What maximum amount of ammonia in kilograms can be synthesized from 5.22 kg of h2 and 31.5 kg of n2?

Fiesta28 [93]

Consider the unbalanced reaction,

H₂ + N₂ ===> NH₃

Balance it to get

3 H₂ + N₂ ===> 2 NH₃

This tells you that for every 3 moles of H₂ and 1 mole of N₂ among the reactants, 2 moles of NH₃ are produced.

Look up the molar masses of each component element:

• H : 1.008 g/mol ===> H₂ : 2.016 g/mol

• N : 14.007 g/mol ===> N₂ : 28.014 g/mol

• NH₃ : 17.031 g/mol

Convert the given mass to moles for each reactant:

• H₂ :

(5.22 kg) × (1000 g/kg) × (1/2.016 mol/g) ≈ 2589.29 mol

• N₂ :

(31.5 kg) × (1000 g/kg) × (1/28.014 mol/g) ≈ 1124.44 mol

Now,

(2589.29 mol H₂) : (1124.44 mol N₂) ≈ (2.30 mol H₂) : (1 mol N₂)

so that the amount of N₂ consumed is

(2589.29 mol H₂) × (1 mol N₂) / (3 mol H₂) ≈ 863.095 mol N₂

leaving an excess of about 261.343 mol N₂, and producing

(2589.29 mol H₂) × (2 mol NH₃) / (3 mol H₂) ≈ 1726.19 mol NH₃

Convert this to a mass :

(1726.19 mol) × (17.031 g/mol) × (1/1000 kg/g) ≈ 29.3987 kg

So, up to 29.4 kg of NH₃ can be synthesized.

gulaghasi [49]

Answer:

(a) 31 , 54

(b) 48

Explanation:

Data set : 13 13 13 20 26 29 31 33 34 34 35 35 36 37 38 41 41 41 45 45 47 47 48 52 54 56 56 62 67 82
Part a requires you to find second decile and 8th decile
For second decile there are 30 elements for second decile:

(a) Locator: 0.2*30 = 6

Round up to 7

20% decile = 31

For 8th decile

Locator: 0.8*30 = 24

Round up to 25

80% decile = 54

(b) To determine 67th percentile

Locator : 0.67^30 = 20.1

Round up to 22

67% percentile = 48

Triangle PQR has right angle Q. If sin R = 4/5<br> what is the value of tan P?

icang [17]

By applying Pythagorean' theorem, the value of tanP is equal to 3/4.

<h3>How to determine the value of tan P?</h3>

Since triangle PQR has right-angle Q and sinR = 4/5, we have:

sinR = Opp/hyp = 4/5

tanP = Opp/Adj = QR/4

Next, we would determine the length of QR by applying Pythagorean' theorem:

PR² = QR² + PQ²

5² = QR² + 4²

25 = QR² + 16

QR² = 25 - 18

QR = √9

QR = 3 units.

For the value of tanP, we have:

tanP = 3/4.

At stp, fluorine is a gas and bromine is a liquid because, compared to fluorine, bromine has.

vovangra [49]

Bromine has stronger inter molecular force than Fluorine.

<h3> Inter molecular forces and relationship with physical states of matter</h3>

The intermolecular forces of a substance tells the physical state of that substance , We can therefore say that the Solid, liquid and gas states of substances depends on the intermolecular forces surrounding them.

For solids,the inte molecular forces will be so strong as they draw the molecules together giving them a compact structure.

For liquids, the the inter molecular forces will be just strong enough to keep the molecules together in a confined space.

For gases, the the inter molecular forces are weakest as the molecules move about.

We can then conclude that At stp, fluorine is a gas and bromine is a liquid because, compared to fluorine, bromine has a stronger intermoleclar force.
