Answer:
When substances do not mix thoroughly and evenly (like sand and gravel), the mixture is said to be heterogeneous. A heterogeneous mixture consists of visibly different substances. Another example of a mixture is salt dissolved in water.
Hope it helps!
1) same amount of carbon atoms.
That is why it is still called butane and butene.
but- always signifies 4 carbons
A molecular formula represents the exact number of atoms present for each element in the compound.
For carbon atom: = ( as molar mass of carbon is 12 g/mol)
Now, 6 carbon atoms are present and rest are hydrogen atoms i.e. 6
Thus, formula becomes (
Now, check for unsaturation:
Degree of unsaturation =
Substitute the value of x and y,
Degree of unsaturation =
=
= implies one ring and three double bonds.
Thus, formula comes out to be i.e. benzene ring.
The correct answer is D. Using the law of conservation of mass the number of atoms on each side of the equation should be equal. Through introspection, we find that there are 2 atoms on reactant side as opposed 3Cl atoms on product side. If we add a coefficient of 3 on we get
.
Now there are 6Cl atoms on reactant side and 2 on product side, hence we add a coefficient of 2 on both and . The balanced chemical equation is,
Because as u go across groups the more reactive it is due to the ability of electrons to be given or taken away
