Write a balanced chemical equation based on the following description: hydrogen chloride gas reacts with solid silicon to produce trichlorosilane
gas and hydrogen gas

explanation:

i think option no d is the correct answer

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
