What is difference between melting point and drop melting point?

The melting point is the temperature at which a solid substance transitions to a liquid state. The drop melting point is a method of determining the melting point where a small amount of the substance is heated until it melts and then allowed to drop onto a solid surface to observe the melting point. Drop melting point is often used when the substance being tested has a high melting point or when observing the melting process is critical.


What would be observed from an aqueous mixture of magnesium chloride and sodium hydroxide?

You would observe precipitation of magnesium hydroxide.


What is the controlled variable of melting ice?

The controlled variable of melting ice is the temperature at which the ice is exposed. By keeping the temperature constant, researchers can observe the effects of other factors, such as pressure or salinity, on the melting process. Controlling this variable ensures that any changes in the ice melting are due to the specific factor being studied rather than fluctuations in temperature.


What is homogenouse mixture?

a homogenious mixture is a mixture that is formed by adding substances together but do not combine, an example of this is a salad. you can observe it, and see what is in your salad.but a heterogenious mixture is where you cannot clearly see whats inside. like a cake, you dont know whats inside because the ingrediances are all baked in.


You can tell whether a mixture is a solution or a suspension when you?

observe that the particles in a solution are uniformly distributed and do not settle over time, while the particles in a suspension settle out and form a distinct layer.

What did you observe while benzic acid-salt mixture is melting?

When a benzoic acid-salt mixture melts, you may observe the formation of a clear or slightly colored liquid. The melting point may be lower compared to the individual components, indicating a eutectic mixture. Any impurities present in the mixture may affect the melting behavior and appearance of the molten material.


Can you observe the melting point of NaCl?

The melting point of sodium chloride is 801 0C.


If you heat too fast when determining melting point will you observe a lower or higher melting point than true value?

If you heat too fast when determining melting point, you may observe a lower melting point than the true value. This is because rapid heating can lead to the formation of a supersaturated solution, causing the melting point to appear lower due to impurities not having enough time to properly dissolve or crystallize.


Is the difference between a pure substance and a mixture easy to observe?

No.


How many sets of properties do you need to observe in order to classify a material as a homogeneous mixture?

To classify a material as a homogeneous mixture, you typically need to observe at least two sets of properties. These properties should indicate that the components of the mixture are uniformly distributed and that there are no visible differences between different parts of the mixture.


What do you observe if dilute hydrochloric acid is added to the mixture of iron and sulphur?

ironchloride and sulphuric acid


How many sets of properties do you need to observe in order to classify a material as a heterogeneous mixture?

You need to observe at least two sets of properties to classify a material as a heterogeneous mixture. This is because a heterogeneous mixture is a combination of different substances that can be distinguished by their properties, such as size, color, and phase. By observing multiple sets of properties, you can confirm that the mixture is not uniform in composition.


What is difference between melting point and drop melting point?

The melting point is the temperature at which a solid substance transitions to a liquid state. The drop melting point is a method of determining the melting point where a small amount of the substance is heated until it melts and then allowed to drop onto a solid surface to observe the melting point. Drop melting point is often used when the substance being tested has a high melting point or when observing the melting process is critical.


What did you observe when concentrated sulphuric acid was added to the reaction mixture?

I think it makes the equation to be more balanced


Observe and thinkof ways on how you can change these solid?

Generally a solid become a liquid by melting or a gas by sublimation; but not all the solids can be melted.


What are the independent variables in an ice melting experiment?

The independent variables in an ice melting experiment could include factors that might affect the rate of ice melting, such as temperature, surface area of the ice cube, presence of salt or other substances on the ice, or the ambient humidity. These are variables that can be manipulated by the researcher to observe their impact on the melting process.
