Answer:

Sulfur

Explanation:

In general, elements are more reactive the more electronegative they are. The most electronegative elements are at the top-right of the periodic table. Since sulfur (S) is one unit up and one unit to the right of arsenic (As), it is considered more electronegative, and therefore more reactive, than arsenic.

In a 35.0 L tank of N2O3 at STP, how many molecules are there?

likoan [24]

Answer:

$9.40x10^{23}molecules$

Explanation:

Hello!

In this case, since we are given the volume of N2O3 and pressure and temperature for the STP (1.00 atm and 273.15 K), we can compute the moles, considering the ideal gas equation as shown below:

$PV=nRT\\\\n=\frac{PV}{RT} \\\\n=\frac{1atm*35L}{0.08206\frac{atm*L}{mol*K}*273.15K}\\\\n=1.56mol$
