An industrial vat contains 650 grams of solid lead(ii) chloride formed from a reaction of 870 grams of lead(ii) nitrate with excess hydrochloric acid. this is the equation of the reaction: 2hcl + pb(no3)2 → 2hno3 + pbcl2. what is the percent yield of lead(ii) chloride? the percent yield of lead chloride is %.

89%

Explanation:

Should be calculated to two significant figures so i assume its 89%

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 formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)
