Determine the number of moles and the mass required for each reaction in exercise 4.44
repeat exercise 4.44
write the balanced equation, then outline the steps necessary determine the information equation in each of the following:
(a)the number of moles and the mass of mg required to react with 5.00g of hcl and produce mgcl2 and h2.
(b)the number of moles and the mass of oxygen formed b decomposition of 1.252 g of silver(i) oxide.
(c)the number of moles and the mass of magnesium carbonate, mgco3, required to produce 283 g of carbon dioxide.(mgo is the other product.)
(d) the number of moles and the mass of water formed b combustion of 20.0 kg of acetylene, c2h2, in an excess of oxygen.
(e) the number of moles and mass of berium peroxide, bao2 neede to produce 2.500 kg of barium oxide, bao (o2 is the other product)

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 for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
