Natasha2012 [34]3 years ago
6 0

Unsaturation number (un) or double bond equivalent (dbe) can be calculated as:

=C+1-(H/2)

Where C=number of carbon atoms

H=number of hydrogen atoms

So here the compound is C7H6O3

C=7

H=6

Presence of oxygen will not affect the DBE.

So DBE= 7+1-(6/2)

=5

Solve for y in the following problem: 5.3 x 10- (y)(2y)
weqwewe [10]

Answer:

The value of y = 5.1478

Explanation:

The linear equation is an equation obtained when a linear polynomial is equated to zero. When the solution obtained on solving the equation is substituted in the equation in place of the unknown, the equation gets satisfied.

The given equation: 5.3 x 10- (y)(2y) = 0

⇒ 53 - 2y² = 0

⇒ 2y² = 53

⇒ y² = 53 ÷ 2 = 26.5

⇒ y = √26.5 = 5.1478
