Answer:
Explanation:
Ba( OH)₂ + 2HCl = BaCl₂ + 2H₂O .
75.5 mL of 0.247 M barium hydroxide = .0755 x .247 = .01864 moles
95.0 mL of 0.330 M HCl = .095 x .33 = .03135 moles
mole ratio of hydrochloric acid to barium hydroxide
= .03135 / .01864 = 1.68
theoretical ratio = 2 /1 = 2
As the theoretical ratio is more , therefore HCl is the limiting reactant .
<span>subshells have two reasons of stability-
</span><span> 1) half filled and full filled subshells lead to symmetry as symmetry always increases stability in the nature.
</span>2)<span> in half filled and full filled subshells there are maximum no Of exchanges so exchanges releases energy so it increase stability.. Exchange of e-s also can b understood as delocalization of e-s which is similar like resonance and resonance always increases stability</span>

Answer : The correct option is, (A) 7-chloro-3-ethyl-4-methyl-3-heptene
Explanation :
The rules for naming of alkene are :
First select the longest possible carbon chain.
The longest possible carbon chain should include the carbons of double bonds.
The naming of alkene by adding the suffix -ene.
The numbering is done in such a way that first carbon of double bond gets the lowest number.
The carbon atoms of the double bond get the preference over the other substituents present in the parent chain.
If two or more similar alkyl groups are present in a compound, the words di-, tri-, tetra- and so on are used to specify the number of times of the alkyl groups in the chain.
The given compound name will be, 7-chloro-3-ethyl-4-methyl-3-heptene.
The structure of given compound is shown below.
The violet light has the shortest wavelength.
The sun heats up the air at different rates. Weather is caused by uneven heating
