matter can take be one of the three states which are; (Solid, Liquid, Gas)
Think about water, it can be a Solid (Ice) a Liquid (not frozen obviously) and a Gas (when it evaporates)
Answer:
5727 years or 5730 (rounded to match 3 sig figs) whichever one your teacher prefers
Explanation:
First Order decay has a half life formula of Half Life = Ln (2) / k = 0.693/K
Half-life = 0.693/k = 0.693/1.21 x10-4 = 5727 years or 5730 (rounded to match 3 sig figs)
This should be correct because if you google the half-life of 14 C it is ~ 5700 years
It will slowly rotten and turn brown
Answer : 
is the molecule that exhibit dipole-dipole forces as its strongest intermolecular force.
Explanation : The shape or geometry of given molecules of 
, 
, 
, 
and are linear, linear, tetrahedral, trigonal planar and angular respectively.
The given molecules , , , are symmetrical molecules. These symmetric molecules cannot exists as dipole even they contain polar bonds. Thus, these molecules will not exhibit dipole-dipole forces.
molecule has polar bonds and unsymmetrical bonds as shown in attached image. This molecule cannot exhibit H-bonding. It exhibit only dipole-dipole forces.
Therefore, molecule exhibit dipole-dipole forces as strongest intermolecular force.
They all are made up with something to get their form is how they are all alike. how they are different is on is a solid where is is still an the next is liquid an it is like solid but moves and gas is nothing but like air we breath. hope this helps...
