Answer:

positive deviation from raoults law means when the vapour pressure is higher than the solution is expected to exhibit e.g of one is the mixture of acetone and ethanol

negative deviation means that it is opposed to the total vapour pressure of the solution

Amobarbital sodium react with ethanolic sodium hyrooxide
CaHeK987 [17]

Amobarbital (like all barbiturates) works by being incontestible to the GABAA receptor at either the alpha or the beta subunit.

<h3>What is the mechanism of amobarbital?</h3>

Amobarbital (like all barbiturates) works by binding to the GABAA receptor at either the alpha or the beta subunit. These are compulsory sites that are distinct from GABA itself and also distinct from the benzodiazepine binding site.

Amobarbital is a barbiturate classified as having a halfway duration of action, meaning that the effects of the drug can last from 4-6 amobarbital increases the effects of benazepril by apparatus: pharmacodynamic synergism.

So we can conclude that Amobarbital, 5-ethyl-5-isoamyl barbituric acid like all barbiturates.

A 136 g sample of an unknown substance was heated from 20.0 °C to 40.0 °C. In the process the substance absorbed 2440 J of energ
Julli [10]

Answer:

Option A. The specific heat is 0.897 J/gºC, The Substance is aluminum.

Explanation:

We'll begin by calculating the change in temperature of the substance. This can be obtained as follow:

Initial temperature (T₁) = 20.0 °C

Final temperature (T₂) = 40.0 °C

Change in temperature (ΔT) =?

ΔT = T₂ – T₁

ΔT = 40 – 20

ΔT = 20 °C

Finally, we shall determine the specific heat capacity of the substance. This can be obtained as follow:

Mass (M) = 136 g

Change in temperature (ΔT) = 20 °C

Heat (Q) absorbed = 2440 J

Specific heat capacity (C) =?

Q = MCΔT

2440 = 136 × C × 20

2440 = 2720 × C

Divide both side by 2720

C = 2440 / 2720

C = 0.897 J/gºC

Comparing the specific heat capacity (i.e 0.897 J/gºC) of the substance with those in the table above, the substance is Aluminum.

Thus, option A gives the correct answer to the question.

What is an ionic solid?​
alexandr1967 [171]
Ionic solids—Made up of positive and negative ions and held together by electrostatic attractions. They're characterized by very high melting points and brittleness and are poor conductors in the solid state. An example of an ionic solid is table salt, NaCl.

Which phrase best describes an individual organ?
HACTEHA [7]

Answer:

made of different kinds of tissues

Explanation:

cause that's the only one that makes sense because it goes: cell, tissues,organ,organ system , organism

1. the simplest unit of life - cell

2. a individual organ - would be made of different kinds of tissues

3. tissues - would be made of one kind of cell

4- an organ system - meets all the needs of a organism

also it wouldn't make sense for a individual organ to be made of only one kind of cell so yeah

good luck :) I hope this was right
