What color does phenol red change to when carbon dioxide is present?
It turns a yellow-ish color when CO2 is added.
What happened to the sexual fish once new minnows were added to the pool?
Cells
Is there a whole house air purifier system, or do I need a separate unit in each room?
You can have an air purification system added to your current heating and or cooling system.
Why do substance s expand when energy is added to them as heat?
When heat is added to a system, it increases the kinetic energy of the molecules. Increased K.E in system causes molecules to move further away from each other. This causes system to increase in volume. Significant increase in volume might not occur but at microscopic level it definitely changes.
How does a can of paint get its color?
Pigments are added to the paint. Pigments are added to the paint. Pigments are added to the paint.
What happens when water is added to phenol?
tribromophenol is formed.
What happens when bromine water is added to phenol?
tribromophenol is formed.
Phenol red turns what color when carbon dioxide is added?
Yellow
What element is the donor impurity in silicon?
Silicon has 4 valence electrons. When a penta-valent impurity like phosphorus is added, conduction takes place through the excess electron, the donor. Arsenic is another good example of a donor impurity
What is the nature of bonds in N type and P type semi conductors?
The bonds in a N type or a P type semiconductor depends upon the impurity added into it. For example a trivalent impurity is added then three bonds will be formed by each atom and it becomes a P-type semiconductor whereas if a pentavalent impurity is added then five bonds will be formed by each and every atom and it becomes a N-type semiconductor.
What is doping in conductor?
The process of adding suitable impurities in the intrinsic semiconductor is called doping. The impurity added to the intrinsic semiconductor to increase its conductivity is called dopant. There are some methods of doping in case of a conductor.impurity atoms can be added to the intrinsic semiconductor in different ways discussed below:A very small quantity of impurity atoms is made by diffusing into the high purity molten material such as germanium when the crystal is grown out of melt.Impurity atoms can also be added into the intrinsic semiconductor by heating it in the environment having impurity atoms.Impurity atoms can also be added into the intrinsic semiconductor by bombarding it with the impurity atoms.
Is there a difference in boiling point in water and sulphur water?
Any added impurity can change the boiling point of a liquid.
What color does phenol red change to when carbon dioxide is present?
It turns a yellow-ish color when CO2 is added.
What is carbolic soap?
Soap to which the substance "phenol", also known as carbolic acid, has been added. It is a strong antiseptic.
Why does phenol red and calcium chloride heat up?
I'm not completely sure, but it does have something to do with the water. When added to water the calcium chloride also heats up, so it's not about the phenol, but about the water and the reaction of the reactant dissolving that causes heat.
Diffrentiate n-type and p-type?
When pentavalent impurity is added to pure semiconductor, it is known as N-Type semiconductor. In N-type semiconductor electrons are majority carriers where as holes are minority carriers. impurities such as Arsenic, antimony are added. When trivalent impurity is added to pure semiconductor, it is know as P-type semiconductor. In P-type semiconductor holes are majority carriers whereas electrons are minority carriers. Impurities such as indium, galium are added.
Why the indicator is not used when V ml of acid is added to potassium hydroxide to produce crystal?
When acid is added to base, salts are formed as crystals. If indicator is added, then the indicator may also crystallize which acts as an impurity when compared to the crystals of the salt.
