Answer:

It's 23.14 percent

Explanation:

First, the mass of all the elements are:

N = 14

O = 16

Fe = 56

In this molecule you have 3 atoms of N, and 9 atoms of O, so:

3•14 = 42

16•9 = 144

The whole mass of the molecule is:

56 + 42 + 144 = 242

242/100 = 2.42, so 1% is 2.42

56/2.42 = 23.14%

How many molecules of CH4 are in 48.2 g of this compound? A) 2.00 x 1023 B) 5.00 x 10-24 C)1.81 x 1024 D) 4.00 E) 4.64 x 1026 10

Tasya [4]

Answer: The correct answer is Option C.

Explanation:

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

Given mass of methane = 48.2 g

Molar mass of methane = 16 g/mol

Putting values in above equation, we get:

$\text{Moles of }CH_4=\frac{48.2g}{16g/mol}=3.0125mol$

According to mole concept:

1 mole of compound contains $6.022\times 10^{23}$ number of molecules.

So, 3.0125 moles of methane will contain = $3.0125\times 6.022\times 10^{23}18.141\times 10^{23}=1.81\times 10^{24}$ number of molecules.

Hence, the correct answer is Option C.

Butadiene c4h6 reacts with itself at 250 degrees celcius to form a dimer with the formula c8h12. The reaction is second order in

goldfiish [28.3K]

Answer:

Rate = k * [C₄H₆]²

Explanation:

It is possible to write the reaction as:

2C₄H₆ → C₈H₁₂

The differential rate law for a simple second order reaction of the type 2A → B is:

Rate = k * [A]²

With the above information in mind, the rate law for the reaction of butadiene would be:

Rate = k * [C₄H₆]²

The molecular structure of water has an asymmetrical arrangement of hydrogen atoms causing.

Sergio [31]

Answer:

the asymmetrical arrangement of hydrogen atoms in a molecule of water causes the molecule to be polar, with the hydrogen atoms having a slightly positive charge, and the oxygen atom having a slightly negative charge.

Sequence the following types of waves from lowest frequency to highest frequency: ultraviolet rays, infrared rays, gamma rays, r

7nadin3 [17]

Light Spectrum:

Gamma Rays; X- Rays; Ultraviolet Rays; Infrared; Micro; Radio

I'm guessing green means the color wave
So it should be: Radio-Infrared- Green - UV - Gamma
This is because frequency decreases when going from left to right on the Light Spectrum!
