A phospholipid structure is shown in the picture attached. It has three parts: the hydrophobic tail, the hydrophilic head and the phosphate group in the center. Thus, the function of the phosphate group is to link the hydrophobic and hydrophilic parts of a phospholipid. Specifically, the phosphate group is part of the hydrophilic head. So, it is used to connect the phospholipids to polar compounds.
Yes it’s a soluble because the carbonate should dissolve in any strong acid with much effervescence
Answer:
Solids.
Explanation:
In a solid object, particles are packed tightly together in fixed positions even if in a container.
Answer:
13.4%
Explanation:
Take the molar mass (26.98) of Al x 2 because there are 2 moles in the given compound. Divide this number by the total molar mass of the compound (401.9) this gives you .134. To get a percentage mulitply by 100 for 13.4%.
[(26.98 x 2)/401.9] x 100 =13.4
The solubility product constant, Ksp, is calculated by the product of the concentration of the dissociated ions raise to the stoichiometric coefficient of each ion. We calculate what is asked in this problem as follows:
Ag2SO4 = 2Ag^+ + (SO4)^2-
Ksp = [Ag^+]^2 [SO4^2-]
<span>6.0 x10^-5 = 4x^2 (x) = 4x^3
x = 0.025 M
0.025 mol </span>(SO4)^2- / L ( 1 mol Ag2SO4 / 1 mol (SO4)^2-) (311.799 g / mol ) = 7.69 g Ag2SO4 / L solution
