Polyester and polyamide would be two synthetic polymers, created by condensation reaction.
Answer:
V = 1.66mL acetic acid
Explanation:
dilution formula:
V1*C1 =V2*C2
⇒ V1*(6M) = (100mL)*(0.1M)
⇒ V1 =( (100mL) * (0.1M) ) / (6M)
⇒ V1 = 1.66mL acetic acid
Answer:
One calorie is equivalent to 4.18joules
Answer:
The periodic table helps organize all the elements found in the world and tells a great deal of information on each of the elements such as their atomic mass, symbol, atomic number, and more. It even is organized into groups (columns) and periods (rows). The elements in the same group mostly have similar chemical properties. In short, the periodic table is a list of the elements that make up the world around you.
Explanation:
Due to electronegativity difference between H and F atom.
<h3>
What is the reason for the difference ?</h3>
- The bond length of HF is 92 pm. It is 16% shorter than the sum of the covalent radii of H (37 pm) and F (72 pm).
- The shorter of the bond length is due to the difference in electronegativity between H and F atom. The electronegativity of F is 4.0, whereas the electronegativity of H is 2.1.
- Greater the difference of electronegativity between the bonded atoms, shorter will be the bond length.
- As becomes smaller i.e. as we proceed from HF to HI, this effect becomes lessens and bond length will be more predictable.
Thus from the above conclusion we can say the difference in electronegativity between H and F atom this is the reason for shorter bond length of HF.
