarity (moles of solute per liter of solution), mass/volume percent (grams of solute per 100 mL of solution), and molality (moles of solute per kilogram of solvent). The appropriate unit depends on the specific experimental conditions and the properties of the solute and solvent.
Is salt a solute in seawater true or false and why?
True. Salt is a solute in seawater because it is dissolved in the water to form a solution. Seawater is a mixture of salt (solute) and water (solvent).
A supersaturated solution contains less dissolved solute than a saturated solution at the same temperature?
In a supersaturated solution, the solute concentration exceeds the saturation point at that temperature. This is achieved by dissolving the solute in a hot solution and then slowly cooling it down without allowing the excess solute to precipitate out. A saturated solution has the maximum amount of solute that can be dissolved at a given temperature.
Is the substance that gets dissolved the solvent?
No, the substance that gets dissolved is the solute. The solvent is the substance in which the solute dissolves.
Is is true or false thae you can make concentrated solution more dilute by adding solvent?
The statement is true. Solvent is what you dissolve a solute in. In chemistry, your solvent is usually going to be water. So, if you have a concentrated solution and you pour some more water into it, you're diluting the solution.
