How many grams of NO are required to produce 145 g of N2 in the following reaction?
V125BC [204]

Answer:

b. 186 g

Explanation:

Step 1: Write the balanced equation.

4 NH₃(g) + 6 NO(g) → 5 N₂(g) + 6 H₂O(l)

Step 2: Calculate the moles corresponding to 145 g of N₂

The molar mass of nitrogen is 28.01 g/mol.

145g \times \frac{1mol}{28.01 g} =5.18 mol

Step 3: Calculate the moles of NO required to produce 5.18 moles of N₂

The molar ratio of NO to N₂ is 6:5.

5.18molN_2 \times \frac{6molNO}{5molN_2} = 6.22molNO

Step 4: Calculate the mass corresponding to 6.22 moles of NO

The molar mass of NO is 30.01 g/mol.

6.22mol \times \frac{30.01g}{mol} =186 g

Which compound has a molecular ion at m/z = 58, an infra red absorption at 1650cm^-1?
rewona [7]

CH_{3}COCH_{3} (acetone) has a molecular ion at m/z = 58, an infra red absorption at 1650cm^-1

Acetone is a synthetic substance that is also naturally present in the environment. It is a tasteless, colourless liquid with a distinct odour. It is combustible, readily evaporates, and dissolves in water. It is also known as beta-ketopropane, 2-propanone, and dimethyl ketone. Plastic, fibres, medications, and other compounds are all made from acetone.

Other substances can also be dissolved with it. It is a byproduct of the breakdown of human fat and is found naturally in plants, trees, volcanic gases, forest fires, and other organisms. It can be found in landfills, tobacco smoke, and automobile exhaust. Acetone is released into the environment more through industrial processes than through natural ones.

Explanation:

Given that,

The frequency of electromagnetic spectrum is 2.73\times 10^{16}\ Hz

(A) Let the wavelength of this radiation is \lambda. We know that,

c=f\lambda\\\\\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{2.73\times 10^{16}}\\\\\lambda=1.09\times 10^{-8}\ m

So, the wavelength of this radiation is 1.09\times 10^{-8}\ m.

(B) Let E is the energy associated with this radiation. Energy of an electromagnetic radiation is given by :

E=hf

h is Planck's constant

E=6.63\times 10^{-34}\times 2.73\times 10^{16}\\\\E=1.8\times 10^{-17}\ J

1 kcal = 4184 J

It means,

1.8\times 10^{-17}\ J=\dfrac{1}{4184}\times 1.8\times 10^{-17}\\\\=4.3\times 10^{-21}\ \text{kcal}

Hence, this is the required solution.
