What are the characteristics of non-ideal solutions? a. The solute-solute and solvent- solvent interaction is different fromm th
finlep [7]

Answer:All the above

Explanation:

Non-ideal solutions are those solutions which do not obey Raoult's law in any conditions.

The molecular interactions of two components that is solute and solvent  are different.

If there are two components A and B then the molecular interaction between A-A,B-B would be different from the molecular interactions in A-B .

The enthalpy of mixing and volume of mixing for non-ideal solutions have  non zero values.

Enthalpy of mixing can be negative or positive in case of non-ideal solutions. If the enthalpy of mixing is negative so energy has been  released upon mixing the two components and if enthalpy of mixing is positive then energy is absorbed upon mixing the two components.

Non-ideal solutions are simply those solutions which are not ideal hence they should not be having the characterstics of ideal solutions.

For ideal solutions the molecular interactions between  the two components are equal.

So the molecular interaction between A-A,B-B  would be equal to the molecular interaction between A-B. Also the enthalpy of mixing and volume of mixing for ideal solutions are zero hence all the statements provided here are correctly charactersing non-ideal solutions.

Why are lightning formed in clouds?
VladimirAG [237]

Explanation:

Because opposites attract, the negative charge at the bottom of the storm cloud wants to link up with the ground’s positive charge. Once the negative charge at the bottom of the cloud gets large enough, a flow of negative charge called a stepped leader rushes toward the Earth. The positive charges at the ground are attracted to the stepped leader, so positive charge flows upward from the ground. When the stepped leader and the positive charge meet, a strong electric current carries positive charge up into the cloud. This electric current is known as the return stroke. We see it as the bright flash of a lightning bolt.

Thunder and lightning occur at roughly the same time although you see the flash of lightning before you hear the thunder. This is because light travels much faster than sound

Where in the cell do transcription and translation take place? Transcription takes place in a protein, and translation takes pla
oksano4ka [1.4K]

Answer:

The correct answer will be option-Transcription takes place in the nucleus, and translation takes place in ribosomes.  

Explanation:

The regulation of gene is regulated and controlled by two main processes of central dogma called transcription and translation.

Transcription is the process of formation of messenger RNA or mRNA from a single strand of DNA whereas translation is the formation of protein from mRNA.

This process takes place in different sites in prokaryotes and eukaryotes. In prokaryotes, both transcription and translation take place in the cytoplasm but in eukaryotes, the transcription takes place in the nucleus whereas translation takes place in the ribosomes present in the cytoplasm.

Thus, the selected option is the correct answer.

Water's heat of fusion is 80. cal/g , its specific heat is 1.0calg⋅∘C, and its heat of vaporization is 540 cal/g . A canister is
dem82 [27]
Refer to the diagram shown below.

State 1:
The heat of fusion is required for the ice to become water.
The amount of heat required is
Q₁ = (330 g)*(80 cal/g) = 26,400 cal

State 2:
Sensible heat is required to raise water at 0 C to the boiling point of 100 C.
The heat required is
Q₂ = (430g)*(1 cal/(g-C))*(100 C) = 43,000 cal

State 3:
The heat of vaporization is required to boil off the water.
The heat required is
(430 g)*(540 cal/g) = 232,200 cal

Total heat absorbed is
Q₁+Q₂+Q₃ = 301,600

Answer: 301,600 cal  or 301.6 kcal
