<span>The 28,0 cmÂł piece of lead has more mass than the 16,0 cmÂł piece of gold. A simple calculation shows that 16X 19,3 grams is 308,8 grams (gold) and 28X 11,4 grams is 319,2 grams.</span>
AICI13 and Ag are the products are formed
The answer is false, I hope this helps.
Using the VSPER theory, the effect of lone pairs on molecular shape can be discussed.
There are 3 types of electron pairs present in a molecular shape: bond pair -bond pair, lone pair - bond pair, lone pair - lone pair.
Strength of repulsions between these three types of pair follows the order:
lone pair- lone pair > lone pair - bond pair > bond pair - bond pair
Whenever there is an addition of lone pairs to the geometry, some distortions take place which decreases the bond angles and some asymmetry is attained in the original molecular shape.
<span>B. The model gradually changed as new scientific data was gathered.</span>
