At 1023 K and 1 atm, a 3.00 gram sample of Snoz(s) (gram-formula mass = 151 g/mol) reacts with hydrogen gas to produce tin and water, as
shown in the balanced equation below:
SnO2 (s) + 2H2(g) + Sn(l) + 2H2O(g)
Determine the number
of moles of sn(l)
produced when 4.0
Moles of H2(g) is completely consumed

2 moles of Sn are produced when 4 moles of H2(g) are consumed completely

Explanation:

to determine the number of moles of sn (l) produced when 4.0 moles of H2 (g) is consumed completely.

First, find the number of moles of H2 consumed by taking this as limiting reagent.

Then find the moles of Sn (l) taking into account the stoichiometric relationship between H2(g) and Sn(l). 2:1

                          (s) + 2(g)  ⇒  Sn(l) + 2(g)

∴2 moles of Sn are produced when 4 moles of H2(g) are consumed completely.

explanation:

crosscutting concepts have application across all domains of science. as such, they are a way of linking the different domains of science. they include patterns; cause and effect; scale, proportion, and quantity; systems and system models; energy and matter; structure and function; and stability and change.

the answer is the first option

explanation:

just googled it m8. not that hard
