Why refraction does not occur in opaque medium?
Refraction is the bending of the rays of light when it travels from one medium to another... For refraction to occur there should be some difference in the refractive index of the materials.... Refraction can also occur in Opaque medium........
Which state should a reference point be in to be used to determine motion?
The reference point should be stationary, or not moving.
Why should hypotheses testable?
How else would you determine the validity of the hypothesis.
Pure substance definition?
A pure substance:cannot be separated into 2 or more substances by physical or mechanical meansis homogeneous, ie, has uniform composition throughout the whole sampleits properties are constant throughout the whole sampleits properties do not depend on how it is prepared or purifiedhas constant chemical composition
What are signs a physical change has occured?
change in the form -in general can be indicated for the physical form. The substance may dissolve or its stage may change. If the change is physical, it should be reversable.
Why must an indicator indicate for one substance only?
An indicator does not need to indicate for only one substance. Depending on the field, sometimes it does and sometimes it does not. If it is a drug test where an artificial drug is similar to a natural substance, then an indicator should test for just the illegal substance. In a mine, a number of valuable chemicals are found together. In that case a broad test can be used. You do not care if the chemical reaction shows if any of the desired chemicals are present. If the test is positive, you want to mine the ore. If it is negative, you will save your money.
Are rubies opaque?
Some rubies are opaque but these are considered to be low in value. A ruby that is high in value should be almost transparent and should have bright coloring.
How can you determine if your salmon is cooked properly?
You can determine if your salmon is cooked properly by checking its internal temperature with a food thermometer. The salmon should reach an internal temperature of 145F (63C) to be considered safe to eat. Additionally, the flesh should be opaque and easily flake with a fork when it is cooked through.
How can you determine the density of a substance?
To determine the density of a substance, you would divide the mass of the substance by its volume. The formula for density is density = mass/volume. Measurements should be taken in units such as grams for mass and cubic centimeters for volume.
How you would determine that the distilleate collected is a pure substance?
Pure Substances Boil at a Constant Temperature while Mixtures do not, To determine if the Distillate is pure the Liquid distillate would be boiled and for example if the substance is water, it should begin boiling at exactly at 100 degrees celcius if it boils below or above that point it is not a pure substance
What is the optical property of a container of undeveloped roll of film?
It should be opaque
When a shadow is formed does the object have to be opaque?
when a shadow is formed there should be an opaque object the picture can be formed on the screen.
Why is the choice of the colorimetric indicator in an acid-base titration important?
The choice of colorimetric indicator in an acid-base titration is crucial because it must change color at the equivalence point, where the moles of acid and base are stoichiometrically equal. The indicator should have a pH range close to the pH at the equivalence point to ensure accurate endpoint detection. Using the right indicator helps to determine the endpoint precisely and enhances the accuracy of the titration results.
What should you do if you swallow the substance?
It depends on the substance.
If the equivalence point of a titration is 5 what range of pH should the indicator be?
An indicator should have a pKa close to the expected pH at the equivalence point. For a titration with an equivalence point at pH 5, an indicator with a pKa in the range of 4 to 6 would be suitable for visual detection of the endpoint.
Where is the indicator relay on the polo classic?
The turn signal indicator relay switch can be found below the dashboard on the drivers side. The signal indicator relay switch should be labeled as such.
What creteria is used for chosing an indicator in acid base titration?
pH range of indicator should be in the rapid pH gradient.
