False, neutrons are not a classification, acid and base are though
They called it the Tariff of Abomination aka the Tariff of Evil because it really hurt the south. Any tariffs hurt the South with their agricultural business so I guess they believed it would lead to losing their jobs, etc..
Answer: Element is a substance that is made entirely from one type of atom. For example, the element hydrogen is made from atoms containing a single proton and a single electron
Explanation:a b d
If you decrease the pressure of a fixed amount of gas, its volume will increase.
The correct answer to this question is this one:
use PV=nRT
we can convert it into P=(mRT/MV) then P=dRT/M
so at STP:
T= 25 celsius which equals 298.73 Kelvin
<span />d= 1.046 g/mL = 0.001046 g/L (we need to use litres in the ideal gas equation)
<span />R =0.08206 Latm/Kmol
<span />M= molar mass of C16H22O4, which is (12)16+(1)22+(16)4 = 278 g/mol
<span>so plug this into: P=dRT/M
once you found the pressure, P, you need to convert it into torr (because it will be in atm (atmospheres).. since 1 atm = 760 torr = 760 mm Hg
multiply P by 760 and you're done. You;ll have the pressure in torr </span>
