50.0kg of nitrogen and 10.0kg 0f hydrogen are mixed to produce ammonia . calculate the ammonia formed, identify the limiting rea
Nana76 [90]

Answer:

Nitrogen is limiting reactant and 30.4kg of ammonia can be formed

Explanation:

Nitrogen, N₂, reacts with hydrogen, H₂ to produce ammonia, NH₃, as follows:

2N₂ + 3H₂ → 2NH₃

<em>Where 2 moles nitrogen reacts with 3 moles of hydrogen to produce 2 moles of ammonia</em>

<em />

To solve this question we must find the moles of each reactant in order to find limiting reactant. With limiting reactant we can find the moles and the mass of ammonia formed as follows:

<em>Moles N2 -Molar mass: 28g/mol-</em>

50000g * (1mol / 28g) = 1786 moles N2

<em>Moles H2 -Molar mass: 2g/mol-</em>

10000g * (1mol / 2g) = 5000 moles H2

For a complete reaction of 5000 moles H2 are needed:

5000 mol H2 * (2mol N2 / 3mol H2) = 3333 moles N2. As there are just 1786 moles, Nitrogen is limiting reactant

The moles of ammonia that can be produced are 1786 moles because 2mol N2 = 2moles NH3.

The mass of ammonia -Molar mass NH3: 17g/mol- is:

1786 moles NH3 * (17g / mol) = 30362g =

30.4kg of ammonia can be formed

1. Which of the following should have the highest boiling point?
amm1812

Answer:

1. CBr4

2. C5H12

3. CF4

4. C8H17NH2

Explanation:

1. The boiling point of a molecule depends on its structure. Because the boiling point of molecules of similar size, depends on the differences in functional groups of the molecule.

For example CBr4 have a higher boiling point than other compounds because they have both London dispersion forces and dipole-dipole interactions.

2. Non-polar molecules like C5H12 will have low melting and boiling points, because they are held together by the weak van der Waals forces.

ra1l [238]

Answer:

yes

Explanation:

math is used constantly to improve one's performance. Achieving the objective of shooting a basketball includes using percentages and angles. By finding the most consistent percentage of shots made while using a certain angle, you can find out which player will score the most baskets.

H2SO4 is added to a large beaker of water. How is the solution different from the original water?
asambeis [7]
When concentrated sulfuric acid, H2SO4(l), is added to water it will form a solution containing hydrogen ions and hydrogen sulfate ions. H2SO4 is a strong acid, but only for the first H+. The remaining HSO4^- is a weak acid. Since it forms an acidic solution, it will change blue litmus to red.
