if kept at a constant temperature, what is the concentration at 865s if the initial concentration was 0.0225M

Anestetic [448]

Answer:

$[SO_2Cl_2]=0.0175M$

Explanation:

Hello!

In this case, considering that the decomposition reaction of SO2Cl2 is first-order, we can write the rate law shown below:

$r=-k[SO_2Cl_2]$

We also consider that the integrated rate law has been already reported as:

$[SO_2Cl_2]=[SO_2Cl_2]_0exp(-kt)$

Thus, by plugging in the initial concentration, rate constant and elapsed time we obtain:

$[SO_2Cl_2]=0.0225Mexp(-2.90x10^{-4}s^{-1}*865s)$

$[SO_2Cl_2]=0.0175M$

Best regards!

If an element is lustrous, brittle, and a semi-conductor, how would you classify it?

just olya [345]

Metalloid

Explanation:

If an element is lustrous, brittle and a semi-conductor, it is best classified as a metalloid.

Metalloids shares attributes of metals and non-metals.

They are often described as semi-metals as they do not share the full properties that makes a metal a metal.
Metalloids are lustrous but not malleable like metals.
They do not conduct electricity but they do so on certain conditions.
Examples are silicon, germanium, boron, arsenic e.t.c
They are usually found in the middle of the periodic table.
They are not readily alloyed with metals.

Give the molecular geometry and number of electron groups for sf4. give the molecular geometry and number of electron groups for

Andrei [34K]

Answer:

5 electron groups, see saw

Explanation:

During the formation of SF4, the sulfur atom usually bonds with each of four fluorine atoms where 8 of valence electrons are used. The four fluorine atoms have 3 lone pairs of electrons in its octet which will further utilize 24 valence electrons. In addition, two electrons are present as a lone pair on the sulfur atom. We can determine sulfur’s hybridization state by counting of the number of regions of electron density on sulphur (the central atom in the molecule). When bonding takes place there is a formation of 4 single bonds to sulfur and it has 1 lone pair. Looking at this, we can say that the number of regions of electron density is 5. The hybridization state is sp3d.

SF4 molecular geometry is seesaw with one pair of valence electrons. The molecule is polar. The equatorial fluorine atoms have 102° bond angles instead of the actual 120° angle. The axial fluorine atom angle is 173° instead of the actual 180° bond angle.
