r = radius of ball

r = 12 cm
Volume is :

Answer:
D) will not form any stereoisomers since the product is a saturated hydrocarbon.
Explanation:
Stereoisomerism, or spatial isomerism,refers to a type of isomerism in which two or more molecules have the same molecular formula and atom to atom connectivity but different three-dimensional orientations of those atoms in space.
Stereoisomerism occurs in alkenes because free rotation about the C=C bond is hindered. Thus, the molecule is "locked" in a particular orientation. In a saturated alkane, there is unrestricted free rotation about the C-C bond hence straight chain alkanes do not have steroisomers.
The product formed is 3,4-dimethyl hexane which is a straight chain saturated alkane. This compound does not exhibit stereoisomerism.

Answer:
The equilibrium will change in the direction of the reactants
Explanation:
321.1 g of strontium phosphite will contain 0.76 moles of strontium phosphite in the beaker.
<u>Explanation:</u>
It is known that 1 mole of any substance is equal to the molar mass of that substance. So for the case of strontium phosphite, the molar mass is found to be 420.8 g/mol.
This means 1 mole of Strontium phosphite will contain 420.8 g of strontium phosphite.
Then 1 g of strontium phosphite will have
moles of strontium phosphite.
So, 321.1 g of strontium phosphite will contain 
Thus, 321.1 g of strontium phosphite will contain 0.76 moles of strontium phosphite in the beaker.
