D) Volume of gas
E) Temperature

ik ur but stink but get over it

D) Volume of gas

E) Temperature

Explanation:

A balanced chemical equation can provide the following information :

The reactants and products through their symbols and formulae. The ratio of molecules of reactants and products. As molecular masses are expressed in unified mass (u), the relative masses of reactants and products are known from the equation.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.

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.
