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.
Answer: 212 g of sodium carbonate must react
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products formed must be equal to the mass of reactants taken.
In order to get the same mass on both sides, the atoms of each element must be balanced on both sides of the chemical equation.
The balanced chemical equation is:
Mass of products = mass of sodium chloride + mass of calcium carbonate = 233 g+ 201 g= 434 g
Mass of reactants= mass of sodium carbonate + mass of calcium chloride =x + 222 g
As the mass of reactants should be equal to mass of products
434 = x + 222 g
x = 212 g
Thus 212 g of sodium carbonate must react with 222 g of calcium chloride to make 233 grams of sodium chloride and 201 grams of calcium carbonate
Answer:
The explanation for Constructive and Destructive processes
Explanation:
Collection and analysis of data indicates that constructive forces include crustal deformation, faulting, volcanic eruption and deposition of sediment, while destructive forces include weathering and erosion. I can explain how constructive and destructive forces affect the nature of landforms on Earth.
Explanation:
The radial distribution function gives the probability density for an electron to be found anywhere on the surface of a sphere located a distance r from the proton. Since the area of a spherical surface is 4πr2, the radial distribution function is given by 4πr2R(r)∗R(r).
