Answer:
0.025536g
Explanation:
no. of mole = mass/Mr
mass = Mr × no. of mole
= [23 + 1 + 12 + 3(16)] × 3.04×10^-4
= 0.025536g
= 0.0255g (3 significant figures)
Answer:
Have no C=C double bonds
Explanation:
An saturated compound is the one that cannot undergo certain addition reactions like a hydrogenation, which means that they do not have any double or triple bonds. Therefore Unsaturated Fatty acids do have double bonds, they can be monounsaturated (with one C=C bond) like oleic acid, or polyunsaturated (many C=C bonds) like DHA with 6 unsaturations.
Saturated or unsaturated fatty acids can have short or long hydrophobic tail and both categories can have an even number of carbon atoms:
with 14 C : Myristoleic acid (unsaturated) - Myristic acid (saturated)
with 22 C : DHA (unsaturated) - Behenic acid (saturated)
Any single bond C-C can have free rotation, and even though unsaturated fatty acids presents double bonds they also have single bonds in their hydrocarbon tail.
Answer:
electrovalent compound. saline compound. saltlike compound
Explanation:
The correct answer is amphoteric nature.
Strong acids, alkali metal hydroxides, and strong acids rarely dissolve TeO2 in water. Because it is amphoteric, depending on the solution it is in, it can behave as an acid or a basic. BeO is the most acidic substance found in nature since the acidity of other oxides diminishes as the central atom's electropositivity increases. Amphoteric elements include aluminum oxide, beryllium oxide, tin oxide, and zinc oxide. They react both as an acid and a basic. The solid lattice holds the oxide ions too tightly for them to interact with the water. Most acidic is P2O5. Metal oxides that dissolve in water include sodium oxide (Na2O) and potassium oxide (K2O).
