Answer:
Chemical reactions that take place inside living things are called biochemical reactions. Explanation:The sum of all the biochemical reactions in an organism is referred to as metabolism. Metabolism includes both exothermic (heat-releasing) chemical reactions and endothermic (heat-absorbing) chemical reactions.
The property to be used is sieving. you get a bowl and a sieve when you pour the sand and salt,the salt being the small particle sieve to the bowl while the sand remain on the sieve as residue
Osmosis through a semipermeable membrane

Answer:
Explanation:
Hello,
In this case, for the dissociation of the sodium hydroxide into sodium and hydroxyl ions we have:
Which is a 100% dissociation as sodium hydroxide is a strong base, therefore, the concentration of the hydroxyl ions are 1.0x10⁻⁹. For that reason, the pOH could be computed as:
Finally, from the definition of pH, we have:
Best regards.
No, dimethyl amine and triethyl amine are not more soluble in water. Both are soluble in water but not more soluble in water. These are also soluble in alcohol.
Dimethyl amine is a secondary amine while triethyl amine is a tertiary amine. Generally, the small amines are more soluble in water. As the hydrocarbon chain goes on increasing, the solubility goes on decreasing.
