Fed [463]

Answer:

Heating water with an open flame

Explanation:

Remember, we are told in the label that Acetone is a "flammable liquid and vapor." Being flammable means the substance can easily be set on fire, and we would expect an open flame from heating water to trigger an explosion (a disaster) in which the Acetone is set on fire causing life-threatening dangers to the second group of students.

PCL was mixed with gelatin to make a blend for elctrospun fibrous scaffold encapsulating growth factor that was admixed in the p

shusha [124]

Answer:

Explanation:

First PCL to form a scaffold, combined with gelatin.

They are made by first three forms A) made by just PCL.B) made by gelatin ratio PCL is 3:1 and last is C) made by gelatin PCL.

The decoration rate is 1%, 25% and 50% respectively.

A) Growth factor is stuck in 21 days, and can not spread. In this case in vivo experiment for 7 days used highly degradable scaffold use the ability to break down due to decomposition in vivo degradation rate depends on the scaffold's acid byproduct impact.

B) the amount of scaffolded degradation.

First, with scaffold A.

10 mg scaffold weight A= 1 per cent degradation.

Following degradation wt is 9.967=? Degradation per cent.

So, degradation (9.967* 1)/10= 0.9967 per cent.

Likewise for C) scaffold c 10 mg wt. Loss of 50 per cent.

After wt 8.33=? Degradation per cent.

Degradation (8.33* 50)/10=41.65 per cent.

Scaffold c degrades significantly, since the loss of wt is even greater.

Which of the following is a chemical property of vinegar? A. The pH of vinegar is around 2.4. B. Vinegar freezes at around 2°C.

vladimir2022 [97]

I think the correct answer from the choices listed above is option A. The chemical property of a vinegar is that the pH of vinegar is around 2.4. It tells something about the concentration of hydrogen ions in the solution. The other choices given only describe the physical properties of the substance.
