The two types of data are Qualitative and Quantitative data. Qualitative data is the data that cannot be quantified or measured where as quantitative data is quantified that is measured in terms of numbers.
The given statement 17 birds drink from the pond over the course of 2 hours describes the number of birds that drink water over a given amount time. So, it represents quantitative data. Hence the given statement that The following statement describes qualitative data: 17 birds drink from the pond over the course of 2 hours is false.
Answer:
<u><em>Pasteurization:</em></u>
It is the process in which any beverage such as milk or any other liquid is heated at a certain temperature to kill the bacteria and microorganisms that can cause spoilage or fermentation or any other disease.
Answer:
A conducting electricity
Explanation:
The "electron sea" allows the current to flow across the electrons. If the electrons were stuck in their positions, these metals would be better insulators than conductors because they couldn't spread (or <em>conduct) </em>the energy as electricity.
B, C, and D are all not things directly caused by the delocalized electrons.
Start with the ideal gas equation, <span><span><span>PV=nRT</span> </span><span>PV=nRT</span></span>
and rearrange for pressure to get <span><span><span>p=<span><span>nRT</span>V </span></span> </span><span>p=<span><span>nRT</span>V</span></span></span>
. You have all the necessary variables in their proper units, so plug em' into the equation to solve for pressure in units of atmospheres.
<span><span><span>P=<span><span>(2.5 mol)(300 K)(0.08206 L atm <span><span>K </span><span><span>−1</span> </span></span> mo<span><span>l </span><span><span>−1</span> </span></span></span><span>50.0 L</span> </span>=1.23 atm</span> </span><span>P=<span><span>(2.5 mol)(300 K)(0.08206 L atm <span>K<span>−1</span></span> mo<span>l<span>−1</span></span></span><span>50.0 L</span></span>=1.23 atm</span></span>
All that needs to be done now is converting atmospheres to mm <span><span><span>Hg</span> </span><span>Hg</span></span>
.
<span><span><span>1.23 atm∗<span><span>760 mm Hg</span><span>1 atm</span> </span>=935 mm Hg</span> </span><span>1.23 atm∗<span><span>760 mm Hg</span><span>1 atm</span></span>=935 mm Hg</span></span>
.
That value makes sense, since the original pressure in atmospheres was above 1, the pressure in mm <span><span><span>Hg</span> </span><span>Hg</span></span>
will be above 760.
