1. Consider the following thermochemical reaction for kerosene: 2 C12H200 + 37 O260)
24 CO210) + 26 H2O + 15,026 kJ
(a) When 21.3 g of CO2 are made, how much heat is released?
(b) If 500.00 kJ of heat are released by the reaction, how grams of C2H2 must have been consumed ?
(c) If this reaction were being used to generate heat, how many grams of C12H2s would have to be reacted to generate
enough heat to raise the temperature of 750g of liquid water from 10°C to 90°C?

it would be a gas formation

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.
