True or false seawater contains dissolved substance that give it a salt taste?
True. Seawater contains dissolved substances, primarily salt, which gives it a characteristic salty taste. The most abundant salt in seawater is sodium chloride, along with other minerals and trace elements. This combination of dissolved substances contributes to the overall flavor of seawater.
Is solution a mixture in which the components are evenly distributed throughout?
Yes, a solution is a mixture where the components are evenly distributed at the molecular level. This means that the solute (substance being dissolved) is uniformly dispersed in the solvent (the dissolving medium).
Is that true or false distillation can separate dissolved substances through physical changes?
True, distillation is a separation process that utilizes differences in boiling points to separate components in a mixture. When a solution is heated, the component with the lowest boiling point will vaporize first, allowing it to be collected separately from the other components. This physical change enables the separation of dissolved substances in a solution.
A carbonated beverage that contains carbon dioxide gas in a solution is an exampple of a liquid-gas system... True or False?
True. A carbonated beverage is a liquid-gas system because it contains dissolved carbon dioxide gas in the liquid beverage.
Is rootbeer a solution?
Root beer is not a true solution; it is a carbonated beverage that contains a mixture of water, sugar, flavorings (such as sassafras or sarsaparilla), and carbonation. In a solution, the solute is completely dissolved in the solvent, creating a homogeneous mixture. In root beer, the various components can remain undissolved or suspended, making it more of a colloidal mixture than a true solution.
Is it true that lightning can make plasma?
Yes. It is the plasma that makes the bolt visible.
Is it true that Movement of water across the plasma membrane depends on the relative concentration of solutes or dissolved substances?
Yes, the movement of water across the plasma membrane, known as osmosis, depends on the relative concentration of solutes. Water will move from an area of lower solute concentration to an area of higher solute concentration in an attempt to balance the solute concentrations on both sides of the membrane.
Is a milkshake a solute?
No, a milkshake is not a solute; it is a colloidal mixture or suspension of various ingredients, including milk, ice cream, and flavorings. In a solution, a solute is the substance that is dissolved in a solvent, while a milkshake contains particles that do not fully dissolve but remain mixed. Thus, the components of a milkshake retain their distinct properties and do not form a true solution.
Is it true that plasma has no definite shape and can flow?
Yes. In this sense, a plasma is similar to a gas.
Do eukaryotes have a true nucleus?
Yes, eukaryotes have a true nucleus that contains their genetic material (DNA). The nucleus is membrane-bound and separates the genetic material from the rest of the cell's components.
Is chicken broth a solution?
Chicken broth is not a true solution; it is a mixture. A solution is a homogeneous mixture at the molecular level, where one substance is completely dissolved in another. In contrast, chicken broth contains various components, such as water, fats, proteins, and solid particles from the chicken and vegetables, resulting in a heterogeneous mixture. While certain components may dissolve in water, the broth itself retains a more complex structure.
Is Plasma has good conductor of electricity?
True.
