Draw the structural formula of (3e,5e)-2,5-dibromo-3,5-octadiene.
mrs_skeptik [129]

We need draw the structure of (3E,5E)-2,5-dibromo-3,5-octadiene.

The structure is shown below:

The molecule has two double bonds in 3 and 5 position and two Br-atoms attached to 2 and 5 position.

The configuration is 3E and 5E. E configuration indicates cis- isomers where similar groups are in same side with respect to double bonds.

3. If you start with 8x1025 molecules of Cl, and 25 grams of KI, how many grams of KCl would
miskamm [114]

Answer:

Percent yield = 89.1%

Explanation:

Based on the equation:

Cl₂ + 2KI → 2KCl + I₂

<em>1 mole of Cl₂ reacts with 2 moles of KI to produce to moles of KCl</em>

<em />

To solve this quesiton we must find the moles of each reactant in order to find the limiting reactant. With the limiting reactant we can find the moles of KCl and the mass:

<em>Moles Cl₂:</em>

8x10²⁵ molecules * (1mol / 6.022x10²³ molecules) = 133 moles

<em>Moles KI -Molar mass: 166.0028g/mol-</em>

25g * (1mol / 166.0028g) = 0.15 moles

Here, clarely, the KI is the limiting reactant

As 2 moles of KI produce 2 moles of KCl, the moles of KCl produced are 0.15 moles. The theoretical mass is:

0.15 moles * (74.5513g / mol) =

11.2g KCl

Percent yield is: Actual yield (10.0g) / Theoretical yield (11.2g) * 100

<h3>Percent yield = 89.1%</h3>

Which of the following liquid substances would you expect to have the lowest surface tension? And why? what intermolecular force
mamaluj [8]

Answer:

CH3OCH3

Explanation:

Surface tension is directly proportional to the strength of the inter molecular bonds. So the one with the weakest intermolecular forces will have the lowest surface tension. Lead has the highest intermolecular forces (metallic bonds), water and alcohol have hydrogen bonding which are the second strongest bonds here. CH3OCH3  and HOCH2CH2OH both have London dispersion forces but CH3OCH3 has weaker ones of the two because it is smaller and therefore has the lowest surface tension
