The problem here is incomplete. Luckily, I found a similar problem from another website which is shown in the attached picture. So, the useful information here are the stoichiometric coefficients of the reaction and the initial amount of 7.49 g of S. The solution is as follows:

Molar mass of S = 32.06 g/mol
Molar mass of SO₃ = 80.06 g/mol

Theo yield of SO₃ = (7.49 g S)(1 mol S/32.06 g)(2 mol SO₃/2 mol S)(80.06 g SO₃/mol) = 18.7 g SO₃

Why is the structure of a molecule important to its function

Scilla [17]

Answer:

It determines how biological molecules recognize and respond to one another with specificity.

Explanation:

A molecule has a characteristic size and shape. The precise shape of a molecule is usually very important to its function in the living cell. Molecular shape is crucial in biology because it determines how biological molecules recognize and respond to one another with specificity.

) If you started with 2.3182 g of 3-nitrophthalic acid and had a 93% yield of 3-nitrophthalhydrazide, how many grams of 3-nitrop

MArishka [77]

Answer: 1.8124 g of 3-nitrophthalhydrazide were recovered.

Explanation:

The balanced chemical reaction will be :

$C_8H_5NO_6+N_2H_4\rightarrow C_8H_5N_3O_4+2H_2O$

moles of 3-nitrophthalic acid = $\frac{\text {given mass}}{\text {molar mass}}=\frac{2.3182g}{211.13g/mol}=0.0110mol$

As 1 mole of 3-nitrophthalic acid gives = 1 mole of 3-nitrophthalhydrazide

0.0110 moles of 3-nitrophthalic acid gives = $\frac{1}{1}\times 0.0110=0.0110$ mole of 3-nitrophthalhydrazide

mass of 3-nitrophthalhydrazide = $moles\times {\text {molar mass}}=0.0110mol\times 177.16g/mol=1.9488g$

As the percentage yield is 93% , the mass of 3-nitrophthalhydrazide recovered = $\frac{1.9488\times 93}{100}=1.8124g$

Therefore 1.8124 g of 3-nitrophthalhydrazide were recovered.

Which of the subshells below do not exist due to the constraints upon the angular momentum quantum number?A) 2dB) 2sC) 2pD) all

Gnom [1K]

Answer:

Option A): Due to the constraints upton the angular momentum quantum number, the subshell 2d does not exist.

Explanation:

The angular momentum quantum number, identified with the letter l (lowercase L), number is the second quantum number.

This number identifies the shape of the orbital or kind of subshell.

The possible values of the angular momentum quantum number, l, are constrained by the value of the principal quantum number n: l can take values from 0 to n - 1.

So, you can use this guide:

Principal quantum Angular momentum Shape of the orbital

number, n quantum number, l

1 0 s

2 0, 1 s, p

3 0, 1, 2 s, p, d

Hence,

the subshell 2d (n = 2, l = 2) is not feasible.

2s (option B) is possible: n = 2, l = 0

2p (option C) is possible: n = 2, l = 1

Calculate the volume of 0.684mol of carbon dioxide at s.t.p. show working

solong [7]

Answer: The volume of 0.684 mol of carbon dioxide at s.t.p. is 15.3 L

Explanation:

According to ideal gas equation:

$PV=nRT$

P = pressure of gas = 1 atm (at STP)

V = Volume of gas = ?

n = number of moles = 0.684

R = gas constant = $0.0821Latm/Kmol$

T =temperature = $273K$ (at STP)

$V=\frac{nRT}{P}$

$V=\frac{0.684\times 0.0821L atm/K mol\times 273K}{1atm}$

$V=15.3L$

Thus the volume of 0.684 mol of carbon dioxide at s.t.p. is 15.3 L

Calculate the rcf (recipe conversion factor) for a new yield of 80 oz. (5 lbs) blueberry muffin batter. the original yield of th

SCORPION-xisa [38]

The rcf (recipe conversion factor)= 0.6

<h3>What is the rcf (recipe conversion factor)?</h3>

The conversion factor approach is the most typical technique for modifying recipes.
Finding a conversion factor and multiplying the ingredients in the original recipe by that factor are the only two steps needed to do this.
Remember that the conversion factor will be larger than 1 if you are raising your amounts to be sure you are finding it correctly.
The factor will be less than 1 if your amounts are being decreased. Use the conversion factor approach if you come across a recipe that is written in a standard format.

The production of phenolic monomers from lignin is effective and selective when done using reductive catalytic fractionation (RCF).

How this is calculated?

Conversion Factor = New Yield ÷ Old Yield

=80/134

=0.5970

=0.6(rounded to nearest tenth)
