Given what you have learned about the hydrogen bonding shared between nucleic acids in dna, which pair is more stable under incr
Vinil7 [7]
Cytosine (C) and Guanine (G) are more steady under expanding heat since C and G have three hydrogen bonds while Adenine (An) and Thymine (T) have just two. The more hydrogen bonds there are, the more steady the nucleotides are. More bond dependability requires more warmth vitality to separate the securities, and since G≡C have more hydrogen securities than A=T, they are thusly more steady under expanding heat.

The density of a 1 milliter sample of water is 1 gram. express this density in milligrams per liter
sergeinik [125]

The correct answer is 1000 Kg/M³

Density of water =1-g/cm3.

We know 1- g= 10^-³ Kg

cm³ =(10^-2)³= 10^-6

Substituting we get

Density of water

= 1 x (1x10^-³)/10^-6 Kg/M³

= 1x10^3 = 1000 Kg/M³

<h3>what is density?</h3>

Density is the mass of a material substance per unit volume. Density is defined as d = M/V, where d represents density, M is mass, and V is volume. Density is generally measured in grammes per cubic centimetre. Water, for example, has a density of 1 gramme per cubic centimetre, but Earth has a density of 5.51 grammes per cubic centimetre. Density is sometimes measured in kilos per cubic metre (in metre-kilogram-second or SI units). The density of air, for example, is 1.2 kilogrammes per cubic metre. Textbooks and handbooks list the densities of common solids, liquids, and gases.

How much heat is absorbed by 73.0 grams of ice as it melts at 0°C? How much heat is absorbed by 73.0 grams of liquid as it vapor
kondor19780726 [428]

Answer:

24382 J

162790 J

Explanation:

At 0°C, ice requires a certain amount of heat/energy to break its certain bonds and change its state into liquid water. This amount of heat per gram of ice is known as the latent heat of fusion of ice. And this heat is already detrmined and is equal to 334 J/g. Similarly, For water to convert into vapor at 100°C, it requires a certain amount of heat/energy to break its certain bonds and change its state into gas/vapor. This amount of heat per gram of water is known as the latent heat of vaporization of water, and it is equal to 2230 J/g.

Now, for one gram ice, 334 J heat is required for melting, hence for 73g of ice, 73x334 = 24382 J of heat is required.

Now, for one gram water, 2230 J heat is required for melting, hence for 73g of water, 73x2230 = 162790 J of heat is required.
