The answer is the lake.
A lake is a large expanse of terrestrial water, consisting of streams that are linked to the lake. Although some dimensions of some salt-water lakes are considered island seas; they are therefore distinct from the lagoons, and are larger and deeper than the ponds, while remaining a water body by definition.
Answer: THREE<span> different isomers can be derived from ethylene if two hydrogen atoms are replaced by a fl uorine atom and a chlorine atom.
Explanation: When two Hydrogen atoms in ethylene (
C</span>
₂H₄) are replaced with Fluorine and Chlorine atom then the new molecular formula is
C₂H₂FCl.
Compounds having same Molecular formula but different structural formula are called as Isomers.
First Isomer of C₂H₂FCl is
1-chloro-1-fluoroethene, in which F and Cl at geminal position (attached to same Carbon atom).
Other two Isomers are
Geometrical Isomers of
1-chloro-2-fluoroethene, in which F and Cl at different carbon atom and having different position is space. The one in which both F and Cl at opposite side forms
(<em>
trans</em>
)-1-chloro-2-fluoroethene and the one in which both are in same side is called as
(<em>
cis</em>
)-1-chloro-2-fluoroethene.
The volume of the granite piece in Cm³ is 12.2 cm³
<u><em>calculation</em></u>
volume of granite = (volume of cylinder after placing granite - volume of cylinder before placing granite
= 37.2 ml - 25.0 ml = 12.2 ml
convert ml to Cm³
that is 1 ml = 1 cm³
12.2 ml = ? cm³
<em>by cross multiplication</em>
=(12.2 ml x 1 cm³) / 1 ml = 12.2 cm³
