Answer:

Genes are segments of DNA that are located on the chromosomes of each cell.

Explanation:

Chromosomes are basically tightly bundled thingies containing genes, DNA, whatever. Phenotype and genotype have nothing to do with chromosomes, that's just how WE describe them.

Which of the following ions is formed when an acid is dissolved in a solution?
kiruha [24]

Answer:

  • <u><em>H⁺</em></u>

Explanation:

There are three definitions of acids: Arrhenius, Bronsted - Lowry, and Lewis.

An Arrhenius acid is a substance that when dissolved in water will release a proton (H⁺ or hdyronoum, H₃O⁺) in solution.

The definition of Bronsted-Lowry is not limited to aqueous solution: an acid is a substance that releases protons in any solvent. So it includes, the Arrhenius acids but also other acids.

The Lewis Acid definition is wider. It includes both Arrhenius and Bronsted-Lowry acids and other substances that do not release protons. A Lewis acid is a substance that accepts an electron pair.

Thus, <em>when an acid is dissolved in a solution, following Bronsted-Lowry definition, </em><u><em>H⁺ ions are formed.</em></u>

Fill in the blank with the correct word pair: The heart exchanges blood that is oxygen _______ with blood that is oxygen _______
devlian [24]

Answer:

The second one - rich/poor

Explanation:

However it would be in reverse order so when filling in the blank, poor would come first then rich

but if you are not able to change it then you can just leave it like that.

I hope this helped☺

Use the fact that to determine how much the pressure must change in order to lower the boiling point of water by a small amount
erma4kov [3.2K]

Complete Question

Use the fact that d\mu=\frac{V}{N}dp-\frac{s}{N}dT to determine how much the pressure must change in order to lower the boiling point of water by a small amount 3.20e-01 K. You may assume that the entropy and density of the liquid and gas are roughly constant for these small changes. You may also assume that the volume per molecule of liquid water is approximately zero compared to that of water vapor, and that water vapor is an ideal gas. Useful constants: Atmospheric pressure is 101300 Pa The boiling point of water at atmospheric pressure is 373.15 K The entropy difference between liquid and gas per kilogram is 6.05e 03 J/kgK The molecular weight of water is 0.018 kg/mol. (a) 0.00e 00 Pa (b) 1.14e 03 Pa (c) 6.85e 26 Pa (d) 4.24e 05 Pa (e) 3.81e 28 Pa

Answer:

Correct option is B

Explanation:

From the question we are told that:

Given Equation d\mu=\frac{V}{N}dp-\frac{s}{N}dT

Change of boiling point \triangle H=3.20e-01 K

Generally the equation for Change in time is mathematically given by

  d\mu=\frac{V}{N}dp-\frac{s}{N}dT

  dp=\frac{s}{v}dT

Where

    s=Entropy\ difference *molar\ weight

    s=6.05*10^3*0.018j/mol.k

And

    V=\frac{RT}{P} (from ideal gas equation)

Therefore

 dp=\frac{Ps}{RT}dT

 dp=\frac{101300*6.05*10^3*0.018}{8.314*373.15}3.20*10^{-1}

 dp=1137.873pa

 dp=1.14e 03 Pa

Therefore correct option is B
