Answer: b suspension
a suspension is a heterogeneous mixture that contains solid particles sufficiently large for sedimentation . The particles may be
visible to the naked eye, usually must be larger than one micrometer , and will eventually settle, although the mixture is only classified as a suspension when and while the particles have not settled out. A suspension is a heterogeneous mixture in which the solute particles do not dissolve , but get suspended throughout the bulk of the solvent , left floating around freely in the medium. [1] The internal phase (solid) is dispersed throughout the external phase (fluid) through mechanical agitation , with the use of certain excipients or suspending agents.
An example of a suspension would be sand in water. The suspended particles are visible under a
microscope and will settle over time if left undisturbed. This distinguishes a suspension from a colloid , in which the suspended particles are smaller and do not settle.
Colloids and suspensions are different from
solution , in which the dissolved substance (solute) does not exist as a solid, and solvent and solute are homogeneously mixed.
Answer:
7,9,11
Explanation:
this is because water includes 0H, which would mean that it is more than 6
Answer:
Concentration of oxygen (O2) = 2.7 x 10^-6 M
Explanation:
The concept of Henry's law was applied as this shows the relationship between solubility and the pressure in atm, and sometimes it is related to the concentration in molar as it was applied and shown in the attachment.
Answer:
The answer is C: .588 M
Explanation:
[CaCl2] = mols CaCl2/Liters of solution
molar mass of CaCl2 = 110.98 g/ 1 mole (from periodic table)
800 mL/1000 mL = .8 Liters of solution
1)
52.3g CaCl2/ 110.98g = .47 mole
2)
.47 mole/.8 L = .589 M
So the answer is C
Answer:
It allows for an increased exposed surface area and hence a faster rate of reaction between the reacting agents and the organelles.
Explanation:
Chemical reaction is dependent on the surface area of contact between the reacting parties. Having a folding surface as seen in many cell organelles gives an advantage of increasing the surface area available for contact between the reacting agent and the organelles. This ensures that reaction is faster and more effective.
