Do you think that a synthetic Diamond should be treated like a natural Diamond? Why or why not?

Chemistry
1 answer:
grandymaker [24]2 years ago
8 0

No, because a natural diamond is a feat of nature and it is amazing how nature made the intricate structure in a diamond. synthetic diamonds are created in laboratory conditions, so it feels less 'amazing' that the diamond was created because each diamond doesn't feel so unique.

However, the molecular structure of both synthetic and natural diamonds are identical, so it is nearly impossible to tell the difference (if you don't know which is which).

Automotive airbags inflate when a sample of sodium azide, NaN3, is very rapidly decomposed.
Kobotan [32]

Answer:

148 g

Explanation:

Step 1: Write the balanced equation for the decomposition of sodium azide

2 NaN₃ ⇒ 2 Na + 3 N₂

Step 2: Calculate the moles corresponding to 95.8 g of N₂

The molar mass of N₂ is 28.01 g/mol.

95.8 g × 1 mol/28.01 g = 3.42 mol

Step 3: Calculate the moles of NaN₃ needed to form 3.42 moles of N₂

The molar ratio of NaN₃ to N₂ is 2:3. The moles of NaN₃ needed are 2/3 × 3.42 mol = 2.28 mol.

Step 4: Calculate the mass corresponding to 2.28 moles of NaN₃

The molar mass of NaN₃ is 65.01 g/mol.

2.28 mol × 65.01 g/mol = 148 g

220 mL of oxygen gas was collected over water. The total pressure of oxygen plus water vapor was 745.8 mmHg at 25.0°C. What is t
alukav5142 [94]

The pressure, in mmHg, exerted by only the oxygen gas is 720.8 mmHg

<h3>Pressure of gas collected over water</h3>

The total pressure of a gas collected over water is given by P = P' + p where

  • P = pressure of oxygen gas and
  • p = vapour pressure of water at 25 °C = 25 mmHg

Making P' subject of the formula, we have

P' = P - p

Since the total pressure of oxygen plus water vapor is P = 745.8 mmHg, substituting the values of the variables into the equation, we have

P' = P - p

P' = 745.8 mmHg - 25 mmHg

P' = 720.8 mmHg

So, the pressure, in mmHg, exerted by only the oxygen gas is 720.8 mmHg
