Answer:
Chemical digestion is a vital part of the digestive process. Without it, your body wouldn't be able to absorb nutrients from the foods you eat, also chemical digestion uses enzymes to break down food
mechanical digestion involves physical movements, such as chewing and muscle contractions,
Explanation:
Hello!
Use the equation d = s · t where:
s = speed
t = time
d = distance
Plug in the given distance and speed:
20 = 12 ·t
Divide both side by 12 to isolate for t:
20/12 = t
Simplify:
5 / 3 = t
Therefore, it took 5/3 hours to bike. We can convert this to minutes if necessary:
5/3 · 60 min (in one hour) = (60 · 5) / 3 = 100 min.
Answer: Two effects may occur during high current flow: 1) the wire may become overheated to the point that surface oxidation or even evaporation may take place, 2) at the connection points at each end of the wire, especially if the terminations are of a different type of metal than the wire, some atoms may migrate into or out of the wire.
One of the hydrogens in the NH3 is replaced in the first reaction by the methyl group, or -CH3. The NH3 can have more than one H substituted for it, therefore the final product frequently comprises a blend of methylamine, dimethylamine, and trimethylamine.
A halogenoalkane and ethanolic ammonia can be used in a nucleophilic substitution process to produce primary aliphatic amines like methylamine (CH3NH2).
NH3 + CH3Cl = HCl + CH3NH2
The process is challenging because any unreacted ammonia can react with the generated HCl:
NH3+HCl yields NH4Cl.
Since the N in CH3NH2 still has a single pair of electrons, it can act as a base and interact with the HCl that is created in one of the following ways:
CH3NH2+HCl becomes CH3NH3+Cl.
or as a nucleophile and react with any chloromethane that hasn't been reacted:
(CH3)2NH + HCl = CH3NH2 + CH3Cl
