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.

the answer is: they rebelled against saddam hussein’s rule.

kurds opposed saddam rule and wanted independence. kurds in the north and shiites in the south revolt against hussein.

for example, the halabja attack in 1988 conducted against the kurdish people by the iraqi regime under saddam hussein, where between 4000 people are killed and around 9000 are injured.

the correct answer to this question is 2
