The temperature of a 700. g bar of iron decreases by 30.(C when the iron is plunged into 500. g of water. What is the temperature increase of the water, assuming that no heat is lost in the transfer?

dynamic equilibrium is the answer.

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.

the ratio of the conjugate base to the acid required to attain the desired ph.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
