A, milligrams because rice is very small therefore you'd need to use a very small unit of measurement.
Answer:
a. The new pressure is 606,25 Torr.
b. -243,9°C is needed to reach the pressure of 7250 Torr.
Explanation:
Gay Lussac's law for gases says that if the volume in a gas remains constant, the pressure will be directly proportional to the temperature change.
P1 . T1 = P2. T2
(Temperature must be in K)
725 Torr . 291 K = P2 . 348 K
(725 Torr . 291 K) /348 K = P2
606,25 Torr = P2
725 Torr . 291K = 7250 Torr . T2
(725 Torr . 291K) /7250 Torr = T2
29,1 K = T2
T° K - 273 = T°C
29,1 K -273 = -243,9°C
Answer:
The desirable characteristic of Barium suspension are:
<u>Thick layering</u>
<u></u>
Explanation:
First know the meaning of the terms :
1. Rapid flow
2. Thick layering
3. Good mucosal adhesion\
1. Rapid flow : The lower the viscosity of the solution , more is its flow in the solution. For example : Honey has more viscosity so it flows slowly . On the other hand water flow faster.
2. Thick layering : layering is the deposition of one layer of the liquid over other. The deposited layer can be of different substance.
3. Mucosal Adhesion : It is the adhesion(attraction) between two materials ,one of which is mucous.It is attractive force between the drug and the mucus inside the body.
Barium suspension:
<em>It is not a Good mucosal adhesion material because of low solubility in water and lipid .</em>
<em>Only those solution are good in adhesion which have higher solubility in water.</em>
It is widely used as the contrast media for the examination of gastrointestinal because of its <u>Thick Layering Property. It has the consistency of thick glass . At room temperature it is called "warm thick milk"</u>

To covert from moles to atoms times the number of moles by Avogadro's Number (6.022×10²³)
4.0 × 6.022×10²³ = 2.4088×10^24
