2Al+6HCl ->2AlCl3+3H2 .nAl=m/M=13,5/27=0,5(mol) =>nH2=0,5.3/2=0,75(mol)....VH2=n.22,4=0,75.22,4=16,8(lít)...
Answer:
Explanation:
Hello,
By assuming STP conditions (0°C and 1atm), we first compute the reacting moles of both hydrogen and nitrogen as shown below via the ideal gas equation:
Next, one identifies the limiting reagent by computing the moles of hydrogen that completely react with 1.64mol of nitrogen as follows:
In such a way, as there are just 2.65 available moles of hydrogen one states that we have spare nitrogen and the hydrogen is the limiting reagent, thus, the yielded moles of ammonia are computed as:
Finally, one computes the required volume in liters as:
Best regards.
Hey, for #1, it's 1, 1, 1 because it's already balanced!
For #2, it's 1, 2, 1, 1 since the product side has 2 Cl's but left side only had 1.
6. False, Gravity is a force that cannot be changed
7. False, an object with more mass has more/less gravitational force than an object with a smaller mass. Objects that are closer together have more/less of a gravitational force between them than objects that are further apart. The more separation two objects have, the more the force between them decreases.
8. True, objects that are closer together have more/less of a gravitational force between them than objects that are further apart. The more separation two objects have, the more the force between them decreases. When mass 1 increases the force between the objects increases.
9. False, Jupiter, the fifth planet from the Sun, has the strongest gravitational pull because it's the biggest and most massive.
I hope this helps!!
<span>the reason it is important is t</span><span>o verify the results of your experiment with repeated processes that prove them correct.
