Balance the Following Reaction A coefficient of “1” understand. Choose option “Blank” for the correct answer if the coefficient is “1” C3H8 A(Blank). 2. 6. 7. 4. 5. 3 (Same Numbers answers for the rest of the other question). O2. CO2. H2O

altitude, density, pressure

air gets less dense the higher the altitude and also the air pressure is less as altitude rises.

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.

if it's not useful, feel free to report for mistake in answer.

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
