Aluminum, silicon, and oxygen form minerals known as aluminosilicates. How many moles of aluminum are in 0.900 moles of pyrophyl
wlad13 [49]

Answer:

There are 1.8 moles of aluminum.

Explanation:

To solve this problem we need to convert moles of pyrophillite (Al₂Si₄O₁₀(OH)) into moles of aluminum (Al):

  • In one mol of Al₂Si₄O₁₀(OH) there are two moles of Al.

With the above information in mind we can now <u>do the conversion</u>:

  • 0.900 moles Al₂Si₄O₁₀(OH) * \frac{2molAl}{1molAl_2Si_4O_{10}(OH)}= 1.8 mol Al

Thus the answer is that there are 1.8 moles of aluminum.

3. A light bulb containing argon gas is switched on,
Readme [11.4K]

Answer:

The assumption is quite reasonable.........

A lightbulb contains Ar gas at a temperature of 295K and at a pressure of 75kPa. The light bulb is switched on, and after 30 minutes its temperature is 418 K. What is a numerical setup for calculating the pressure of the gas inside the light bulb at 418K?

Explanation:
