How do you explain sugar is not ionizable but it dissolves the water?
Sugar is an organic compound, it contains covalent bonds. Things such as salt (NaCl) form ionic bonds, so they can dissociate in water as ions (Na+ Cl-). The solubility of organic compounds have to do with their polarity. Sugar is polar so it will dissolve in a polar solvent such as water. (like dissolves like)
How does the number of valence electrons in atoms of metalloids explain why metalloids are semiconductors?
Metalloids when used is electronics are called semiconductors.
Why - Neither solid sodium chloride nor liquid water are electrical conductors However when sodium chloride dissolves in water it forms a conducting solution-Explain?
When sodium chloride dissolves in water, it dissolves to form the chloride and sodium ions, therefore forming a conducting solution.
How did Dalton explain the diffrences between a mixture and a compound?
This was not a problem of Dalton.
Can you explain what halogenation is?
The process of halogenation is a chemical reaction between a compound, usually an organic compound and a halogen. An example of halogenation is fluorination or chlorination.
Explain why do copper and iron conduct electricity?
Well metal elements are usually the best conductors of electricity
Solid CaCl2 does not conduct electricity explain why it is considered to be an electrolyte.?
When CaCl2 is placed in water, CaCl2 dissociates, Ca+ and Cl- and ions conduct electricty.
Ethene dissolves in con H2SO4 ethane does not explain?
Ethene is an unsaturated compound so adds up one molecule of sulphuric acid and addition product becomes dissolved in acid but ethane is a saturated compound so does not react and dissolves in sulphuric acid.
Why the diode called polarity switch explain?
A diode will only conduct electricity if the polarity of the current is in the correct direction, because diodes can only conduct in one direction.
Ion which means wanderer to explain why solutions of electrolytes will conduct an electric current When an electrolyte forms into a solution it dissolves or dissociates into ions a process called?
Hydrolysis
Explain why graphite conduct electricity but silicon carbide does not?
Because graphite has one free electron that is not involved in bonding. The one delocalized electron can be used to conduct electricity. However silicon carbide is tetrahedrally bonded to 4 carbon atoms. There is not free electrons in the arrangement. With no delocalized electron, silicon carbide is unable to conduct electricity.
Explain electrical conductivity?
Electrical Conductivity- is the ability of a material to conduct electricity. ( in other words, it tells you what conducts electricity with what.) - your welcome,signed, really smart girl
Explain why a substance needs to be either in a solution or molten for electrolysis to work?
Because electrolysis needs a liquid to conduct the electricity.
Explain why soluble starch does not conduct electricity?
Starch is an chain of sugar molecules, and the chain separates to its individual sugars when dissolved. Because sugars are made of C, H, and O, there are no metals and no ionic bonds in the molecule, so it does not conduct electricity when dissolved in water.
A charge insulater can be discharge by passin it just above a flame explain?
Flame consists in a great portion of ionised gases which conduct electricity.
Explain why one allotrope can conduct electricity?
In one allotrope electrons remain free as charge conductors. In another they may be involved in bonding atoms.
Which part of metallic bonding theory helps the most to explain why metals are able to conduct electricity?
Electrons can move freely among all the atoms of the metal.
