We call these reactive elements, becausethese atoms really like to follow the buddysystem and form bonds with other atoms.Noble gases, however, don't have thisproblem. Their outer shells are filled to the max, so they don't need to bond or react with any other atoms.
<span>First of all, an ounce of hard liquor (gin, vodka,
rum, whiskey, or scotch) contains 64 calories for 80 proof varieties,
and 80 calories for those that are100 proof. The proof refers to the
percentage of alcohol in the liquor (80 proof is 40 percent alcohol; 100 proof is 50 percent alcohol)</span>
Answer:
The PH2 becomes attached to the alkyl halide with inversion of configuration
Explanation:
SN2 reaction involves the simultaneous attachment of the nucleophile as the leaving group departs. This leads to an inversion of configuration because the sterochemistry around the carbon bearing the leaving group is reversed. The reaction proceed via a crowded five coordinate transition state. Details are shown in the image attached.
Answer:
An electron will jump to a higher energy level when excited by an external energy gain such as a large heat increase or the presence of an electrical field, or collision with another electron.
Explanation:
hope it helps you
Answer:
2
Explanation:
#1 is incorrect as there is no upward force that would balance the 5 N downward force
#3 is incorrect 2 is less than 5 = net force downward of 3 N
#4 is incorrect 5 is greater than three = 2 N net force going to the left and 2N going up
