List the following compounds in decreasing electronegativity difference.

nikdorinn [45]

Answer:

Based on Pauling Scale, electro negativity of Cl = 3.2, Na = 0.9 and H = 2.1

Explanation:

Thus, Electronegativity difference in Cl2 = 3.2 -3.2 = 0

Electronegativity difference in NaCl = 3.2-0.9 = 2.3

Similarly, Electronegativity difference in HCl = 3.2 - 2.1 = 1.1

Thus, among the listed molecules following is the decreasing order of electronegativity difference: NaCl> HCl > Cl2

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.

You want to subtract your cost of 250 in cell e6, from your selling price of 400 in cell e5, and have the result in cell e7. How

Ber [7]

In order to have the result of the above calculation in Cell E7, you need to use the formula<u>, "=E6 - E5."</u>

<h3>Features of Excel</h3>

Allows for calculations from basic math to complex finance.
For subtraction, can simply use the minus (-) to deduct the figure in a cell from another cell.

To subtract the 250 in E6 from the selling price in E5, put an equal sign in E7 and select E5, put a minus (-) sign and then select E6. Press enter.

To extend this to other products, drag the part highlighted in the attachment across to the other products.

In conclusion, Excel can be quite helpful.

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
