Answer:
It should be silicon... I even googled it to see if I was correct and that’s what it says so can someone figure out why silicon is not an answer
Explanation:
Answer:
The answer is forensic sociologist
I just took the exam and it’s rights
Below are the three possible isomers of chemical formula C₂H₂Cl₂. Among these three isomers the <em>trans</em>-1,2-dichloroethene is non-polar while, remaining two are polar.
Reason:
Reason for this is dipole moment. In case of <em>cis</em>-1,2-dichloroethene and 1,1-dichloroethene, the vectors are reinforcing each other perpendicularly to double bond, hence, giving a net dipole moment and making these two isomers polar in nature.
While, in case of <em>trans</em> isomer the two vectors are cancelling each other as the two chlorine atoms are in opposite directions. Hence, the net dipole moment is zero in this case. So, it is non-polar in nature.
when you hit a chemical with hammer and it was frozen only its physical properties will change and not he chemical properties,
when heated it may decompose to other chemical
when you hit with hamer it physical appearance will change but it remains chemically the same
when you put in salt solution , it wil interact with ions and its chemical properties changes
similarly when it was frozen, it retains its chemical properties.
For the reaction to take place the energy of the reactants must reach to the energy level of the products:
we have 900 J in the reactants and 9000 J for the products so the reactants need 8100 J to reach to the value of energy of products (900 + 8100 = 9000)
So the correct answer is C. <span>The reaction absorbs 8100 J of energy from the surroundings as it proceeds. </span>
