Difference between Aluminum and Duralumin

1 answer:

4 0

Aluminum is the pure metal element from which the Duralumin alloy is made.

Duralumin contains aluminum and copper. An alloy developed first by a German metallurgist. Dura is actually part of the trade name: dura for durable.

More durable than raw aluminum it is used in airplane frames, laminated with coat of aluminum. Combining strength of the alloy and corrosion resistance of pure aluminum.

What is the [H+] concentration of a solution with a pH of 3.78

lianna [129]

Answer:

[H+] = 1.66 x $10^{-4}$

Explanation:

To find the [H+] concentration of a solution, we can use the formula:

$[H+] = 10^{-pH}$

Let's plug in the pH.

$[H+] = 10^{-3.78}$

Evaluate the exponent.

[H+] = 1.66 x $10^{-4}$

Hope this helps!

When 8.70 kJ of thermal energy is added to 2.50 mol of liquid methanol, it vaporizes. Determine the heat of vaporization in kJ/m

Anni [7]

Answer:

The heat of vaporisation of methanol is "3.48 KJ/Mol"

Explanation:

The amount of heat energy required to convert or transform 1 gram of liquid to vapour is called heat of vaporisation

When 8.7 KJ of heat energy is required to vaporize 2.5 mol of liquid methanol.

Hence, for 1 mol of liquid methanol, amount of heat energy required to evaporate the methanol is = $\frac{8.7}{2.5}KJ$

= 3.48 KJ

So, the heat of vaporization $\delta H_{vap} = 3.48KJ/Mol$

Therefore, the heat of vaporization of methanol is 3.48KJ/Mol

How are monosaccharides and polysaccharides structurally different? *NO PLAGIARISM PLS*

Mariana [72]

Explanation:

Monosaccharides are simple carbohydrates that cannot be further hydrolyzed to simpler carbohydrates. They contain between three and six carbon atoms per molecule.

Polysaccharides are complex carbohydrates . They are condensation polymers derived from very long chains of monosaccharide units.

Structurally, polysaccharides are made up of repeating units of monosaccharides.
