Answer:
SO42 - Trigonal planar ion
Explanation:
The SO4^2- ion is tetrahedral and not trigonal planar because the sulphur atom has four regions of electron density which includes the lone pair of electrons on sulphur atom.
This accounts for the observed tetrahedral arrangement of electron pairs around the central sulphur atom in SO4^2- ion, hence the answer.
Answer:
0.13 atm
Explanation:
Using the Ideal Gas Law; PV=nRT, we can rearrange to solve for pressure.
P=nRT/V
P is pressure, n is number of moles (0.023), R is a constant (0.08206 L*atm/mol*K), T is temperature in Kelvin (293.15K) and V is volume, 4.2 L.
So, plugging in;
P=(0.023mol)(0.08206L*atm/mol*K)(293.15K)/(4.2 L)
P=0.1317 atm
P=0.13 atm; multiply by 760 to get to Torr or mmHg.
<h2>The net ionic equation that correspond to Fe(ClO4)2 +Na2CO3 is</h2>
<u>Fe ^2+(aq) +CO3^2-(aq) → FeCO3 (s)</u>
<h3>Explanation</h3><h3 /><h3>write the balance chemical equation</h3>
Fe(ClO4)2 (aq) + Na2CO3(aq)→ FeCO3 (s) + 2 NaClO4
<h3>write the ionic equation</h3>
Fe^2+(aq) + 2ClO4 ^-(aq) + 2Na^+(aq) +CO3^2- (aq) → FeCO3 (s) + 2Na^+ + 2ClO4^-
<h3>cancel the spectator ions in both side</h3>
- that is ( 2ClO4^- and 2Na+)
the ionic equation is therefore
<u>Fe^2+(aq) + CO3^2- →FeCo3(s)</u>
