Given information:
Central atom = X
# lone pairs on X = 2
# bonds by X = 2 i.e 2 X-Y bonds.
The structure can be represented as Y-:X:-Y
It can be abbreviated as XY2Z2 where Z2 represents the two lone pairs on the central atom X.
Based on the electron geometry which accounts for the 2 two pairs and the 2 bonds, the central atom X would be sp3 hybridized with a tetrahedral geometry
From a molecular geometry perspective (which does not consider the lone pairs), the structure would be linear.
Answer:
Hello everyone and thnx for points
Explanation:
Answer:
It gets squeeze together so tightly that four hydrogen nuclei combine to form one helium atom.
Explanation:
Data:
Arsenic Molar Mass = 74,9216 ≈ 75 u (<span>atomic mass unit)</span>
Solving:
1 mole of arsenic → 75g ------------ 6,02*10²³ molecules
..................................X -------------- 1 molecule
6,02*10²³X = 75
A control sample serves as a sample used to eliminate errors or minimize them. Also, it is used to prevent the effect of one parameter which is not the subject being studied. For instance, in an adsorption experiment a control sample is always included wherein in a flask it only contains the adsorbate solution. The said sample is responsible for calculating how much of the adsorbate is being adsorbed on the sides of the flask.
