Cadmium sulphide (CdS) has been used since before bulk silicon was available. Besides Silicon is used as a semiconductor for making electronic transistors. Resistors have to be put on it. Cadmium Sulfide is cheap and works fine.

Can you kill the tree with the help of copper sulphate?

It is not recommended to use copper sulphate to kill a tree, as it can have negative effects on the environment and surrounding plants. Instead, it is advisable to consult with a professional arborist to discuss safe and effective ways to remove a tree if necessary.


Why mohr's salt is used instead of ferrous sulphate in redox titration?

Mohr's salt (ammonium iron(II) sulfate hexahydrate) is used instead of ferrous sulfate in redox titrations because it is more stable and less prone to oxidation by air compared to ferrous sulfate. This helps in achieving more accurate and reliable results in redox titrations.


What is the condensed electron configuration of cadmium?

Cadmium has an electron configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10, commonly written in the shorthand as [Kr] 5s2 4d10. For students who have not learnt spdf notation, the configuration is normally written as 2, 8, 18, 18, 2. It has two valence electrons. The ion would have 8 instead of 10 as the last number.


What other else substances that can use instead of copper oxide in preparing copper sulphate?

Copper carbonate or copper hydroxide can be used as alternatives to copper oxide in preparing copper sulfate. These compounds can react with sulfuric acid to produce copper sulfate in a similar manner to copper oxide.


Why crystals of copper sulphate turn white on heating?

When crystals of copper sulfate are heated, the water of hydration within the crystals is driven off, and the anhydrous copper sulfate formed is white in color. This change in color is due to the removal of water molecules, which alters the crystal structure of the compound and causes it to appear white instead of blue.

Why is colour of copper sulphate blue?

The colour of Copper sulphate is blue because Copper ions absorb light in all frequencies except blue which is reflected instead.


Do copper sulphate crystals have cleavage planes?

No, copper sulphate crystals do not have cleavage planes because they are not considered minerals with cleavage. Cleavage is the tendency of a mineral to break along specific planes due to its crystal structure, which copper sulphate does not exhibit. Instead, copper sulphate crystals tend to break irregularly along their structure.

Do you use a comma to separate a dependent clause and a verb?

Yes, you should use a comma to separate a dependent clause and a verb.


Why are your blood cells red?

Your Blood cells contain Iron which is red there is a animal that uses copper sulphate instead of iron so that's why its blood is blue!


Why transformer is only used instead of any other device?

A transformer is the primary device which transforms voltage to a higher or lower voltage. In electronics, capacitors and resistors perform this function.


Is it harmful to use formocresol for root canal treatment?

It is generally not being used in the UK anymore certainly due to his carcinogenic properties. Ferric sulphate is now used instead.


Why are fixed resistors values indicated by colors?

Because the actual resistor is too small to print numbers, so color bands and math are used instead. I just don't know how to calculate the values.

Blower motor rsistor is hot what is causing this?

The resistors are there to give the blower different speeds. To get the blower to run a little slower part of the energy gets dumped into heating the resistor instead of spinning the blower blades.


What else can be used instead of silicon in the manufacturing of a solar cell?
