What is the oxidation number for s in s2o4?

Chemistry
1 answer:
hoa [83]4 years ago
3 0
The oxidation number of O is -2 and there's 4 of them so the total is -8. Since it's a molecule the sum of the oxidation numbers of the atoms must equal 0. If 4 oxygen atoms have an oxidation number of -8 then the two S atoms must is +8 to equal 0 so the oxidation number of the S is 8/2 = +4

A gas is contained in a thick-walled balloon. When the pressure change from 100 kPa to 90.0 kPa, the volume changes from 2.50 L
Orlov [11]
The  temperature  change is   calculated using the  combined  gas law
that  is P1V1/T1  =P2V2/T2
P1=  100KPa
P2=90kpa
v1= 2.50 L
v2= 3.75 L
T1= 303 K
T2=?

T2  is  therefore  =  P2V2T1/P1V1
=( 90  x 3.75  x303)/  (100  x2.50) =  409.05  K

Which of the following molecules or ions is polar? (20 POINTS)
taurus [48]

<u>For NO3- molecule(fig.1)</u>

1.  Bonds are created between elements with different electronegativity, most bonds would be polar. Bonds in NO3 are polar.

2. In the geometry of the molecule  bond polarities cancel out each other (since it is a vector) so NO3- ion molecule is non polar

3.   Nitrate (NO3-)ion  geometry would be trigonal planar

<u>For CCl4 molecule(fig.2)</u>

1. Bonds are created between elements with different electronegativity, most bonds would be polar. Bonds in CCl4 are polar.

2. It is a completely symmetrical molecule.

3.Carbon is the centre of CCl4 have four covalent bonds and it has no lone pairs. They are all equidistant the C-Cl bond polarities cancel out. So CCl4 molecule is non polar

<u>For NH3 molecule(fig.3)</u>

1. Bonds are created between elements with different electronegativity, most bonds would be polar. Bonds in NH3 molecule are polar.

2.  it has a pyramidal structure.

3. the individual N-H bond dipoles don't cancel out. This dipole moment for the molecule indicates that NH3 is a polar molecule

<u>For SF6 molecule(fig.4)</u>

1.F is more electronegative than S. So the bonds are polar.

2. The symmetry of the molecule is  symmetrical so that the dipole moments of bonds cancel correspond so the molecule is non-polar.

3. it has octahedral structure
