Well, torr and Hg are different units, but they have the same conversiton with atm.
The conversion for atm to torr or mmHg is 1 atm = 760 torr = 760 mmHg.
Because you have 6.75 atm you can find both the torr and mmHg.
To use dimensional analysis just make sure that you cancel out your units as you go.
6.75 atm * (760 torr / 1 atm) = 5130 torr or 5.13 x 10 to the -3 torr with significant figures.
I hope this helped.
<span>Steel is a solid at standard temperature and pressure conditions. For a solid, the particles are found to be oscillating about a fixed point. However, steel is a metal so this holds true for the positively charged nuclei of the particles. Just like any other metal, the electrons are free to move about, allowing steel to exhibit its properties such as heat conduction and electricity conduction. The reason the positive particles are fixed in place is because the intermolecular forces are very strong in solids, the strongest out solids, liquids and gases.</span>
It is a solution, because it's the alloy of tin and copper
It's a Single Replacement (or Displacement) Reaction because the equation follows the basic format for that type of reaction.
For Single Replacement Reactions, the general formula is:
AB + C = AC + B
So, if there's an element and compound on both sides of the equation, it's single replacement.
Mass percentage = (mass of Al)/(Total mass) * 100
= (26.98) / (26.98 + 3 * (1.0079 + 16)) * 100
= 34.59%
