Problem: In each of the following situations, what type of filtration device would you use?
Shtirlitz [24]

Answer:

A. Filtration by gravity

B. Syringe filter

C. Syringe filter

D. Filtration by gravity

E. Syringe filter

F. Filtration by gravity / Vacuum filtration.

Explanation:

Filtration is a mixture of separation techniques to separate solids from liquids. The filtration can be done by gravity, by pressure or by vacuum. The correct filtration is chosen by the characteristics of the mixture.

A. The particles are big, so it's possible to use a funnel and a filter paper with the right numeration (the diameter of the pores must be smaller than the particles). The filtration will happen by gravitation.

B. Because the volume is too small (1 mL), it can be used as a syringe filter, a small device in which the solution is put in the syringe, and then, by pressure, the solution goes from the filter. Thus, the filtration is done by pressure.

C. As letter B, the small volume indicates a pressure filtration by a syringe filter.

D. In this case, such as letter A, it's possible to use gravitation filtration.

E. Because of the volume is too small, such as letters B and C, the pressure filtration by a syringe filter is more indicate.

F. In this case, the filtration can be done by gravitation, and a vacuum can be added to accelerate it because is a small volume with solid impurities.

freezing a sealed full bottl of water leads to a broken bottle and freezing a sealed full flexible wall container of n butyl alc
Nataly [62]

Answer:

See explanation

Explanation:

We know that water begins to expand at 4°C. This is generally referred to as the anomalous behavior of water.

The implication of this is that ice has a greater volume than water. Thus ice is less dense than liquid water.

n-butyl alcohol has much less density than water. This accounts for the fact that water upon freezing breaks the bottle while n butyl alcholol leads to a container with concave walls.

Hence the density of ice is much higher than the density of n butyl alcohol.

A 1M solution is made of each item in a pair. When would this combination create a buffer? Chose the pairs below that you could
monitta

Answer:

b. HCOOH/ NaHCOO.

Explanation:

A buffer system may be formed in one of two forms:

  • A weak acid with its conjugate base.
  • A weak base with its conjugate acid.

Chose the pairs below that you could use to make a buffered solution.

a. HCI/NaOH. NO. HCl is a strong acid and NaOH is a strong base.

b. HCOOH/ NaHCOO. YES. HCOOH is a weak acid and HCOO⁻ (coming from NaHCOO) is its conjugate base.

c. HNO₂/H₂SO₃. NO. Both are acids and they are unrelated to each other.

d. NaNO₃/ HNO₃. NO. HNO₃ is a strong acid.
