Answer: B.)
Explanation: Heat flows from pan to sounroundings
Answer:
A) secondary amide
Explanation:
When carboxylic acid reacts with a primary amine, a condensation reaction takes place with the elimination of a water molecule .
For example, ethanol reacts with methylamine which is a primary amine gives N-Methylacetamide and a water molecule as:

The bond formed which is
O
||
-- C ---NH ---
is known as secondary amide group as only one hydrogen is attached to nitrogen atom in the amide bond.
Hey there!
Molar mass C2H6O = 46.0684 g/mol
Number of moles:
n = mass of solute / molar mass
n = 70.6 / 46.0684
n = 1.532 moles
Therefore:
M = number of moles / volume ( L )
M = 1.532 / 2.25
= 0.680 M
Hope that helps!
Answer:
<em>The answer to your question is </em><em>True</em>
Explanation:
CH2O is a polar molecule. It has three polar bonds that are arranged asymmetrically, thus allowing their dipole moments to add up and give the molecule an overall dipole moment. CH2O has a central carbon atom that forms two single bonds with the two hydrogen atoms and a double bond with the oxygen atom.
