Answer:
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.
4.) True:
Since
P(E) = 1 - P(Ec)
P(E)+P(Ec)=1
If you think of it as the chances of you getting e or not getting e, then it's a 100% chance of either one happening.
First, we need to transform km to meters.
1 km = 1000 meters
2.6 * 1000 = 2600
Now, there are 7 days in a week.
Multiply.
2600 * 7 = 18,200
Final answer: 18,200 meters a week
