Saturated oils are oils where every carbon is sp3 hybridized and attached to two other carbons and two hydrogen. An unsaturated oil features a pi bond and a sigma bond between one or more carbons. This sigma bond interacts with Br2 by way of an addition reaction, the double bond is broken and two bromine are added to the carbon chain. The resulting structure is colorless so in a way the oil absorbs the colored Br2 into a colorless molecule. So, the more Saturated an oil is, the more Br2 it can accept and that's why Br2 can be used to detect the presence of satiated oils. While adding Br2, the solution will stay colorless as long as there are double bonds to accept it.

Hope this makes sense, if you've talked about reaction mechanisms this should be pretty straightforward.

Gold has a molar (atomic) mass of 197 g/mol. consider a 2.47 g sample of pure gold vapor. (a) calculate the number of moles of g

adell [148]

N = given mass/ molar mass.
n = number of moles
given mass = 2.47 g
molar mass = 197 g/mol

n = 2.47 / 197
n = 0.01253 moles.
I'm sure you wanted to ask more than this. Just put some comments in. I can do the same.

What effect does a catalyst have on a system in equilibrium?

irina1246 [14]

A catalyst is when a chemical reaction occurs faster than normal.

The system is unaffected during a catalyst because both forward and reverse reactions are affected, meaning that quilibrium will occur faster nothing will change.

Hope it helped,

35.0 mL of 12.0 M HCl is added to enough water to have a final volume of 1.20 L. What is the molarity of the final solution?

creativ13 [48]

<h3>Answer:</h3>

0.35 M

<h3>Explanation:</h3>

<u>We are given;</u>

Initial volume as 35.0 mL or 0.035 L
Initial molarity as 12.0 M
Final volume is 1.20 L

We are required to determine the final molarity of the solution;

Dilution involves adding solvent to a solution to make it more dilute which reduces the concentration and increases the solvent while maintaining solute constant.

Using dilution formula we can determine the final molarity.

M1V1 = M2V2

Rearranging the formula;

M2 = M1V1 ÷ V2

= (12.0 M × 0.035 L) ÷ 1.2 L

= 0.35 M

Thus, the final concentration of the solution is 0.35 M
