Answer:

317.7778 g

Explanation:

Given data:

Flour required for 18 cup cakes = 260 g

Flour required for 22 cup cakes = ?

Solution:

We will calculate the flour required for 1 cup cake.

260 g /18   = 14.4444 g

Fluor required for 22 cupcakes,

22× 14.4444 g = 317.7778 g

In short,

22 cupcake/18 cup cake×260 g = 317.7778 g

Why do we learn about Laws and Motion ​
Tomtit [17]

So you don't jump off a cliff thinking you could fly. Laws and Motion are heavily used in jobs and help us understand more about the mechanics of how earth's gravity operates. Imagine in the future where we could manipulate gravity? That's why we learn and study this so much.

What mass of AI2O3 forms, knowing the molar mass of Al2O3 is 102 g/mol ?
TiliK225 [7]

Question

What mass of Al₂O₃ form is produced if 25.00 g of aluminum (al) is reacted completely?, knowing the molar mass of Al₂O₃ is 102 g/mol?

Atomic mass of Al =27 and O = 16

The molar mass of Al₂O₃ = 102.

Mass of aluminium in 102 g of Al₂O₃ = 54 g

54 g Al => 102 g Al₂O₃

25g Al => x g Al₂O₃

x = 25*102/54 = 47.2 g Al₂O₃

Seven carbon chain with CH3 attached to second and third carbon
Nikitich [7]

Answer:

2,3-dimethylheptane.

CH₃ - CH - CH-CH₂-CH₂-CH₂-CH₂

           |        |

       CH₃    CH₃

Explanation:

Hello there!

In this case, according to the given instructions, it is possible to draw the organic chemical structure by connecting seven carbon atoms along the parent chain with two methyl substituents at the second and third carbon atoms; thus, the resulting structure is:

CH₃ - CH - CH-CH₂-CH₂-CH₂-CH₂

           |        |

       CH₃    CH₃

Furthermore, the name would be 2,3-dimethylheptane according to the IUPAC rules for nomenclature.

Best regards!

Two reactions and their equilibrium constants are given. A + 2 B − ⇀ ↽ − 2 C K 1 = 2.79 2 C − ⇀ ↽ − D K 2 = 0.186 Calculate the
vfiekz [6]

Answer:

K=1.93

Explanation:

Given reactions are:

A +2B ⇄ 2C  K1=2.79

2C ⇄ D K2=0.186

D⇄ A+ 2B K=?

If we reverse the reaction then the euillibrium constant also become reciprocal of original value:

3rd reaction is a combination of reciprocal of 1st and 2nd reaction

2C⇄A +2B   1/K1;........................1

D ⇄ 2C  1/K2; ..............................2

On adding 1 and 2

D ⇄A +2B    K=\frac{1}{K1} \times\frac{1}{K2};

K=\frac{1}{2.79} \times\frac{1}{0.186};

K=1.93
