X=percentage of Cl-35
(1-x)=percentage of Cl-35
35(x)+37(1-x)=35.454
35x+37-37x=35.454
-2x=35.454-37
-2x=-1.546
x=-1.546/(-2)
x=0.773
0.773=77.3/100=77.3%
(1-x)=1-0.773=0.227
0.227=22.7/100=22.7%
answer: the percentages are: 77.3% of Cl-35 and 22.7% of Cl-37.
Explanation:
here's the answer to your question
Answer:
Single Displacement Reaction: a reaction in which an element is swapped for another in a molecule
A + BC ---> AC + B
Double Displacement Reaction: a reaction in which the cation of one molecule is swapped with a cation of another molecule
AB + CD ---> AD + CB
a) Single Displacement Reaction
3 Ca + 2 AlBr₃ ----> 3 CaBr₂ + 2 Al
b) Single Displacement Reaction
2 Al + 3 MgSO₄ ----> Al₂(SO₄)₃ + 3 Mg
c) Double Displacement Reaction
AgNO₃ + KCl ----> AgCl + KNO₃
When carbon bonds with 4 hydrogen atoms which is methane having sp3 structure so it is tetrahedral. electricity is conducted by electrons so graphite conducts by free and delocalised sea of electrons.
