CH4(9) + 2Cl2(g) → CC14(g) + 2H2(9) = -74.8 kJ/mol
AH & CHA
AHECCIA
= -106.7 kJ/mol
Which of these are true for the reaction above? Check all that apply.
AHxn is -31.9 kJ.
AHxn is - 181.5 kJ.
The reaction is endothermic, +AH.
The reaction is exothermic, -AH.
Heat is a product

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.

explanation:

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.
