Convert 6.75 atm to torr Hg (using dimensional analysis method)
Naily [24]
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.

What should we do to reduce the risk when working with concentrated acids and bases
Solnce55 [7]

What should be done to reduce the risk when working with concentrated acids and bases are;

<em><u>1) Ensure that the concentrated acids and bases are stored separately in safety cabinets. </u></em>

<em><u>2) If you don't have separate safety cabinets and the must be stored in same cabinet, then you must ensure that they are stored in separate compartments. </u></em>

<em><u>3) Lastly, the separate compartments or cabinets must have their separate spill containment compounds.</u></em>

          When working with strong acids and bases during neutralization reactions, usually the production of gases can make the solution which is corrosive to splash and get to people around there.

         Due to how strong the acids and base are, these splashes from the neutralized solution could have potentially damaging effects on humans when it contacts them by either casing skin burns or even blindness.  

Now, to reduce the risk of the adverse effects stated above, what could be done is;

1) Ensure that the concentrated acids and bases are stored separately in safety cabinets.

2) If you don't have separate safety cabinets and the must be stored in same cabinet, then you must ensure that they are stored in separate compartments.

3) Lastly, the separate compartments or cabinets must have their separate spill containment compounds.
