Choice 2 possibly, not positive
I believe its the first one because manganese is mn and IV is 4 but the cross thing thing will making it the second one but then you have to simplify making it the first one i hope that helps:)
The axial positions the bond angle is 120 degrees and in equatorial positions the bond angle is 90 degrees.
Functional groups on central atom gets reduce if lone pairs are added.
Explanation:
The number of lone pairs and base pairs of electrons tells the geometry of the molecule.
VSEPR Theory helps to know the lone pairs and bond pair electrons on the centre atom of the molecule.
Example of molecule containing 5 electron pairs can have four bond pairs and 1 lone pair.
eg: Cl
the repulsion is shown as
lp-lp> lp-bp>bp-bp
These are in equatorial position because of the repulsion of lone pairs.
It can have 2 lone pairs and 3 bond pairs. eg. Xe
Lone pairs in this is also in equatorial position as
lp-lp> lp-bp> bp-bp
In axial positions the bond angle is 120 degrees
in equatorial positions the bond angle is 90 degrees, due to the repulsion in lone pair of electrons.
If 1 lone pair is there it can be replaced by bonding with hydrogen.
If 2 lone pairs are there then bonding with oxygen is there. The covalent bond is formed.
Answer:
Lake
Explanation:
Yeah...not much else to say honestly
Lets make x equal the number times you use the 1/5 ratio alloy and y equal the number of times you use the 3/1 ratio alloy. You can make the equation (x+3y)-(5x+y)=0 and (x+3y)+(5x+y)=350
Then you can make the system of equation of:
-4x+2y=0 (this is y=2x)
6x+4y=350
You can make 6x+8x=350 by through substitution and solve of x.
14x=350
x=25 (which means y=50)
that means that the weight of the 1/5 ratio alloy is 150 pounds.
(25+(5x25))=150
the weight of the 3/1 ratio alloy is 200 pounds.
((50x3)+50)=200
I hope this helps.
