Answer : Option D) CO_{3}.

Explanation : A delocalized π bond are those π bonds in which the electrons are allowed to move freely over more than two nuclei. So, amongst the given molecules CO_{3} is the correct answer. As CO_{3} is a molecule which shares a π bond between one carbon and three oxygen atom. The electrons move freely over the whole molecule.

You should remember that a pi bond is related to an alkene, compounds that have a double bond. Among the choices, the only compound that has a double bond is the CO3^2-. Since it is an ion, the pi electrons are delocalized, meaning, their location cannot be indicated as they rotate around the molecules. This is a result of following the octet rule.

a sample of 25.0g of an unknown metal is added to 25.0ml of water in a graduated cylinder and the final volume is 28.5ml what is
leva [86]

Answer:

<h2>The answer is 7.14 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}  \\

From the question

mass of metal = 25 g

volume = final volume of water - initial volume of water

volume = 28.5 - 25 = 3.5 mL

It's density is

density =  \frac{25}{3.5}  \\  = 7.142857...

We have the final answer as

<h3>7.14 g/mL</h3>

Hope this helps you
