Explanation:
Gold and Silver is used for making ornaments because of their <em>malleability</em> and <em>durability</em>. Gold is the most malleable metal. For e.g, a small piece is gold nearly 3.5gm can be made a kilometer thin wire. Gold and and silver are also very <em>lusturous</em> and looks very much <em>lookrative</em>.
Hope this helps
The volume of water vapour gas that would be produced will be 2,581.73 L
<h3>Stoichiometric calculations</h3>
From the equation of the reaction, the mole ratio of propane to oxygen is 1:5.
Mole of 535.55 grams of propane = 535.55/44.1 = 12.12 moles
Mole of 2665.06 grams of oxygen = 2665.06/32 = 83.28 moles
Going by the mole ratio, it appears propane is limiting while oxygen is in excess.
From the equation, 1 mole of propane produces 4 moles of water vapour. Thus, the equivalent mole of water vapour will be:
12.12 x 4 = 48.48 moles.
Using the ideal gas equation: pv = nRt
v = nRT/p = 48.48 x 0.08206 x 623/0.96 = 2,581.73 L

Explanation:
The given data is as follows.
Concentration of acid, [HF] = 2 M
Concentration of salt, [NaF] = 0.472 M
Concentration of base, [NaOH] = 1.00 M
=
So, NaOH being a base will react with the acid that is, HF. And, according to Henderson-Hasselbalch equation we have he following.
pH =
Also, we known that
so,
= 3.1426
Hence, pH =
pH = 2.5155
Thus, we can conclude that pH of the solution is 2.5155.
Answer:
2,2,3- trimethylhexane because it has more carbon atoms than pentane.
Explanation:
Hello.
In this case, since the physical properties of organic compounds are intensified as the number of carbon atoms start increasing on it, the larger the amount of carbon atom, the higher the boiling point since more energy is required to allow the liquid-phase molecules to transcend to the vapor-phase.
In such a way, since pentane has five carbon atoms and 2,2,3- trimethylhexane has nine carbon atoms, 2,2,3- trimethylhexane has the highest boiling point.
Best regards.
