Ionic bonds is formed between a metal and a nonmetal because the metal transfers it's valence electrons to the nonmetal. Electrons doesn't transfer between two nonmetal because both are negatively charged.
I don’t have a picture but I can describe it to you.
The hydrogen that is attached at the tertiary position on the heptatriene (at the 7-methyl) would be very acidic, as removal would leave a positive charge that could be moved throughout the ring through resonance. This would mean that the three double bonds would be participating in resonance, and the deprotonated structure would be aromatic, thus making this favorable.
The hydrogen that is attached at the tertiary position on the pentadiene (5-methyl) would NOT be acidic, as removal would cause an antiaromatic structure.
Any other hydrogens would NOT be acidic. Those vinylic to their respective double bonds would seriously destabilize the double bond if removed, and hydrogens attached to the methyl group jutting off the ring have no incentive to leave the carbon.
Hope this helps!
Answer:
The formation of large molecules from small repeating units is known as <u>Condensation</u> reactions.
Explanation:
Those reactions in which two molecules join together with a elimination of small neutral molecule like H₂O, CH₃OH, HCl e.t.c are known as condensation reactions.
Polymerization reactions are those reactions in which small molecules called as monomers join together to form a large molecule also known as polymers. These reactions are done via different mechanisms among which one is the condensation reaction.
Example:
Proteins (polymer) are made up of amino acids (monomers) through condensation reaction as,
n H₂N-RH-COOH → H₂N-[-RH]n-COOH + n H₂O
In above equation "n" represent large number, H₂N-RH-COOH represent amino acid (monomer) and H₂N-[-RH]n-COOH represent protein (polymer). While, the H₂O eliminated is the small neutral molecule.
<h3>1. <u>Answer</u>;</h3>
= 5.4×10-6 g AgBr
<h3><u>Explanation</u>;</h3>
AgBr(s) → Ag+(aq) + Br-(aq) Ksp = 3.3×10^-13
[Ag+][Br-] = Ksp = 3.3×10^-13 = X²
X = 5.7×10^-7 M = [Ag+] = mol/L AgBr that dissolve
1 mole of AgBr = 187.8 g
Therefore;
= 0.05 L × (5.7 × 10^-7 mol/L) × (187.8 g /mol)
= 5.4×10-6 g AgBr
<h3>2. <u>Answer and explanation;</u></h3>
The two factors that accounts for increased rate of chemical reaction when temperature is increased are:
- <u>Energy factor</u>; enough energy in the collision for the formation of an activated complex, where bonds are breaking and new ones forming. When temperature is increased, a greater number of molecular collisions possess enough energy to activate the reaction.
- <u>Frequency of collisions increases;</u> an increase in temperature makes particles move faster and collide more frequently, increasing the possibility of a reaction be-tween them.
More important factor; Energy factor is more important.
